Pheromone 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 کاملDynamics and seasonal abundance of stink bugs (Heteroptera: Pentatomidae) in a cotton-soybean ecosystem.
Two soybean varieties (early-maturing group V and late-maturing group VII) and two cotton varieties (conventional and transgenic (Bt) were grown in adjacent replicated large field plots (approximately 0.1 ha each) at two locations for 3 yr. The dynamics and relative abundance of phytophagous stink bugs within these two crops were observed. The most abundant pentatomid species in both crops for ...
متن کاملSpatiotemporal patterns and dispersal of stink bugs (Heteroptera: Pentatomidae) in peanut-cotton farmscapes.
In the southeast United States, a field of peanuts, Arachis hypogaea L., is often closely associated with a field of cotton, Gossypium hirsutum L. The objective of this 4-yr on-farm study was to examine and compare the spatiotemporal patterns and dispersal of the southern green stink bug, Nezara viridula L., and the brown stink bug, Euschistus servus (Say), in six of these peanut-cotton farmsca...
متن کاملResonance in herbaceous plant stems as a factor in vibrational communication of pentatomid bugs (Heteroptera: Pentatomidae).
Pentatomid bugs communicate using substrate-borne vibrational signals that are transmitted along herbaceous plant stems in the form of bending waves with a regular pattern of minimal and maximal amplitude values with distance. We tested the prediction that amplitude variation is caused by resonance, by measuring amplitude profiles of different vibrational pulses transmitted along the stem of a ...
متن کاملThestral incognitus, a new genus and species of Pentatomidae from Chile (Heteroptera: Pentatomidae: Pentatominae: Carpocorini).
Thestral incognitus, new genus and species of Pentatomidae (Pentatominae: Carpocorini) is described from central Chile. The relationships among this new genus and other South American genera are discussed. Also, similarities are noted between Thestral and the Australian genus Poecilotoma. Poecilotoma is tentatively placed in the Carpocorini. A key to aid in the recognition of the genera of Chi...
