Amblydromalus zannoui Sourassou, Sarmento and Moraes is a phytoseiid mite of the limonicus group described from central Brazil from leaves of physic nut, Jatropha curcas L. (Malpighiales: Euphorbiaceae), a plant potentially useful as a source of biofuel. This plant is often attacked by the mites Polyphagotarsonemus latus (Banks) (Prostigmata: Tarsonemidae) and Tetranychus bastosi Tuttle, Baker and Sales (Prostigmata: Tetranychidae). The objectives of this work were to evaluate the predation rate of A. zannoui on those phytophagous mites, to assess its life cycle on these prey and on pollen of Ricinus communis L. (Euphorbiaceae), and to determine its attraction to physic nut leaves infested by P. latus or T. bastosi. Amblydromalus zannoui attacked more nymphs and adults than eggs of P. latus, and more eggs and larvae than adults of T. bastosi. The life table parameters suggest that A. zannoui performs better on P. latus (rm: 0.20, Ro: 18.77; λ: 1.23) and pollen (rm: 0.18, Ro: 23.32, λ: 1.18). The predator seems to be attracted to plants with P. latus, but attraction was not clear cut for plants with T. bastosi. The results suggested that A. zannoui is a potential control agent to be used against P. latus on physic nut plants, and that R. communis pollen can be used as supplementary food to maintain the predator population in the absence of prey.

捕食性螨Amblydromalus zannoui控制麻疯树上害虫螨的潜力

Amblydromalus zannoui Sourassou,Sarmento和Moraes是来自巴西中部的麻疯树的一种植物寄生螨,该麻疯树是从一种可能用作生物燃料来源的物理坚果Jatropha curcas L.(Malpighiales:Euphorbiaceae)的叶子中描述的。这种植物通常是由螨虫的攻击多食黄鳍鲷(银行)(前气门:跗线螨科)和叶bastosi塔特尔,贝克和销售(前气门:叶螨科)。这项工作的目的是评估A. zannoui食草螨上的捕食率,评估其在这些猎物和蓖麻花粉上的生命周期。L.(Euphorbiaceae),并确定其对被P. latusT. bastosi侵染的物理坚果叶的吸引力。Amblydromalus zannoui攻击更若虫和成虫比鸡蛋P.黄鳍鲷,多卵和幼虫比成人T. bastosi。寿命表参数表明,A。zannoui美洲黑(r m:0.20,R o:18.77;λ:1.23)和花粉(r m:0.18,R o:23.32,λ:1.18)上表现更好。捕食者似乎被带有P. latus的植物所吸引,但是对于具有T. bastosi的植物的吸引尚不清楚。结果表明,A。zannoui是一种潜在的控制剂,可用于对抗物理坚果植物上的P. latus,并且R. communis花粉可以用作补充食物,以在没有猎物的情况下维持捕食者种群。
