Halyomorpha halys Stål, the brown marmorated stink bug (Hemiptera: Pentatomidae), is an invasive pest with established populations in Oregon. The generalist feeding habits of H. halys suggest it has the potential to be a pest of many specialty crops grown in Oregon, including hazelnuts, Corylus avellana L. The objectives of this study were to: 1) characterize the damage to developing hazelnut k...

Adults of the tomato stink bug, Arvelius albopunctatus (De Geer), from pasture lands at Londrina, Paraná state (latitude 23º 18' S; longitude 51º 09' W) and of Dichelops furcatus (F.) (Heteroptera: Pentatomidae) from field crops at Cruz Alta, Rio Grande do Sul state (latitude 28º 38' S; longitude) southern Brazil were parasitized by Hexacladia smithii Ashmead , which are set as new host records...

Some species of the Heteroptera (Hemiptera) suborder are great agricultural importance, mainly as pests, and their control is often necessary. The use Bacillus thuringiensis, an entomopathogenic bacterium normally extracted from soil used in biological control, alternative to chemical these insects. Mortality tests must be carried out order select determine a viable toxic strain, but currently ...

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...

Egg parasitoids of the stink bug Edessa meditabunda (F) were studied on rattlepod Crotalaria spectabilis used in soybean crop rotation in Campo Novo do Parecis, Mato Grosso state, central western Brazil. Seven species of parasitoids were found: two Encyrtidae, one Eurytomidae, and four Platygastridae. The occurrence of Trissolcus euchisti (Ashmead) and Trissolcus elimatus Johnson (Platygastrida...

The rice stink bug [Oebalus pugnax (F.)] is one of the important pests commonly found in Arkansas rice fields. When outbreaks in fields reach critical levels, an insecticide application is an option. Pyrethroid and organophosphate insecticides usually give excellent contact mortality, but both groups lack any significant residual activity. Two insecticides, dinotefuran and clothianidin, were te...
