Interação de Genótipos de Abobrinha Italiana com Inseticida no Controle da Broca das Cucurbitáceas Diaphania nitidalis Cr.
[Interaction of squash genotypes with insecticide on the control of the pickleworm Diaphania nitidalis Cr.]
Anais da Sociedade Entomológica do Brasil 27 (4), 621-626
Abstract: Resistance to the pickleworm Diaphania nitidalis Cr. on squash genotypes Cucurbita pepo L. was evaluated in the field. The number of fruits and the percentage of the bored fruits were observed on the genotypes Caserta AG-202, HE-303, Clarice AG-772, Lita-186, Duda, and Novita. Genotype Duda produced the greatest number of fruits (33 fruits/plot). Genotype Lita-186 was the most preferred with the greatest number of damaged fruits (3.6), while genotype Duda was not damaged. Genotypes AG-202, Lita-186 and Duda, were selected to observe the interaction of squash genotypes with deltamethrin insecticide 25 CE to control the pickleworm. Genotype Duda was the most productive (35 fruits/plot) and least damaged one (0.35%), confirming the results of the 1st experiment. Genotypes AG-202 and Lita-186 were greatly preferred by D. nitidalis (2.7 and 6.3%, respectively).
