Comparison of susceptibility of pest Euschistus servus and predator Podisus maculiventris (Heteroptera: Pentatomidae) to selected insecticides.
Susceptibility of the brown stink bug, Euschistus serous (Say), and the spined soldier bug, Podisus maculiventris (Say), to acetamiprid, cyfluthrin, dicrotophos, indoxacarb, oxamyl, and thiamethoxam, was compared in residual and oral toxicity tests. Generally, susceptibility of P. maculiventris to insecticides was significantly greater than or not significantly different from that of E. servus....
متن کاملLife history and cost analysis for continuous rearing of Podisus maculiventris (Say) (Heteroptera: Pentatomidae) on a zoophytophagous artificial diet.
The impact of a zoophytophagous, insect-free artificial diet upon the developmental rate, life table parameters, and fertility table parameters was examined over 11 consecutive generations for domesticated and wild colonies of Podisus maculiventris (Say) (Heteroptera: Pentatomidae). This study showed that the developmental time, preoviposition period, fecundity, and nymphal survival improved in...
متن کاملThe control of Malpighian tubule secretion in a predacious hemipteran insect, the spined soldier bug Podisus maculiventris (Heteroptera, Pentatomidae).
Spined soldier bugs, Podisus maculiventris, are heteropteran insects that feed voraciously on other insects, particular the soft bodied larval forms of Lepidoptera and Coleoptera. The response of P. maculiventris Malpighian tubules (MTs) to serotonin and known diuretic and antidiuretic peptides has been investigated, and is compared with that of MT from the hematophagous and phytophagous hetero...
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...
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).
