“…The close relationship between the feeding conditions of R. clavatus males and their release of attractants suggests that the attractants might play a key role in food exploitation. A similar strategy was proposed in the pheromone system of the brown-winged green bug Plautia stali (ϭPlautia crossota stali) Scott (Heteroptera: Pentatomidae) (Shiga and Moriya, 1989) and predatory stink bugs (Aldrich et al, 1976;Sant'Ana et al, 1997). P. stali males attract conspecific males and females (Moriya and Shiga, 1984).…”

Traps baited with dried soybeans and a synthetic aggregation attractant pheromone were more effective than traps baited with synthetic aggregation pheromone alone against the bean bug, Riptortus clavatus. Dried soybeans alone did not attract bean bugs, so this difference was not due to the attractiveness of the dried soybean itself. The known components of the aggregation pheromone were detectable only in extracts of a few individual attracted bugs; however, all the attracted male bugs had (E)-2-hexenyl hexanoate, which has been identified as an alarm pheromone in this species. This component was present in higher amounts in extracts of male or female R. clavatus that had been fed on soybeans than that of starved males or females. In the experiments, the attractiveness of tetradecyl isobutyrate, which is an essential component of aggregation pheromone, was increased by the addition of (E)-2-hexenyl hexanoate. These results suggested that (E)-2-hexenyl hexanoate is one of the components of the attractant aggregation pheromone of R. clavatus and that it may act as a synergistic composition but not a repellent. It is hypothesized that the pheromonal process related to food exploitation in R. clavatus includes positive feedback since attracted bugs stay to feed at sites and continuously release (E)-2-hexenyl hexanoate.

“…crossota stali) Scott (Heteroptera: Pentatomidae), attraction of male and female adults by the pheromone is considered to be effective in the exploitation of food resources (Shiga and Moriya, 1989). A similar strategy was proposed in the pheromone system of Leptoglossus phyllopus (Heteroptera: Coreidae) (Aldrich et al, 1976) and spined soldier bug Podisus maculiventris (Heteroptera: Pentatomidae) (Aldrich et al, 1984;Sant'Ana et al, 1997;Shetty and Hough-Goldstein, 1998). In R. pedestris, it is considered that the attraction of male and female adults by pheromone is related to food exploitation (Yasuda et al, 2007b).…”

The individual variation of R. pedestris males and females in their attractiveness to the same species and the amounts of five pheromone components were examined in field experiments and GC-MS analysis, respectively. The number of adults attracted by a single male varied greatly among the individuals tested. The number of adults attracted was 0.92Ϯ0.12 (meanϮSE/day). Of 64 males examined individually, four attracted three or more adults per day, while 12 males attracted only 0.5 adults or fewer per day and 14 individuals attracted no adults. The five pheromone components also differed greatly among those males. As for tetradecyl isobutyrate (14:iBu), which is thought to be an essential component of the pheromone, it was apparently detected from 46 males while eight had only a low amount of 14:iBu and ten had no 14:iBu. Some of the males had 14:iBu without having (E)-2-hexenyl (E)-2-hexenoate (E2-6:E2Hx) and (E)-2-hexenyl (Z)-3-hexenoate (E2-6:Z3Hx), which are synergistic components of the pheromone, and the rest had E2-6:E2Hx and/or E2-6:Z3Hx without having 14:iBu. The amount of 14:iBu or octadecyl isobutyrate (the fourth pheromone component) showed a positive and significant co-relationship with the number of attracted adults. Males with a well-developed fat-body tended to have more 14:iBu and to attract more adults than those with an undeveloped fat-body. Most of the females tested individually did not attract conspecific adults, and had only (E)-2-hexenyl hexanoate, the fifth component of the pheromone.

“…For example, males of the generalist predator, the spined soldier bug (Podisus maculiventris (Say)), produce a long-range attractant pheromone that attracts both adult sexes and immatures (Aldrich et al, 1984;Sant'Ana et al, 1997). Both sexes of adult seven-spot ladybeetle C. septempunctata are attracted to 2-isopropyl-3-methoxypyrazine, a compound produced by conspecifics (Al Abassi et al, 1998).…”
