Effect of diet on male reproductive tract of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae).
The morphology and histology of the reproductive tract of males of the predator Podisus nigrispinus (Dallas) fed on different diets were studied. P. nigrispinus was fed on diets of: larvae of Alabama argillacea (Hübner), Tenebrio molitor L., Musca domestica L., and an artificial diet. The male reproductive tract, independent of diet, showed testes with intense red coloration in a compact, circu...
متن کاملToxic effects of the neem oil (Azadirachta indica) formulation on the stink bug predator, Podisus nigrispinus (Heteroptera: Pentatomidae)
This research investigated the effects of neem oil on mortality, survival and malformations of the non-target stink bug predator, Podisus nigrispinus. Neurotoxic and growth inhibitor insecticides were used to compare the lethal and sublethal effects from neem oil on this predator. Six concentrations of neem oil were topically applied onto nymphs and adults of this predator. The mortality rates ...
متن کاملDevelopment and reproduction of Podisus distinctus (Heteroptera: Pentatomidae) fed on larva of Bombyx mori (Lepidoptera: Bombycidae).
Biological control has been reducing the use of chemical products against insect pests, especially predatory Pentatomidae. Species of this group can present high variations in their life cycle as a result of their diet. Thus, the objective of this research was to study nymph development and reproduction of Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) fed on Bombyx mori L., 1758 (...
متن کاملPheromone Blends of Predaceous Bugs (Heteroptera: Pentatomidae: Podisus spp.)
Male predaceous stink bugs (Pentatom idae: A sopinae) in the genus Podisus release longrange a ttrac tan t pherom ones from a pair o f hypertrophied glands opening underneath the wings. Pherom one com positions are reported for four additional Podisus spp.: two N eotropi cal species (P. connexivus and an undeterm ined Podisus sp.), and two N earctic species (P. placidus and P. mucronatus). M a...
متن کاملAssessing Biochemical Fitness of Predator Podisus maculiventris (Heteroptera: Pentatomidae) in Relation to Food Quality: Effects of Five Species of Prey
Preferences of female predators for various species of prey may not correlate with nutritional value of the prey, notably with regard to resulting rates of reproduction in the female predator. This study assessed the biochemical status of adult female Podisus maculiventris (Say) as affected by prey species. Colony-reared females were fed one of Þve species of natural or factitious prey: beet ar...
