| ヒメジンガサハナカメムシの発育と繁殖に対するミナミキイロアザミウマとカンザワハダニの餌の適合性を明らかにするため,それぞれの餌種を与えた場合の本種幼虫の生存率と発育期間,雌成虫の寿命と産卵数を比較した.ミナミキイロ1齢幼虫や2齢幼虫を与えた場合,本種1齢幼虫は発育できたが,ミナミキイロ雌成虫を与えた場合,ほとんど発育できなかった.一方,カンザワハダニは苦虫だけでなく雌成虫を餌として発育可能で,本種1齢幼虫の好適な餌であった.加齢にともない餌の違いが及ぼす影響は小さくなり,ヒメジンガサハナカメムシ5齢幼虫の生存率と発育期間,雌成虫の寿命と産卵数は,餌の種類の違いによる影響は受けなかった.従って,カンザワハダニもミナミキイロと同様にヒメジンガサの発育や繁殖に対して餌適合性が高いと考えられ,ヒメジンガサはこれら2種の害虫に対する天敵資材としての利用可能性があることが示唆された. Effects of the prey species Thrips palmi and Tetranychus kanzawai and their stages on the development and reproduction of the anthocorid predator, Wollastoniella rotunda, were investigated under laboratory conditions. When offered first or second instar larvae of T. palmi, first instar nymphs of W. rotunda developed into second instars; however, when offered adult T.... |

| This study aims to evaluate the control efficacy of greenhouse whitefly by co-application of entomopathogenic fungus Lecanicillium muscarium hybrid strain 2aF43 and greenhouse whitefly parasitoid Encarsia formosa, and to reveal the interaction between both natural enemies. Although, the emergence rate of adult greenhouse whitefly reached 93.2% in control plot, co-application plot indicated significantly lower emergence rate (4.2%). Co-application plot showed higher fungal infection compared with singularly L. muscarium inoculated plot. Parasitization rate in singularly E. formosa released plot reached 81.7% and emergence rate of parasitoid was 72.1%, but lower parasitization and emergence rate of parasitoid (13.2% and 2.0% respectively) were detected on... |
