“…Host male attractant pheromone (E)-2-Hexenyl (Z)-3-Hexenoate Attraction in field, increased parasitism [34][35][36] Ooencyrtus telenomicida [86] 4 Psyche through the combined exploitation of cues that are directly and indirectly related to host eggs [7,8,13,14]. First, parasitoids may detect volatiles from nontarget instars of the host, that is, adults or juveniles, to reach the vicinity of the host eggs (infochemical detour sensu Vet & Dicke [8]), eventually enabling them to pin-point eggs using additional long-and/or short-range cues.…”

“…Exploitation of pheromones and/or allomones from host adults has been demonstrated for both Platygastridae [28,[30][31][32][33] and Encyrtidae [34][35][36][37][38] (Table 1). These stimuli provide indirect information on the presence of the host community, leading the wasp female to the vicinity of host eggs.…”

“…Males of R. clavatus emit an aggregation pheromone, composed of a blend of three compounds that attract adults of both sexes and nymphs. One compound, (E)-2-hexenyl (Z)-3-hexenoate, attracts females of O. nezarae and resulted in higher parasitism in treated fields compared with untreated fields [35,36]. This tiny parasitoid has the remarkable ability to fly just above the plant canopy in nonhost habitat, while exploiting the above cues to reach the host habitat [37], although the exact flight mechanisms are unknown.…”

Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera. Several species of heteropteran egg parasitoids are or may be important for biological pest control. Successful parasitism of insect herbivores by insect parasitoids arises through several phases of host searching, which lead female wasps to the vicinity of, or in contact with, their hosts. During the host location process, females encounter and explore a variety of stimuli, among which chemical cues (i.e., semiochemicals or infochemicals) play a pivotal role. Female parasitoids are under selection pressure to efficiently invest their limited time on the location and exploitation of host-derived stimuli. In general, the levels of reliability and detectability of a particular stimulus are inversely correlated. Female parasitic wasps adopt differing strategies to solve this dilemma. In this paper we focus on the various host selection strategies employed by heteropteran egg parasitoids and possible means whereby the chemically mediated behavior of these wasps may be exploited to enhance biological pest control.

: This study was conducted to determine pheromone trap type and height in forecasting populations of R. clavatus in soybean fields using pheromone. The most effective pheromone trap type and height in forecasting populations of R. clavatus were fish trap and 60 cm above ground. Ratio of R. clavatus adults female and male in soybean field was 1.5 to 1 and Piezodorus hybneri was also attracted to the aggregation pheromone trap of R. clavatus. Attractiveness of two stink bug species caught on synthesis pheromone of R. clavatus was surveyed with imported production and synthesized production. Imported pheromone attracted only adult of R. clavatus, but synthesized pheromone attracted both adult of R. clavatus and P. hybneri. Change of population of R. clavatus was observed using pheromone trap and sweeping method in soybean field. Adults of R. clavatus occurred from early August and the population reached its peak in early September when pheromone trap was used. In case of sweeping method, its fluctuation pattern was similar to that of pheromone trap.

The contents of five pheromone components and the physiological conditions of wild male and female Riptortus pedestris attracted to bait males during non-diapause (from early July to early September) and diapause (from midSeptember to mid-October) periods in the field were examined. Although tetradecyl isobutyrate (14:iBu), an essential pheromone component, was detected in males attracting conspecific individuals, this component was not detected in almost all males attracted to bait males. This indicated that the attracted males are not attractive to conspecific individuals unlike bait males. During non-diapause, (E)-2-hexenyl (E)-2-hexenoate and (E)-2-hexenyl (Z)-3-hexenoate, which are synergistic components of the pheromone, were detected in most males. On the other hand, these components were not detected in most of the males during diapause, indicating that the function of these two components in the attractiveness of males might be related with the sexual communication mechanism. (E)-2-hexenyl hexanoate was detected in almost all males and females attracted to bait males. The physiological conditions were similar between adults attracted to bait males during non-diapause and diapause. Most of the attracted adults had little or no food in their stomachs. This suggested that male-attracted adults of R. pedestris are starved and are searching for suitable host plants.
