The bundles made of the twigs and leaves ofPopulus nigra“Italica”L. have been used to catchH. armigeraadults since 1956. One hypothesis for explaining the mechanism is physical performance, such as providing a shelter or a mating site; another is olfactory performance, such as feeding attraction as well as the stimulations of sex pheromone production, egg-deposition, or calling. We found both aromatic compounds and GLVs elicited strong EAG responses, and field experiments revealed that the active compounds are mainly floral ordours as shortside-chain aromatic alcohols and aldehydes, suggesting the mechanism was mainly feeding attraction. Additionally, agaropectin was used as the matrix of insect attractants for the first time.
Trails of sexPheromonesof rice stem borers in Lujiang, Anhui Province demonstrated that there were seasonal shifts for trappingChilo suppressalismales. A lure (162.3 µg Z-11-16: Ald, 81.3 µg Z-9-16: Ald 56.4 µg 16: Ald, and 30.3µg Z-13-18: Ald) produced five-fold trap catches of the first generation as did the natural blend. Trap catch may depend on the ratio of Z11- and Z9-16: Ald. Toelucidatethe result, another trail aimed to compare the effects of Z11-/Z9-16︰Ald on the trap catch systematically was conducted in Xinyang, Henan Province, however, the optimum ratios were 9:1 and 8:2 being close to the natural ratio (10:1), indicating geographic variation maypresentinC. suppressalissex pheromone.
On-going Projects: Screening of behavioral regulators of storage pests
Future interests: Bio-control of insect pests in orchard
