2.Synthetically, N2 and N1 had greater contribution on the arthropod community and its phytophagous and predacious sub-communities in grapery, comparing with other characteristic parameters.
植类亚群落N、N2、N1和物种数S标准回归系数绝对值较大,对植类亚群落贡献大;
3.The reproduction fitness of methidathion resistance predacious mites Amblyseius womersleyi Schicha (Acari: Phytoseiidae) were studied at 20℃, 25℃ and 30℃, respectively.
