The subfamily Pentatominae is the most diverse within Pentatomidae, with about 120 genera and 680 species recorded in Neotropics. Euschistus Dallas, 1851 Glyphepomis Berg, 1891 Banasa dolabrata Thomas, 1988, B. peruana 1990, testacea setigera Kormilev & Pirán, 1952, taurulus 1878 are for first time Paraguay; two monotypic genera, Berecynthus Stål, 1862 Nocheta Rolston, 1980, Bolivia Ecuador...

Determining relative strengths of trophic links is critical for ranking predators for conservation biological control. Molecular gut-content analysis enables ranking by incidence of prey remains in the gut, but differential digestive rates bias such rankings toward predators with slower rates. This bias can be reduced by indexing each predator’s half-life to that of the middle-most half-life in...

Nezara viridula L. (Hemiptera: Pentatomidae) is a serious pest of macadamia nuts, Macadamia integrifolia, in Hawaii. Using ruthenium red dye to stain stink bug feeding probes, feeding activity was determined for nuts of various maturity levels harvested from the tree and off the ground throughout the growing season in Þve commercial cultivars. Damage occurred in the tree and on the ground durin...

According to geographical distribution, Nezara viridula (Heteroptera: Pentatomidae) can be found across tropical, subtropical, and temperate regions and this pattern is assumed to reflect differences in thermal adaptation, particularly in cold tolerance. Here the lethal temperature (LT) and critical thermal limits (CTL) (thermal tolerance) are examined for N. viridula. The upper LT for N. virid...

Detecting infestations of stink bugs (Heteroptera: Pentatomidae) using pheromones remains problematic, particularly so in the United States for the exotic stink bug, Nezara viridula L., and our native stink bug, Acrosternum hilare (Say). Therefore, we conducted a 2-yr on-farm study to examine the attractiveness and possible cross-attraction of the reported pheromones for N. viridula and A. hila...

The brown marmorated stink bug, Halyomorpha halys (Stål) (BMSB) is an exotic invasive insect originating in East Asia, currently causing significant damage to fruits, vegetables and other crops throughout most of the Mid-Atlantic states of the U.S. It also is a nuisance pest, entering homes in the fall in search of suitable overwintering sites. Two formulations of BotaniGard(®) with a strain of...

The rice stink bug, Oebalus pugnax (Fabricius) (Hemiptera: Pentatomidae: Carpocorini), though graminaceous, discriminates among its numerous host grass species. This could represent a feeding preference, it could be related to host suitability for growth and development. To clarify the role of host grass discrimination, two laboratory studies were conducted: (1) free-choice tests to evaluate pr...
