フジコナカイガラムシの土着天敵
フジコナカイガラクロバチに対する数種薬剤の影響

土着天敵を活用した防除体系を確立するため，カキ園で使用される殺虫剤13剤，殺菌剤 3剤がフジコナカイガラムシの土着寄生蜂フジコナカイガラクロバチに及ぼす影響を調べた．壁面接触法による試験では，IGR系殺虫剤およびBT剤はクロバチ成虫にほとんど影響を及ぼさなかったが，それ以外の殺虫剤は成虫の生存に悪影響を及ぼした．また，殺菌剤は殺虫剤に比べるとクロバチに及ぼす影響は小さかった．MEP水和剤やアセタミプリド水溶剤は悪影響期間が短かったことから，IGR系剤、BT剤および殺菌剤に加えて、この両薬剤も露地のカキにおける天敵活用型防除体系で利用できると考えられる．

Effects of Pesticides on Allotropa subclavata, an Indigenous Parasitoid of Planococcus kraunhiae. TESHIBA Mayumi and Takafumi TSUTSUMI (Fukuoka Agricultural Research Center, Chikushino, Fukuoka 818-8549, Japan) Bull. Fukuoka Agric. Res. Cent. 25: 59-63 (2006)
The effects of 13 insecticides and 3 fungicides used in Japanese persimmon orchards on Allotropa subclavata, an indigenous parasitoid of Planococcus kraunhiae (Kuwana), were evaluated by laboratory experiments. IGRs and BT were safe for, but the other insecticides were harmful to adults of A. subclavata in contact toxicity test. All tested fungicides were safer than any other tested insecticides. The period of residual contact toxicity of MEP and acetamiprid was shorter than any other insecticides. From these results mentioned above, it is considered that combining IGRs, BT, fungicides, MEP and acetamiprid with A. subclavata is effective for IPM programs of P. kraunhiae in Japanese persimmon orchards.
