The Prey Preference and Functional Response of Adult Female Amblyseius eharai to the Eggs of Bemisia tabaci

摘要: 为评价江原钝绥螨对烟粉虱卵的捕食效率, 采用Hollings功能反应研究方法, 研究江原钝绥螨雌成螨对烟粉虱卵的捕食功能反应及其对不同发育阶段的烟粉虱卵的捕食选择性。结果表明江原钝绥螨雌成螨对烟粉虱初产的卵 (黄绿色) 有较强的捕食作用, 最大日平均捕食量可达8.6粒·d-1;但当烟粉虱卵变为褐色时, 捕食量则明显下降, 最大日平均捕食量仅为2.2粒·d-1。当黄绿色卵与褐色卵并存时, 江原钝绥螨优先选择取食黄绿色卵。随着猎物密度的上升, 江原钝绥螨对烟粉虱卵的捕食量逐渐增大;随着温度 (1628℃) 上升, 江原钝绥螨对烟粉虱卵的捕食效率随之提高;32℃时江原钝绥螨对烟粉虱卵的捕食效率较20℃和16℃时高, 但低于24℃和28℃。28℃时江原钝绥螨对烟粉虱卵的瞬时发现率 (a=0.8054) 最高, 猎物处理时间 (Th=0.0227d) 最短。Abstract: In the present study, the prey preference of the predatory mite Amblyseius eharai to the new eggs (yellow) and old eggs (brown) of Bemisia tabaci was examined.Our results showed that the predation efficiency of adult female A.eharai to the new eggs of B.tabaci is higher, the mean daily consumption are 8.6 (new) and 2.2 (old) eggs/day when the new/old eggs was supplied only, and the A.eharai preyed the new ones when the new/ old eggs was supplied simultaneously.Furthermore, the consumption by the adult female A.eharai increased along with the increasing of the predation density, and the predation efficiency increased along with the temperatures (16℃to 28℃) .The predation efficiency of A.eharai at 32℃ was higher than that at 20℃or 16℃, and was lower than that at 24℃ or 28℃.In addition, the highest rate of discovery of prey (a = 0.8054) and the shortest handling time (Th =0.0227) were obtained at 28℃.
