“…However, he also found that young stems on which ACM had fed shrivelled up and died, indicating the translocation of salivary enzymes along the stolon. The present study detected no differences in stolon length associated with PM feeding, and elsewhere PM feeding damage has been shown to be localised to a small area of plant tissue associated with the stylet lesion (Uyemoto et al 1986;Michailides et al 1987;Schroeder & Clifford 1996). Generally, the younger the buds are when they are attacked, the greater will be the effect on seed yield, and the higher the number of undamaged inflorescences per unit area the higher the total seed yield (Fig.…”

Potato mirid, Calocoris norvegicus, commonly occurs in white clover, Trifolium repens, crops in Canterbury, New Zealand. Its potential to reduce seed yield by feeding injury was investigated in field cage plots in a cv. Huia white clover seed crop. Third to fifth instar nymphs were released at five intensities ranging from 0 to 2 mirids per 5 stolons. Plant growth and inflorescence production were determined by regular measurements of 15-20 tagged stolons per cage. Seed was harvested in late summer and dressed into first and second quality seed for which thousand seed weights were recorded. No differences between plant growth and flowering pattern were observed between treatments, but inflorescence numbers were quadratically reduced as mirid numbers increased. When total plot flowering and yield components were compared, a significant negative quadratic relationship between total inflorescences and first quality seed yield with increasing mirid intensity was demonstrated. For second quality seed yield a negative linear relationship was observed. A positive linear relationship between undamaged inflorescences and total yield per plot was also

“…Small bugs include several species of Miridae and Rhopalidae, most importantly Closterotomus norvegicus (Gmelin), Phytocoris relativus Knight, and Lygus hesperus Knight [6]. These bugs can be abundant early in the season and may cause significant crop loss through epicarp lesions (damage to the outer shell) and fruit drop but cease to cause damage after the shell begins to harden [7,8,9]. The large bugs are composed of species of Pentatomidae and Coreidae, most notably the stink bugs Thyanta pallidovirens (Stål), Chlorochroa uhleri (Stål), and C. sayi (Stål), and Chinavia hilaris Say, and the leaffooted bugs including Leptoglossus zonatus (Dallas) and L. clypealis Heidemann [5].…”

Leptoglossus zonatus is a polyphagous pest found throughout much of the Western Hemisphere. In California, L. zonatus attacks almond, pistachio, pomegranate, and walnut crops, but the seasonal use of and economic damage to these crops varies. To better understand the seasonal changes of L. zonatus populations and to improve monitoring programs in California’s San Joaquin Valley, we caged overwintering adult males and females and then followed the resulting population dynamics over a one-year period. There were three generations over the one-year period, although eggs, nymphs, and adults overlapped among successive generations. From an initial 75 overwintering adult females, there were 1214 egg strands, 16,692 nymphs, and 4900 adults recorded during the one-year period. Depending on the generation, the number of nymphs per egg strand ranged from 11.3 to 14.3; the sex ratio was close to 1:1 with the exception of one female-biased cage; and nymph mortality ranged from 22.0% to 39.5%. Adult females isolated from each generation produced 2.4–5.1 egg strands per female that totaled 41.7–61.7 eggs per female with a 67.1–86.8% successful hatch rate. We find that the adult is the overwintering stage, as more adults (without food provisions) survived the winter compared to medium-sized or large-sized nymphs provided with both food and water. The results are discussed with respect to the development of L. zonatus control and monitoring programs for California’s multi-billion-dollar (US) nut crops.

“…hilaris overwinters in the adult stage near or in the pistachio orchard (K.M.D., unpublished data) and can disperse from its overwintering sites directly to the pistachio tree, where it attacks the young crop as the fruit begins to form in April. For most bug damage, early-season feeding results in piercing of the fruit pericarp and rapid formation of epicarp lesions (i.e., darkened area of the hull; Uyemoto et al 1986, Bostock et al 1987, often followed by the small (Ͻ1 cm) damaged fruit dropping from the cluster Welter 1991, Daane et al 2005). The natural fruit drop of the pistachio tree from April to early May is thought to compensate for much of the fruit loss caused from this early season bug damage (Beede et al 1996).…”

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.
