Aptitud biológica de poblaciones de Bemisia tabaci (Gennadius) Biotipo B (Hemiptera: Aleyrodidae) con diferente susceptibilidad al insecticida thiametoxam Neotropical Entomology
Campuzano-Martínez,Aidee; Rodríguez-Maciel,J Concepcion; Lagunes-Tejeda,Ángel; Llanderal-Cázares,Celina; Terán-Vargas,Antonio P; Vera-Graziano,Jorge; Vaquera-Huerta,Humberto; Silva-Aguayo,Gonzalo.
In two field-collected populations of de Bemisia tabaci (Gennadius) B biotype previously selected with the neonicotinoid insecticide thiamethoxam (NEO-R, NEO-N), and a population susceptible to insecticides (SUSC), the level of response to the insecticide thiametoxam, as well as the life and fertility tables were determined. At LC95, the NEO-R population showed a resistance ratio (RR95) value of 8.8-fold, an intrinsic rate of increase (r m) of 0.72. The fitness of the NEO-R and NEO-N populations in relation to the SUSC was 1.5 and 2.0, respectively. The RR95 value for NEO-N was 1.9-fold; it's r m value was 0.082, while in the SUSC population was 0.041. The developmental time of egg and adult were longer in NEO-R population, while the nymph and pupa lasted...

Imidacloprid impact on arthropods associated with canopy of common beans Neotropical Entomology
Marquini,Flávio; Picanço,Marcelo C.; Guedes,Raul N.C.; Ferreira,Paulo S.F..
The present work aimed at assessing the temporal and spatial effect of applying the insecticide imidacloprid on the arthropod community associated with the canopy of common beans (Phaseolus vulgaris). About 2 ha of bean field was divided into two adjacent fields subjected to the same crop management practices except for insecticide application. Imidacloprid 700 GrDA (147 g a.i./ha) was applied to 20-day old plants. Three transects were extended from the mid-part of the sprayed area to the mid-part of the non-sprayed area. Nine sampling points 10 m apart were established in each transect. Arthropods were sampled from the plant canopy before and 3, 8, 14, 22, 29 37 and 44 days after insecticide application. There was a strong temporal effect of the...
