Biologia de ninfas e adultos do percevejo-verde em estruturas reprodutivas de algodoeiro

Abstract

The objective of this work was to evaluate the biology of nymphs and adults of the green stink bug in cotton reproductive structures. The tested foods were: standard diet, containing green-bean pods, raw peanuts, and privet fruits; green soybean pods; soybean seed; cotton floral buds; and cotton bolls and seeds. The biological parameters evaluated were: nymphal developmental stage and survival; longevity of females and males; percentage of females in oviposition; prevoviposition and oviposition periods; total number of eggs per female, and viability of eggs. Nymphs fed on cotton reproductive structures died in the second or third instar. Adults fed with cotton floral bud and seed do not reproduce; however, reproduction occurs when green stink bug adults are fed cotton bolls, indicating the adaptability capacity of the species in the reproductive stage of cotton.
