A potent larvicidal agent against Aedes aegypti mosquito from cardanol Anais da ABC (AABC)
PAIVA,DERISVALDO R.; LIMA,DÊNIS P. DE; AVVARI,NAGA P.; ARRUDA,EDUARDO J. DE; CABRINI,ISAIAS; MARQUES,MARIA RITA; SANTOS,EDSON A. DOS; BIAGGIO,FRANCISCO C.; SANGI,DIEGO P.; BEATRIZ,ADILSON.
ABSTRACT Cardanol is a constituent of Cashew Nut Shell Liquid that presents larvicidal activity against Aedes aegypti. The isolation of cardanol is somewhat troublesome, however, in this work we describe an efficient and inexpensive method to obtain it as a pure material. The compound was used as starting material to make chemical transformation leading to saturated cardanol, epoxides and, halohydrins. These derivatives were tested for toxicity against Aedes aegypti larvae. The results showed that iodohydrins are very promising compounds for making commercial products to combat the vector mosquito larvae presenting a LC50 of 0.0023 ppm after 72 h of exposure.

Age and time exposure-related toxicity of fenthion to male and female Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) Anais da SEB
Humeres,Eduardo; Da Cruz,Ivana B.M.; Oliveira,Alice K. de.
Effect of age, sex and time exposure of Anastrepha fraterculus (Wied.) to toxicity of fenthion was evaluated. The age of the flies was important to the appearance of the first intoxication symptoms; males and females of reproductive ages (30 and 60 days-old, respectively) were less susceptible to insecticide than flies in the remainder ages (four and 120 days-old). The effect of body weight on insect intoxication was not detected. LT 50 biossay with fenthion (varying from 3-7 minutes) showed a lower susceptibility of males than females at all ages. Adults of both sexes and 30 days-old submitted to continuous and discontinuous exposure to fenthion did not show toxic cumulative effect of the insecticide. The statistical analysis suggests a possible general...

Seixas,Paula Tatiana Lopes; Demuner,Antonio Jacinto; Alvarenga,Elson Santiago; Barbosa,Luiz Claudio Almeida; Marques,Ana; Farias,Elizeu de Sá; Picanço,Marcelo Coutinho.
ABSTRACT: The demand for effective insecticides in pest control with low toxicity to the non-target organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absinthium, A. camphorata, A. dracunculus and A. vulgaris against the melonworm Diaphania hyalinata (Linnaeus, 1758) (Lepidoptera: Crambidae) larvae, a pest of Cucurbitaceae, and their selectivity for fire ant Solenopsis saevissima (Smith) (Hymenoptera: Formicidae) and jataí bee Tetragonisca angustula (Latreille) (Meliponinae). The plants were grown in a greenhouse with mineral fertilization and were used...

Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner) Rev. Bras. entomol.
Nawaz,Ahmad; Ali,Habib; Sufyan,Muhammad; Gogi,Muhammad Dildar; Arif,Muhammad Jalal; Ranjha,Mazhar Hussain; Arshid,Muhammad; Waseem,Muhammad; Mustafa,Tariq; Qasim,Muhammad; Rizwan,Muhammad; Zaynab,Madiha; Khan,Khalid Ali; Ghramh,Hamed A..
ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to evaluate against this pest. The entomopathogenic viruses like nuclear polyhedrosis virus (NPV), a member of baculoviruses, can be the potential candidates for better control against ABW. The present study was conducted to assess the comparative efficacy of NPV and Spinosad 240SC (with the concentration of 250 mL · ha-1) against ABW in the controlled environment. The ABW was treated with different...

Crop Choice, Non-Target Pest Levels, Yield Loss and Their Effect on Insecticide Use in South Dakota AgEcon
McDonald, Tia Michelle; Keating, Ariel Ruth; Fausti, Scott W.; Li, Jing; Lundgren, Jonathan G..
Agriculturally, South Dakota is a unique state possessing the highest rate of adoption for genetically modified crop varieties. In 2009 ninety-six percent of corn acres planted in South Dakota were genetically modified compared with eighty-five percent nationally (Economic Research Service). Additionally, South Dakota has seen a dramatic increase in the number of acres treated with insecticide over the past 20 years. These two situations taken together seem to be counterintuitive. Some genetically modified varieties, such as Bt corn, are equipped with genetic defenses so that they can protect the plant from target pests. Intuitively, one would expect to see a decrease in insecticide use as adoption of genetically modified varieties increase. Recent...

Effect of ivermectin on the life cycle and larval fat body of Culex quinquefasciatus BABT
Alves,Stenio Nunes; Serrão,José Eduardo; Mocelin,Giovani; Melo,Alan Lane de.
The present work investigated the behavior, survival rate and lethal effect of 1.5 ppb ivermectin on Culex quinquefasciatus larvae, based on morphological and biological parameters, and possible alterations of their fat body. Changes in the number of eggs/egg mass and length of the larval stage were investigated. For this experiment, 600 larvae of 3rd and 4th instars of the mosquito were tested. The laid eggs were separated and the hatched larvae were counted. Some larvae submitted to 1.5 ppb ivermectin solution were used to prepare samples for histological study. Results obtained showed that ivermectin in a concentration of 1.5 ppb caused paralysis to the larvae with a mortality rate of 73.38%, mobilization of substances stored in the fat body and...

Effect of spinosad bait against Ceratitis capitata (Wied.) and Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) in laboratory Neotropical Entomology
Raga,Adalton; Sato,Mário E..
Laboratory studies were conducted to determine the mortalities caused by spinosad in Ceratitis capitata (Wied.) and Anastrepha fraterculus (Wied.). Spinosad formulated bait, diluted in water, was compared with baits of malathion, trichlorfon, fenthion and deltamethrin. The lethal time increased for C. capitata (medfly) adults fed in lower concentrations of spinosad. The LT50 values for C. capitata were estimated in 106, 126 and 154 min for 80, 8 and 4 ppm, respectively. No differences at LT50 were observed for different ages, 2-3d, 3-5d and 5-7d old C. capitata exposed to 80 ppm. Both fruit fly species presented similar pattern of survival when treated with spinosad at 80 ppm. In general, fenthion and trichlorfon showed LT50 values lower than spinosad for...

Effects of Insecticide Seed Treatments Impove Sugarbeet Storability NWISRL
Strausbaugh, C.A.; Rearick, E.; Eujayl, Imad A.; Foote, P..
Sucrose loss in sugarbeet storage is a concern for all roots, but particularly those stored under ambient conditions. In order to control or suppress insect issues in sugarbeet production and consequently improve root storability, two neonicotinoid seed treatments, Poncho Beta (60 g a.i. [active ingredient] clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seeds) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seeds), were used to produce roots from four commercial sugarbeet cultivars grown in Declo, ID. At harvest, eight-beet samples from each cultivar-treatment combination were collected and placed inside an outdoor pile. Samples were removed on approximately 30-day intervals beginning on December 6 and 8 in 2008 and 2009,...
