Control químico en mango (Mangifera indica L.) contra escama blanca y trips en Tierra Blanca, Veracruz, México.
Provedor de dados: 32
Autores: García Escamilla, Paul.
El estudio se realizó de enero a mayo del 2011 en la huerta comercial de mango (Mangifera indica) var. Manila “El Pantano” en Tierra Blanca, Veracruz, México. Se evaluaron aceite mineral, azufre, spinosad e imidacloprid para controlar escama blanca (A. tubercularis) y trips (F. invasor y F. cephalica), que son las principales plagas que atacan a este cultivo. Se llevaron a cabo muestreos periódicos para estimar las poblaciones de las plagas a combatir. Los resultados obtenidos se analizaron con el programa SAS para comparar medias con la prueba de medias de LSD (diferencia mínima significativa) y la prueba de Friedman con un valor de alfa de 0.05%. El aceite mineral, el azufre y el spinosad fueron más eficientes para el control de escama blanca. No se...

Toxicidad de insecticidas sobre tres especies de depredadores de Diaphorina Citri (Hemíptera: Liviidae).
Provedor de dados: 32
Autores: González Carrillo, Jesús Ascención.
El psílido asiático de los cítricos, Diaphorina citri (Hemiptera: Liviidae), es el principal vector del agente causal del Huanglongbing (HLB) en cítricos en el mundo. El control de esta plaga se realiza principalmente con insecticidas a pesar de la presencia de sus enemigos naturales. La integración de los enemigos naturales debe ser considerada dentro de un programa de manejo integrado de esta plaga en cultivos de cítricos, por lo que en este trabajo se evaluó la toxicidad de tres insecticidas sobre tres de los depredadores más comunes en cítricos, los crisópidos Ceraeochrysa valida y Chrysoperla rufilabris, y el coccinélido Olla v-nigrum. Se utilizaron dos insecticidas de contacto (bifentrina y spirotetramat) y un sistémico (thiamethoxam) bajo dos...

Silicon application as an auxiliary method to control diamondback moth in cabbage plants
Provedor de dados: 75
Autores: Telles,Camila C; Freitas,Luciana M de; Junqueira,Ana Maria R; Mendonça,Renata S de.
ABSTRACT Integrated pest management (IPM) strategies are among the factors promoting plant resistance to pests, and silicon application may increase this resistance. Thus, the aim of this research was to evaluate the control of diamondback moth (DBM), Plutella xylostella (Lepidoptera, Plutellidae) through foliar application of silicon in cabbage crops. The experiment was conducted in the vegetable producing area of Água Limpa Farm, Universidade de Brasília, Distrito Federal, Brasil. The experimental design was of randomized blocks with nine treatments and four replicates, totaling 36 plots. The applied treatments consisted of Agrosilicon® (10.5% Si) (T1), Sifol® (12% Si) (T2), deltamethrin 25 g L-1 (Decis® 25 EC) (T3), Bacillus thuringiensis, 33.60 g L-1...

Nova Metodologia para avaliar a deposição de micoinseticida granulado, aplicado via aérea, para controle de cigarrinhas-da-raiz da cana-de-açúcar.
Provedor de dados: 14
Autores: ALVES, R. T.; CRUVINEL, P. E.; SOARES, R. M.; MALAQUIAS, J. V.
O controle biológico é uma importante ferramenta para ser utilizada no manejo integrado de insetos-praga. A formulação granulada de fungo Metarhizium anisopliae ainda é uma das mais utilizadas em canaviais do Brasil, porém existe uma dúvida sobre quantos esporos do fungo chegam na base da planta de cana quando aplicados de avião. O objetivo deste estudo foi desenvolver metodologia para avaliar a deposição de micoinseticida granulado, aplicado via aérea, para controle de cigarrinhas-da-raiz da cana. Aplicou-se o fungo M. anisopliae na dose de 1,4 x 1013 conídios/ha, na forma granulada, por meio de avião agrícola com aplicador Swathmaster, na quantidade de 8 kg/ha, e dose de 1,8 x 1013 para 10 kg/ha. Cada parcela teve 48 placas de Petri para coleta dos...

