| pheromonal cross-attraction in true bugs (heteroptera): attraction of piezodorus hybneri (pentatomidae) to its pheromone versus the pheromone of riptortus pedestris (alydidae). | we investigated the attractiveness of a synthetic form of the pheromone of the soybean stink bug, piezodorus hybneri (gmelin), under field conditions, and compared it with that of (e)-2-hexenyl (e)-2-hexenoate, a pheromone component of a competitor, riptortus pedestris (fabricius). many adult stink bugs were attracted to traps baited with 100 mg of the synthetic pheromone (1: 1: one mixture of ß-sesquiphellandrene, (r)-15-hexadecanolide, and methyl (z)-8-hexadecenoate), but few were attracted t ... | 2010 | 22182564 |
| interspecific pheromone cross-attraction among soybean bugs (heteroptera): does piezodorus hybneri (pentatomidae) utilize the pheromone of riptortus clavatus (alydidae) as a kairomone? | the chemical and ecological function of cross-attraction of piezodorus hybneri (pentatomidae) to the riptortus clavatus (alydidae) pheromone (a mixture of three components) was studied. in a field attraction test using traps with synthetic pheromone components, p. hybneri was attracted to (e)-2-hexenyl (e)-2-hexenoate, a component of the r. clavatus pheromone. other components had neither an additive nor a synergistic effect on the attraction of p. hybneri. neither (e)-2-hexenyl (e)-2-hexenoate ... | 2006 | 16705488 |
| attraction of piezodorus hybneri to the aggregation pheromone components of riptortus clavatus. | the aggregation pheromone of riptortus clavatus (heteroptera: alydidae) consists of (e)-2-hexenyl (z)-3-hexenoate (e2hz3h), (e)-2-hexenyl (e)-2-hexenoate (e2he2h), and myristyl isobutyrate (mi). experiments were conducted to examine the attraction of piezodorus hybneri (heteroptera: pentatomidae) to the pheromone components of r. clavatus, individually and in combination, and to determine if p. hybneri produces these compounds. electroantennogram (eag) responses of p. hybneri to e2he2h were sign ... | 2006 | 16586037 |
| insecticide susceptibility of nezara viridula (heteroptera: pentatomidae) and three other stink bug species composing a soybean pest complex in japan. | the susceptibility of the stink bug species nezara viridula (l.), nezara antennata scott, piezodorus hybneri (gmelin), and riptortus pedestris (f.) to insecticides was tested, establishing their 50% lethal dose (ld50) values as baseline data. third instars and adults of the four species were treated by topical application with seven insecticides: fenitrothion, fenthion, etofenprox, silafluofen, dinotefuran, clothianidin, and ethiprole. the weight of the stink bug and weight of the insecticide ap ... | 2012 | 22812144 |
| synthesis of both enantiomers of 15-hexadecanolide, a sex pheromone component of the stink bug, piezodorus hybneri. | both enantiomers of 15-hexadecanolide, a sex pheromone component of the stink bug (piezodorus hybneri), were synthesized by using the yamaguchi or mitsunobu macrolactonization reaction of (r)-15-hydroxyhexadecanoic acid prepared from ethyl (r)-β-hydroxybutyrate in 5 steps. | 1998 | 27388652 |
| morphological diversity of the labial sensilla of phytophagous and predatory pentatomidae (hemiptera: heteroptera), with reference to their possible functions. | sensory structure on the labial surface of five genera of pentatomidae (hemiptera: heteroptera) belonging to two subfamilies i.e. asopinae and pentatominae have been studied using scanning electron microscopy. three representatives of the subfamily pentatominae (phytophagous)-dolycoris indicus (stal), plautia crossota (dallas) and piezodorus hybneri (gmelin) and two of asopinae (predatory)-perillus bioculatus (fabricius) and eocanthecona furcellata (wolff) were studied to morphologically charact ... | 2015 | 26624484 |
