Parasitism and predation of stink bug (Heteroptera: Pentatomidae) eggs in Georgia corn fields.
Nezara viridula L. and Euschistus servus (Say) are the predominant species of phytophagous stink bugs on corn, Zea mays L., in Georgia. Oebalus pugnax pugnax (F.) occurs in relatively low numbers, and the predatory stink bug Podisus maculiventris (Say) is commonly found. Limited information is available on natural biological control of these four stink bug species in Georgia corn fields; there...
متن کاملEffect of host kairomones and oviposition experience on the arrestment behavior of an egg parasitoid.
Chemical residues left by walking adults of the southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae) induce arrestment behavior in the egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae) leading to prolonged periods of walking on contaminated areas and to systematic return to the stimulus after encountering the treatment borders. In this study, we quan...
متن کاملHost Chemical Footprints Induce Host Sex Discrimination Ability in Egg Parasitoids
Trissolcus egg parasitoids, when perceiving the chemical footprints left on a substrate by pentatomid host bugs, adopt a motivated searching behaviour characterized by longer searching time on patches were signals are present. Once in contact with host chemical footprints, Trissolcus wasps search longer on traces left by associated hosts rather than non-associated species, and, in the former ca...
متن کاملThe effect of noise on sexual behaviour of the southern green stink bug Nezara viridula
Stink bugs of the pentatomid family communicate using substrate-borne vibrational signals transmitted through host plants. Specific signal length and repetition rate are critical for mate recognition and are susceptible to masking by simultaneous conspecific and congeneric signals. We tested whether overlapping conspecific signals interrupt Nezara viridula (L.) sexual behaviour with playback of...
متن کاملPossible egg positioning and gluing behavior by ovipositing southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae).
From March 2002 to January 2004, a colony of southern green stink bug, Nezara viridula (L.), was kept in the laboratory, and its oviposition behavior was observed. During oviposition, soon after the egg is expelled, the female touches the egg mass with the dorsal surface of the last tarsomere; this movement of one leg of the hind pair occurred once. This small component of the oviposition behav...
