Abstract

The objective of this work was to study the effects of the leaf blades and present trichomes in squash leaves (Curcubita pepo) on the oviposition of . D. hyalinata. Two bioassays were conducted: one of free choice and another of confinement. The trichomes were counting in leaf blades of 10 leaves. In the bioassay of free choice the oviposition was larger in abaxial leaf blade than in the adaxial, which was only verified in leaves in natural position in the confinement bioassay. It was verified in the bioassay of free choice increase of the oviposition when the position of the leaf blades was inverted. The abaxial leaf blade presented larger total number of non-glandular trichomes and of glandular trichomes type P than the adaxial leaf blade. The adaxial leaf blade, on the other hand, presented larger number of glandular trichomes types C and the total of glandular trichomes that to the abaxial leaf blade.
