Resumo: | The objective of this study was to evaluate the residual and sublethal effects of the insecticides acetamiprid (0.05 g a.i./L), lufenuron (0.04 g a.i./L), imidacloprid (0.14 g a.i./L), novaluron (0.02 g a.i./L), triflumuron (0.14 g a.i./L), and pyriproxifen (0.1 g a.i./L) on adults from the maternal generation of Trichogramma pretiosum, as well as their subsequent effects on the F1 and F2 generations. Eggs of Anagasta kuehniella were glued to paper cards, UV-killed, and dip-treated in insecticide solutions. Next, the eggs were exposed for parasitism 1, 24, and 48 h after treatment, maintained that way for 24 h under controlled conditions (24 ± 2° C, 70 ± 10% relative humidity, 12-h photophase), until the emergence of the parasitoids. The insecticide toxicity was calculated based on the longevity and parasitism capacity of the maternal generation, as well as on the emergence rate, sex ratio, longevity, and parasitism capacity of the F1 and F2 generations. The insecticides were toxicologically classified according to IOBC. Pyriproxifen was slightly harmful (class 2) for the parasitism capacity of T. pretiosum maternal and F1 generation females. Novaluron was slightly harmful for the emergence rate of the F1 generation. Acetamiprid, imidacloprid, lufenuron, and triflumuron were harmless (class 1) to T. pretiosum. |

L) en la generación parental de adultos de Trichogramma pretiosum, tanto como sus efectos posteriores sobre las generaciones F1 y F2. Huevos de Anagasta kuehniella adheridos con goma árabe a cuadros de cartón fueron sacrificados con luz UV y tratados por inmersión en las soluciones de insecticida. Luego, se expusieron al parasitismo 1, 24 y 48 horas después del tratamiento durante 24 horas bajo condiciones controladas (24 ± 2°C, humedad relativa 70 ± 10%, 12-h fotofase) hasta la emergencia de los parasitoides. Se calculó la toxicidad de los insecticidas basados en la longevidad y la capacidad de parasitismo de las hembras de la generación materna, así como en la tasa de emergencia, la proporción de sexos, la longevidad y la capacidad de parasitismo de las generaciones F1 y F2. Los compuestos se clasificaron según la IOBC. Piriproxifen fue levemente perjudicial (clase 2) para la capacidad de parasitismo de las hembras maternales y la generación F1 de T. pretiosum. Novaluron fue levemente perjudicial para la emergencia de la generación F1. Acetamiprid, imidacloprid, lufenurón y triflumurón fueron inocuos (clase 1).Sociedad Colombiana de Entomología2019-11-26T16:15:23Z2019-11-26T16:15:23Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCARVALHO, G.