Toxicite et persistance en milieu marin d'un insecticide derive des benzoylurees: le diflubenzuron.
Provedor de dados: 5
Autores: Alzieu, Claude.
The laboratory tests showed that the diflubenzuron does not present acute toxicity to shellfish and fish, but can affect the survival rate of Artemia salina and Palaemonetes varians, when its concentration rises to the level of its water solubility. The insecticide persistence in sea water had been found to be 3 weeks and its concentration factor in the fish after 52 days of exposure was very low. The use of dimilin in coastal zones for the eradication of caterpillars seems to have an insignificant impact on marine ecosystem, particularly on the molluscs.

Effects of twelve pesticides on larvae of oysters (Crassostrea gigas) and on two species of unicellular marine algae (Isochrysis galbana and Chaetoceros calcitrans)
Provedor de dados: 5
Autores: His, Edouard; Seaman, Matthias.
The effects of seven herbicides, four insecticides and one molluscicide were tested at concentrations of up to 10 mg/l on larvae of oysters, Crassostrea gigas (9 days exposure), and on laboratory cultures of the algae Isochrysis galbana and Chaeloceros calcilrans (21 days exposure). Ali of the pesticides tested had significant toxic effects on at least one of the test organisms. The strongest effects were those of lindane and isoproturon on survival and growth of C.gigas larvae, and of isoproturon and carbetamide on growth of Isochrysis and Chaeloceros cultures. The log-probit model for the relationship between dosage and effect, and Haber's rule for the relationship between duration of exposure and effect, hardly ever applied to our data. In sorne cases...

Mathematical modelling of vector-borne diseases and insecticide resistance evolution
Provedor de dados: 80
Autores: Kuniyoshi,Maria Laura Gabriel; Santos,Fernando Luiz Pio dos.
Abstract  Background: Vector-borne diseases are important public health issues and, consequently, in silico models that simulate them can be useful. The susceptible-infected-recovered (SIR) model simulates the population dynamics of an epidemic and can be easily adapted to vector-borne diseases, whereas the Hardy-Weinberg model simulates allele frequencies and can be used to study insecticide resistance evolution. The aim of the present study is to develop a coupled system that unifies both models, therefore enabling the analysis of the effects of vector population genetics on the population dynamics of an epidemic.  Methods: Our model consists of an ordinary differential equation system. We considered the populations of susceptible, infected and recovered...

Grain yield and termite damage in rice by compaction on the furrow and seed treatment
Provedor de dados: 86
Autores: Pinheiro,Veneraldo; Stone,Luís Fernando; Barrigossi,José Alexandre Freitas; Nascente,Adriano Stephan.
Abstract The objective of this work was to determine the effects of soil compaction pressure on the sowing furrow and of seed treatments with insecticides on grain yield and on termite damage in upland rice plants under no-tillage, in the Center West region of Brazil. Three experiments were carried out, consisting of five seed treatments combined with three (first experiment) or four (second and third experiments) compaction pressures in a randomized complete block design, in a factorial arrangement. The seed treatments were: T0, without treatment; T1, imidacloprid+thiodicarb; T2, thiamethoxam; T3, carbofuran; and T4, fipronil+pyraclostrobin+thiophanate-methyl. The compaction pressures applied were: 25, 42, and 268 kPa, in the first experiment; and these...

Autores: Ray,   Daryll E.; Slinsky,   Stephen P.; Torre Ugarte,   Daniel de la; Tiller,   Kelly.
This research estimates farm-level impacts of a potential ban on organophosphates and carbamates under the FQPA.  Insecticide expenditure and first- and fifth-year yield impacts are estimated for five Tennessee representative farms.  Results indicate that within five years, the ban could reduce net farm income on Tennessee farms by 16 to 46 percent.

Insecticide Use and Crop Selection: A South Dakota Case Study
Provedor de dados: 31
Autores: McDonald,   Tia Michelle; Keating,   Ariel Ruth; Fausti,   Scott W.; Li,   Jing; Lundgren,   Jonathan G.; Catangui,   Mike.
South Dakota has recently experienced a significant increase in the proportion of acres treated with insecticide. Unfortunately, data on insecticide usage by crop at the county level is not available. The following case study seeks to uncover the reasons for this increase by analyzing county-level data in South Dakota with a fixed effects panel regression. The study links the proportion of acres planted for a specific crop to the proportion of total acres treated with insecticide. This approach provides insight on how changing cropping patterns in South Dakota have influenced insecticide use.

