Provedor de dados: 32
Autores: Sosa Hernández, Claudia María.
La medición y estimación de variables que permitan visualizar  la dinámica de las poblaciones plaga en función del medio ambiente y sus repercusiones en la sanidad de las plantas, es una de las herramientas de decisión en las que los productores se pueden apoyar para la implementación de programas de manejo integrado. Por ello se realizó la comparación de la sensibilidad de tres métodos de cuantificación para la detección de  zoosporas de Phytophthora drechsleri en muestras de agua. Se determinó que es posible detectar cantidades más pequeñas de zoosporas mediante la realización de pruebas ELISA que con la cuantificación en hematocitómetro o la siembra en medio de cultivo. Con los datos de absorbancia obtenidos a partir de pruebas ELISA se realizaron...

The activity of Metarhizium anisopliae and Beauveria bassiana towards eggs and larvae of Tuta absoluta (Meyrick) was evaluated. Our data showed that the isolates were pathogenic to both developmental stages tested and the eggs were more susceptible than the 1st instars. The isolates URPE-6 and URPE-19 of M. anisopliae were more pathogenic to eggs and larvae, respectively. The compatibility of these two isolates with the insecticides chlorfenapyr, spinosad, indoxacarb, abamectin, and neem were evaluated. Spinosad and indoxacarb were compatible with the two M. anisopliae isolates in all tested concentrations. At the average recommended concentration, chlorfenapyr was compatible to URPE-6 and abamectin to UFPE-19. The use of entomopathogenic fungi associated...

Effect of two solanaceous plants on developmental and population parameters of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
Provedor de dados: 82
Autores: Pereyra,Patricia C.; Sánchez,Norma E.
Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta related with host-plant suitability. Larval developmental time, pupal weight, mean fecundity and an index of host-plant quality (IPQ = pupal weight / frass weight) were estimated. Age-specific survivorship and fecundity life tables were constructed in the laboratory to evaluate the following populational parameters: net reproductive rate (Ro), intrinsic rate of increase (r) and generation time (T). Larval developmental time was shorter and pupal weight was higher...

Chrysoperla externa (Neuroptera: Chrysopidae) and Utetheisa ornatrix (Lepidoptera: Arctiidae) on organically grown Crotalaria juncea (Fabaceae)
Provedor de dados: 87
Autores: Costa,M.A.; Tavares,W.S.; Pereira,A.I.A.; Cruz,I.; Serrão,J.E.; Zanuncio,J.C.
Chrysoperla externa (Neuroptera: Chrysopidae) larvae can avoid foraging on plants of Crotalaria juncea (Fabaceae) after the issuance of floral buds, when the prey of Utetheisa ornatrix (Lepidoptera: Arctiidae) incorporate toxic pyrrolizidine alkaloids from this plant. This reduces the predation and favors increasing the number of adults and eggs of this defoliator on crops of this plant. The aim of the present paper was to evaluate some biological and ecological aspects of C. externa and U. ornatrix on the organic crop of C. juncea in the EMBRAPA Maize and Sorghum in Sete Lagoas, Minas Gerais State, Brazil. Chrysoperla externa and U. ornatrix were more abundant in the vegetative and flowering stages of C. juncea, respectively, with caterpillars of this...

Pesticide Use and IPM Adoption: Does IPM Reduce Pesticide Use in the United States?
Provedor de dados: 31
Autores: Maupin,   Jason; Norton,   George W.
In 2001, the United States General Accounting Office issued a report entitled “Management Improvements Needed to Further Promote Integrated Pest Management.”  This report documents that overall agricultural pesticide usage increased from 1992 to 2000 while the use of the most toxic levels of pesticides have decreased.  The USDA suggests that these changes in pesticide use could have been caused by integrated pest management (IPM) adoption.   However, the GAO maintains that there is not enough evidence to support this claim.  This paper contributes to this debate by estimating the relationship between pesticide use and IPM practices adopted for number of commodities across the nation from 1996 to 2005.  The paper exploits an aggregated data set that...

LABORATORY AND FIELD EVALUATION OF A CYPERMETHRIN-BASED INSECTICIDE FOR THE CONTROL OF ALPHITOBIUS DIAPERINUS PANZER (COLEOPTERA: TENEBRIONIDAE) AND ITS IN-VITRO EFFECTS ON BEAUVERIA BASSIANA BALS. VUILL. (HYPOCREALES: CORDYCIPITACEAE)
Provedor de dados: 89
Autores: Oliveira,DGP; Cardoso,RR; Mamprim,AP; Angeli,LF.
ABSTRACT The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the effect of a new product (cypermethrin-6%) under laboratory and field conditions and assessed its in-vitro compatibility with the fungus Beauveria bassiana (Unioeste 4 isolate). Its efficiency in dry powder and wettable powder formulations was also assessed in the laboratory through comparison with a similar insecticide (cypermethrin-5%) at five different concentrations. The field assays were conducted...

Migration and dispersal of Anthonomus grandis (Coleoptera: Curculionidae) in South America
Provedor de dados: 99
Autores: Stadler,Teodoro; Buteler,Micaela.
This study discusses the dispersal of Anthonomus grandis Boheman, the cotton boll weevil, in Argentina, Brazil, Paraguay and Bolivia, exploring the ecological and physiological factors that have made the dispersal and establishment of this insect in South America so successful. The boll weevil's phenotypic plasticity is represented by its flexible developmental time, its multivoltine life cycle with several overlapping generations, its capacity to feed on pollen from diverse botanical families as well as from non pollen food sources and its ability to migrate and disperse aided by winds. These characteristics make it a key pest for cotton. Probable overwintering «hot spots» for the boll weevil were identified in Misiones-Argentina, where large numbers of...

Provedor de dados: 42
Autores: BARONIO,CLÉBER A.; BERNARDI,DANIEL; PARANHOS,BEATRIZ A.J.; GARCIA,FLÁVIO R.M.; BOTTON,MARCOS.
Abstract To provide alternatives to the use of spraying synthetic insecticides in C. capitata management, was evaluated the effect of “attract and kill” toxic baits on population suppression of C. capitata in three commercial areas producing table grapes. Toxic baits of Gelsura™ (4.5 L ha-1) and Success™ 0.02 CB (4.0 L ha-1) resulted in lower population levels of C. capitata adults in monitoring traps after five sequential applications at weekly intervals during the maturation period of the grapes when compared with control plots with or without insecticidal spray. In addition, plots with Gelsura™ and Success™ 0.02 CB applications showed a significant reduction in damage (%) by C. capitata on grape berries and grape bunches when compared with control plots...
