Caging experiments with pistachio fruits by Bolkan et al (1984) found an increase in the number of fruits dropped from 3.8% in the control protected from bug feeding to 32.9% in infructescences subjected to 48 hours of feeding by a single L. clypealis. Sometimes an exudation of gum from the feeding puncture occurs, similar to the drops of resin described by Flores Lara (1986) on conelets of pinyon pine after feeding by Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae).…”

The type of injury and amount of damage to the fruits and seeds of physic nut (Jatropha curcas L., Euphorbiaceae) caused by two species of fruit feeding true bugs, Pachycoris klugii Burmeister (Heteroptera: Scutelleridae) and Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae), and the flower feeding true bug, Hypselonotus intermedius Distant (Heteroptera: Coreidae), were assessed using field cages. The parameters analysed were infructescence, fruit, seed and seed kernel weight, seed length, fruit and seed abortion, seed malformation and oil and protein content of the seed kernels. All three species reduced overall yield. The two members of the fruit feeding guild led to premature fruit abortion and malformed seeds. Reduction of fruit, seed and seed kernel weight as well as seed length could be expressed as linear regressions of adult population densities. The oil content of the seeds was slightly reduced by the bugs, but protein content remained unchanged. Damage increased with the developmental stage of the larvae. Whereas adult L. zonatus of both sexes produced more damage than the nymphs, female P. klugii caused less damage than nymphs, and male P. klugii no significant damage at all. H. intermedius is a pollinator of this entomogamous plant. At high densities, however, it reduced the number of fruits maturing.

“…In California, C. hilaris is one of a group of hemipteran species that cause direct crop damage to pistachio (Bolkan et al 1984, Rice et al 1985, an exotic crop that has increased greatly in crop acreage and value since the 1980s (Anonymous 2010). When hemipteran damage to pistachio nuts was Þrst reported, species were often simply grouped as small bugs (Miridae and Rhopalidae) and big bugs (Pentatomidae and Coreidae) (Rice et al 1985, Michailides et al 1987, based not only on their physical size but on their seasonal occurrence and type of crop damage.…”

Life history parameters were established under controlled laboratory conditions for the green stink bug, Chinavia hilaris (Say) (= Acrosternum hilare), to improve pest control in pistachios in California. Parameters measured and calculated included survival and development at seven constant temperatures (ranging from 15 to 35 degrees C), development time, upper and lower development thresholds, thermal constants, fecundity, generation time, net reproductive rate, and intrinsic rate of increase. C. hilaris did not complete development at 15 and 35 degrees C. Within the range of 20-27.5 degrees C, development time decreased linearly with temperature; it increased again at 30 degrees C. The lower threshold was calculated by linear methods to be 12.3 degrees C, and the thermal constant was calculated to be 588 degree days. Fastest development was recorded at 27.5 degrees C, whereas greatest survival was observed at 22.5 degrees C. At 27.5 degrees C, mean fecundity was 53.5 eggs per female, mean generation time was 74.4 d, net reproductive rate was 20.09, and intrinsic rate of increase was 0.04. Use of a nonlinear model yielded estimates of 13.2, 28.4, and 33.4 degrees C, for the lower threshold, optimum temperature, and upper threshold, respectively. Results were compared with similar studies and interpreted in the light of pest management needs in pistachio. Increased emphasis on monitoring and management ofoverwintering sites and early-season migration are recommended.

“…Of the three subfamilies, the Coreinae is by far the largest and contains most of the economically important species. In North America, Leptoglossus phyllopus (Linnaeus) is a serious pest of various crops (Mead 1971, Bolkan et al 1984, Mitchell 2006. Species of the genus Chelinidea often become pests of ornamental and rangeland cacti (Opuntia spp.…”