Autores: Silva,William Ribeiro da; Soares-da-Silva,Joelma; Ferreira,Francisco Augusto da Silva; Rodrigues,Iléa Brandão; Tadei,Wanderli Pedro; Zequi,João Antonio Cyrino.
ABSTRACT The aim of this study was to analyze the effectiveness of different control agents of Aedes aegypti and Aedes albopictus associated with ovitraps under laboratory and field conditions. Five treatments were used: grass infusion + Bacillus thuringiensis israelensis (gI + Bti), grass infusion + Saccharopolyspora spinosa (gI + Ss), grass infusion + Pyriproxyfen (gI + P), distilled water + Toxorhynchites haemorrhoidalis (dW + Th), and grass infusion (gI) (control). The highest mean number of eggs of both species were obtained with grass infusion in the laboratory. Among control agents, the lowest mean of A. aegypti eggs occurred with gI + Ss and the lowest mean of A. albopictus eggs occurred with dW + Th. There was no difference between treatments in...

ABSTRACT The aim of this study was to evaluate the residual effect of pesticides sprayed on peach orchards on S. zeamais. The study consisted of two experiments, according to the method of pesticide application. For Experiment I, pesticides were directly sprayed on peach trees and in Experiment II, the application of pesticides was performed under laboratory conditions. In both Experiments, the effect of pesticides was assessed in laboratory through the release of ten weevils per peach fruit. The effect of treatments was assessed by variable number of surviving insects. The results for pesticides [a.i. (ml or g.100L)] have shown that application of treatments in the field (Experiment I), malathion (200) presented persistence at 1DAT (Days after treatments...

Brown planthopper (BPH) is a major insect pest of irrigated rice cultivation areas in lower north, central and northeast Thailand. The field experiments were conducted to evaluate the efficacy of nine insecticides to control BPH in farmers’ fields at Suphan Buri, Nakhonayok and Ubon Ratchathani provinces. The results showed that the sulfoxaflor 50 % WG and pymetrozine 50 % WG were the most effective insecticides. The ratios of BPH/mirid bug (MB) in the buprofezin and pymetrozine fields were lower than other fields, which may indicate the less toxicity to MB compared with other insecticides. Moreover, toxicity of each insecticide to MB was investigated using a leaf dipping method and the result indicated that pymetrozine 50 % WG was the lowest toxicity to...

TOXIC ACTIVITY OF PYRETHROIDS IN Lutzomyia longipalpis (DIPTERA: PSYCHODIDAE) FROM MAGDALENA RIVER BASIN, COLOMBIA
Provedor de dados: 37
Autores: SANTAMARIA,Erika; MARCELÓ,Catalina.
ABSTRACT The study aimed to determine the toxicity of lambda-cyhalothrin, alpha-cypermethrin, and deltamethrin in L. longipalpis, through concentration-mortality bioassays. The test here was performed following WHO guidelines, but instead of using exposure WHO recipients and impregnated papers, 250 ml Wheaton glass bottles treated with 1 ml of insecticide solution were used. Batches of ten females of L. longipalpis were exposed to five concentrations of each pyrethroid that caused between 5 and 100 % mortality in this species. After 1 h of exposure, the females were transferred to observation recipients, and mortality was recorded 24 h later. The lethal concentrations (g/ml) that killed 50 and 95 % (LC50 and LC95) of the exposed L. longipalpis females were...

BACKGROUND: Essential oils extracted from aromatic and medicinal plants have many biological properties and are therefore an alternative to the use of synthetic products. The chemical composition of essential oils from two medicinal plants (Eucalyptus globulus and E. lehmannii) was determined and, their insecticidal effects on the third and fourth larval stages of Orgyia trigotephras were assessed. RESULTS: Larvae were collected from Jebel Abderrahmane (North-East of Tunisia), conserved in groups of 50/box (21 × 10 × 10 cm) at a temperature of 25°C. Larvae were tested for larvicidal activities of essential oils. Each oil was diluted in ethanol (96%) to prepare 3 test solutions (S1 = 0.05%, S2 = 0.10% and S3 = 0.50%). Essential oils were used for contact,...

