Petri Dishes

Females of Cotesia flavipes (Cam.) were individually introduced into Petri dishes containing one larva of its host Diatraea saccharalis (Fabr.). Each C. flavipes female was allowed to oviposit once or twice in the same larva. Time of emergence of larvae and adults, sex-ratio, number of non-viable larvae and pupae, and longevity of adults of C. flavipes were recorded. Data revealed that two successive ovipositions in the host did not affect sex-ratio, but increased number of parasitoids and number of non-viable larvae and pupae.

Avaliou-se a resistência de genótipos de sorgo (Sorghum bicolor) a Contarinia sorghicola (Coq.) e Diatraea saccharalis (Fabr.) e sua influência sobre parasitóides. Foram realizados ensaios em duas épocas de plantio, anotando-se o número de insetos (pragas e parasitóides) e calculando-se a percentagem de parasitismo. O genótipo AF-28 destacou-se como o mais resistente às duas espécies pragas, ocorrendo o inverso com o TX-2567; as maiores percentagens de parasitismo de C. sorghicola por Tetrastichus sp. (Hymenoptera: Eulophidae) ocorreram em BR-501 (36,7%) e AF-28 (20,0%); as maiores percentagens de parasitismo de D. saccharalis por Cotesia flavipes (Cam.) (Hymenoptera: Braconidae) foram observadas em BR-601 e 3DX-57 (50 e 40%).
