馬氏捕植鑫及少毛捕植鑫捕食南黃薊馬之生活史和捕食量
Life History and Feeding Amount of Amblyseius asetus and A. maai (Acari: Phytoseiidae) on Thrips palmi (Thysanoptera: Thripidae)
摘要
在28℃及13L:11D光照下，幼期取食神澤氏葉剤（Tetranychus kanzawai Kishida）卵、成期取食南黃薊馬（Thrips palmi Karny）一齡幼蟲，馬氏捕植剤（Amblyseius maai Tseng）雌和雄性的發育期分別為6.5及5.9天；交尾雌成剤壽命40.2天，捕食薊馬幼蟲80.2隻，產卵22.6粒；未交尾雌剤不產卵，壽命21.9天，捕食薊馬幼蟲24.3隻；雄剤壽命17.5天，捕食薊馬幼蟲13隻。相同條件下，少毛捕植剤（A. asetus（Chant））全為雌性個體，為產雌孤雌生殖。發育期5.8天，成剤壽命24.5天，捕食薊馬幼蟲90.2隻，產卵43.5粒。少毛捕植剤具有用以防治薊馬的潛力，馬氏捕植剤常在茄園南黃薊馬族群中發現，應當扮演有抑制薊馬族群的角色。

The life history and feeding amount of Amblyseius maai Tseng and A. asetus (Chant) were studied in an incubator at 28℃ with a photoperiod of 13L:11D. Eggs of Tetranychus kanzawai Kishida and first instar larvae of Thrips palmi Karny were supplied as food to the immature and adult stages, respectively, of these two phytoseiid mites. The development stages of female and male individuals of A. maai lasted 6.5 and 5.9 days, respectively. Mated adult females lived 40.2 days, consumed 80.2 thrips larvae, and laid 22.6 eggs; virgin females lived 21.9 days with no egg laid, and consumed 24.3 thrips larvae; while adult males lived 17.5 days, and consumed 13 thrips larvae. No male individual of A. asetus was found during the testing period. A. asetus is apparently a thelyotokous species. Its development stage lasted 5.8 days; adults lived 24.5 days, laid 43.5 eggs, and consumed 90.2 thrips larvae. A. asetus has the potential to be used for the biological control of thrips pest. A. maai were frequently found among the population of T. palmi on eggplant. It possibly plays a role in the reduction of thrips populations.