Autores: Georgieva,Elenka; Stoyanova,Stela; Velcheva,Iliana; Yancheva,Vesela.
This work aimed to study the effect of new neonicotinoid thiamethoxam on the histological structure of common carp (Cyprinus carpio, L.) gills. Three experimental groups of fish were treated with 6.6, 10 and 20 mg/l thiamethoxam in laboratory conditions. Results showed different histological changes in the gill epithelium, which included lamellar lifting, edema, proliferation of the glandular cells and epithelium, covering the gill filament, fusion and degenerative alterations. The blood circulatory system showed mainly vasodilatation. All thiamethoxam concentrations activated compensatory-adaptive mechanisms, which caused pathological changes in the gills. Moreover, there was a tendency towards the enhancement of the gill histological changes, whose...

Fluctuations in the Brazilian milk market force small milk producers to find temporary trade alternatives, which include selling raw milk to people who prefer this type of milk rather than heat-processed milk. Considering the importance of these small milk producers to the market and the well-known health risks associated to consumption of raw milk, this study evaluated the microbiological quality and the presence of Listeria monocytogenes, Salmonella spp., chlorine, antimicrobials and insecticides (organophosphates and carbamates) in raw milk produced in 210 small and medium farms located in four important milk-producing Brazilian states (Paraná, São Paulo, Minas Gerais and Rio Grande do Sul). In 66% of the selected farms the milking was manual. In 33% of...

Residual Effect of Pesticides used in Integrated Apple Production on Chrysoperlaexterna (Hagen) (Neuroptera: Chrysopidae) Larvae
Provedor de dados: 117
Autores: Moura,Alexandre P; Carvalho,Geraldo A; Botton,Marcos.
Temperate fruit crops are an important economic activity for growers in southern Brazil. However, several pest species are associated to apple (Malus domestica Borkh.) crops in Brazil. Pesticides are largely used to control them and one way to change this is to combine selective pesticides and predator insects. The goal of this research was to evaluate the effects of the abamectin, carbaryl, fenitrothion, methidathion, sulfur, and trichlorfon pesticides on the survival and stage length of larvae and pupae, adult oviposition from treated larvae, and hatched eggs of two Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) populations. The compounds were sprayed on glass plates in accordance with the International Organization for Biological Control...

Ovicidal effect of some insecticides on the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Yponomeutidae)
Provedor de dados: 117
Autores: Mahmoudvand,Mohammad; Sheikhi Garjan,Aziz; Abbasipour,Habib.
The diamondback moth, Plutella xylostella (Lepidoptera: Yponomeutidae), is a serious threat to Brassica vegetables in Iran, including Tehran province. The ovicidal effects of different classes of insecticides on P. xylostella were investigated, using three fixed doses (based on commercial formulations). At the lowest concentration (500 mg L-1), the mortality effect of hexaflumuron and pyridalyl was higher than the other insecticides examined. Fipronil, hexaflumuron and spinosad and pyridalyl, however, showed high toxic effects at the median dose (1000 mg L-1). On the other hand, at high concentration (2000 mg L-1), all insecticides except lufenuron and indoxacarb (EC formulation) caused more than 85% mortality. Overall, these findings indicate that...

Deposit of pesticides without and with adjuvants on citrus seedlings following different intervals of artificial rain
Provedor de dados: 65
Autores: Decaro,Ricardo Augusto; Decaro Junior,Sergio Tadeu; Ferreira,Marcelo da Costa.
ABSTRACT: For a crop protection product to achieve its goal, the product must be applied and remain on the leaves until it is absorbed. This situation may be compromised due to rainfall after spraying, thus necessitating reapplication which increase the overall cost. Application technology research has focused on alternatives and solutions to mitigate this effect through the use of adjuvants. The objective of this research was to evaluate the deposit of spraying liquid on citrus seedlings using the products spirodiclofen, propargite, imidacloprid, lambda cyhalothrin, copper oxychloride, and copper hydroxide with water mixed with the adjuvants polydimethylsiloxane and phosphatidylcholine. Seedlings were subjected to simulated rains of 10mm at intervals of...
