We quantified the life table parameters and predation capacity of a generalist predatory mite, Wainstein and Arutunjan on five monotypic diets, including Koch (TSSM) eggs in the presence (S) and absence (S) of webs, Westwood (GHWF) eggs (G), honeydew (H), and maize pollen (M) as well as three mixed diets, including S + M, S + G, and G + M. Our results showed that the individuals fed on the mixed diets had a considerably shorter developmental time and pre-oviposition period (APOP), higher oviposition days, higher fecundity and population growth rate than those raised on the monotypic diets. Furthermore, we found that the mixed diet of TSSM and GHWF eggs was the most favorable diet, resulted in the highest fecundity and population growth rate, shortest developmental time and APOP. While TSSM eggs alone in the presence of webs and honeydew were the worst diets resulted in the longest developmental time, lower oviposition day, higher fecundity and population growth rate. Our data determined that TSSM has more nutritional benefits than GHWF for . We observed the positive effects of pollen addition to prey on the predatory mite's immature and adult life-history characters; however, it reduced the predation rate. Overall, maize pollen could enhance ecosystem services provided against spider mites and whiteflies by positively impacting the increase of population. This predator may be more effective when two prey species are available than when only one species is present.
我们对一种多食性捕食螨——韦恩斯坦捕食螨和阿鲁图尼扬捕食螨在五种单一食物上的生命表参数和捕食能力进行了量化，这五种单一食物包括有网（S）和无网（S）环境下的科赫（番茄潜叶蛾）卵、韦斯特伍德（温室粉虱）卵（G）、蜜露（H）和玉米花粉（M），以及三种混合食物，包括S + M、S + G和G + M。我们的结果表明，与以单一食物饲养的个体相比，以混合食物饲养的个体发育时间和产卵前期（APOP）明显更短，产卵天数更多，繁殖力和种群增长率更高。此外，我们发现番茄潜叶蛾卵和温室粉虱卵的混合食物是最有利的食物，能带来最高的繁殖力和种群增长率，发育时间和APOP最短。而单独的番茄潜叶蛾卵在有网和蜜露存在的情况下是最差的食物，导致发育时间最长，产卵天数减少，繁殖力和种群增长率较低。我们的数据表明，对于……而言，番茄潜叶蛾卵比温室粉虱卵具有更多的营养益处。我们观察到在猎物中添加花粉对捕食螨的未成熟和成年生活史特征有积极影响；然而，这降低了捕食率。总体而言，玉米花粉可以通过对……种群增加产生积极影响来增强针对叶螨和粉虱的生态系统服务。当有两种猎物可供选择时，这种捕食者可能比只有一种猎物时更有效。
