3종의 살충제에 대한 담배가루이 Biotype B와 Q의 섭식행동 비교


Differentiation in Feeding Behaviour of Biotypes B and Q of Bemisia tabaci (Homoptera: Aleyrodidae) against Three Insecticides

  The feeding behaviors of 2 biotypes (type B and Q) of tobacco whitefly, Bemisia tabaci, were monitored using EPG technique on tomato and pepper plants treated 3 insecticides for controlling whiteflies, for examples, acetamiprid, spinosad and thiamethoxam. After treatment of three insecticides with recommended concentrations to tomato and pepper plants, EPG waveforms were recorded during 6 hours. The characteristic patterns of feeding behaviors investigated were as follows, time consumed by withdrawal of proboscis, total non-penetration time, total stylet pathway pattern time and total phloem feeding time. There was somewhat difference among 3 insecticides tested. As a result of investigation of total duration showed the stylet pathway activity due to the reaction against all tested insecticides, the Q biotype showed fewer time than those from the B biotype. The B biotype showed more frequent stylet pathway activity patterns during whole recording time and a shorter phloem ingestion time than those from the Q biotype. In result of prior np (non-penetration) time representing the reaction against the insecticide treated, the time of B biotype was more faster than that of the Q biotype, so it was considered that the B biotype was more sensitive to the tested insecticides. Therefore, our results revealed a clear difference in feeding behaviour between the Band Q biotypes of B. tabaci. Also, it was investigated that B biotype was susceptible to the 3 insecticides.
