Behavioral responses of Orius similis to Kidney Bean plants and their volatiles under different treatments
The behavioral response of female and male Orius similis to 6 kinds of kidney bean were studied by Y-tube olfactometer, the response of O. similis to 8 standard samples of volatiles at different concentrations were assessed too. The results showed that the kidney bean plant damaged by thrips nymph and adult had strong attraction to female and male adult of O. similis, no matter compared with the pure air, healthy and mechanical damaged bean respectively. Compared with healthy bean, the kidney bean plant induced by exogenous jasmonic acid ( JA) and methyl salicylate ( MeSA) hadn't significant effect to female adult of O. similis, while it had attractive to male adult of O. similis. Female adult of O. similis showed a significant preference for volatiles from JA and MeSA induced kidney bean compared to mechanical damaged bean, while male adult of O. similis didn't show a significant respond. Among the different concentrations of 8 standard samples, ( Z)-3-Hexenyl acetate, 1-Octen-3-ol, ( Z)-3-Hexenal at the dosages of 10-1 μL/μL and 1-Octen-3-ol, ( Z)-3-Hexenal at the dosages of 10 -3μL/μL showed the strongest attraction to O. similis respectively, and they were more attractive to female than male. The results indicated that different treated bean had various effects on female and male adult of O. similis, and the type and concentration of compounds had different effects too.
