Abstract

The goji berry psyllid, Bactericera gobica Logniova (Homoptera: Psyllidae), is one of the most important pests on goji berry plants (Lycium barbarum L.), whose fruits are widely used in traditional Chinese medicine and food. However, chemical control is still the predominant control strategy of this pest. Recently, two species of predatory mites, Neoseiulus setarius Ma, Meng & Fan and Neoseiulus barkeri Hughes were found to be associated with B. gobica in China. To assess their predation potential against B. gobica, the functional responses of these two phytoseiid species feeding on different densities (2, 4, 8, 12, 16, 24 and 32 individuals) of B. gobica eggs and 1st instar nymphs were compared at a temperature of 25ºC ± 1º C. Logistic regression analysis revealed that both predatory mite species exhibited type Holling-II functional responses on eggs and 1st instar nymphs of B. gobica, with the predation number increased for both predators as the density of prey increased. Overall, N. setarius consumed more prey compared to N. barkeri across all levels of prey densities. Meanwhile, the highest attack rate (α = 0.0283), the lowest handling time (T_h = 1.1324 h prey^- 1), and the highest estimated maximum predation rate (T/T_h = 21.19 prey day^- 1) were all observed for N. setarius fed with 1st instar nymphs of B. gobica. These findings suggest that it is worthy considering utilizing N. setarius and N. barkeri as candidate biocontrol agents of B. gobica, with N. setarius appearing to be a more effective predator than N. barkeri.

两种捕食螨（Acari：Phytoseiidae）对 Bactericera Gobica Logniova（同翅目：Psyllidae）卵和初生若虫的功能反应。

枸杞牛皮虫（Bactericera gobica Logniova，同翅目：牛皮虫科）是枸杞植物（Lycium barbarum L.）上最重要的害虫之一，其果实被广泛用于传统中药和食品中。然而，化学防治仍是该害虫的主要防治策略。最近，在中国发现了两种捕食螨，即 Neoseiulus setarius Ma, Meng & Fan 和 Neoseiulus barkeri Hughes，它们与枸杞蝙蝠相关。为了评估这两种植物螨对矢车菊的捕食潜力，比较了这两种植物螨在 25ºC ± 1ºC 温度条件下捕食不同密度（2、4、8、12、16、24 和 32 个个体）的矢车菊卵和第一龄若虫的功能反应。逻辑回归分析表明，两种捕食螨都对蝙蝠卵和初生若虫表现出霍林二型功能反应，随着猎物密度的增加，两种捕食螨的捕食数量都在增加。总体而言，在所有猎物密度水平上，N. setarius都比N. barkeri消耗更多的猎物。与此同时，用鹅膏蛙1龄若虫喂养的濑鱼攻击率最高（α = 0.0283），处理时间最短（Th = 1.1324 h prey-1），估计最大捕食率最高（T/Th = 21.19 prey day-1）。这些研究结果表明，值得考虑利用 N. setarius 和 N. barkeri 作为鹅膏蝶的候选生物控制剂，其中 N. setarius 似乎是比 N. barkeri 更有效的捕食者。

期刊介绍： Experimental and Applied Acarology publishes peer-reviewed original papers describing advances in basic and applied research on mites and ticks. Coverage encompasses all Acari, including those of environmental, agricultural, medical and veterinary importance, and all the ways in which they interact with other organisms (plants, arthropods and other animals). The subject matter draws upon a wide variety of disciplines, including evolutionary biology, ecology, epidemiology, physiology, biochemistry, toxicology, immunology, genetics, molecular biology and pest management sciences.
