Notes	Host searching efficiency of female adults of Aphytis yanonensis and Coccobius fulvus, introduced parasitoids of Unaspis yanonensis, was investigated in the laboratory, using mandarin orange (Citrus unshiu) leaf patches (4×4 cm) with host density of 1, 2, 4 and 8 per patch. We recorded host searching and oviposition behavior of individual female parasitoids until they left the patch. In the higher host density A. yanonensis females attacked more hosts than A. fulvus females when comparing the number of host attacked for 30 or 60 minutes after the patch entrance. This was because of the longer oviposition time per host atlack in C. fulvus than in A, yanonensis. However, patch resident time of C. fulvus was longer than that of A. yanonensis, and no significant difference was detected in the number of hosts attacked and parasitized when compared them per patch visit. It was suggested that the host searching efficiency per unit time was higher in A. yanonensis but that the host searching efficiency per patch visit was not different because C. fulvus stayed the patch longer.
Notes	ヤノネイガラムシの導入寄生蜂ヤノネキイロコバチとヤノネツヤコバチ雌成虫の規制探索効率を, 4×4cmに切ったウンシュウミカンの葉をパッチとし, パッチあたり奇主密度を1, 2, 4, 8として蜂を1頭ずつ放し調査した. 蜂がパッチに侵入して離脱するまでを実験時間とし, 被寄生奇主数だけでなく, パッチ侵入から離脱までの蜂の奇主探索行動や産卵行動を調査した. 奇主密度が高くなると, パッチ侵入後30分までと60分までの攻撃奇主数は, ヤノネキイロコバチの方が多かった. これは, ヤノネキイロコバチの攻撃当たり産卵時間がヤノネツヤコバチより短いからであった. しかし, パッチ滞在時間はヤノネツヤコバチの方が高かったので, パッチ訪問あたりの被寄生奇主数と攻撃奇主数を比較したところ, 2種間で有意差がなかった. 以上の結果から, 単位時間当たり奇主探索効率はヤノネキイロコバチの方が高いが, ヤノネツヤコバチはパッチ滞在時間が長いので, パッチ訪問当たり奇主探索効率は2種間で差がないことが明らかになった.
