Abstract

Megalurothrips usitatus (Bagnall) (Thysanoptera: Thripidae) is an important pest of cowpeas, Vigna unguiculata (L.) Walp., and can cause severe damage to the crop. Lasioseius lindquisti (Tseng) (Acari: Blattisociidae) and Lasioseius scapulatus (Kennett) (Acari: Blattisociidae) are 2 mites used against M. usitatus in Hainnan, China. The functional responses of these mites were examined in the laboratory. Lasioseius lindquisti showed a type III functional response, with a maximum prey consumption of 22.38 ± 0.63 per day. Its optimal search density for each unit in this experiment was 10.27 ± 0.50 per day. Lasioseius scapulatus showed a type II functional and an attack rate on 1st instars of M. usitatus of 0.83 ± 0.23. The handling time (h) of L. scapulatus was 0.074 ± 0.018 (means ± SE), while the maximum attack rate (T/Th) of adult females on 1st instar thrips was 13.51. Our results showed that both L. lindquisti and L. scapulatus are potentially useful predators of M. usitatus.

豇豆（Vigna unguiculata， L.）是豇豆的重要害虫。Walp。会对作物造成严重损害。林氏蜱（Tseng）（蜱螨亚纲：白螨科）和镰形蜱（Kennett）（蜱螨亚纲：白螨亚纲）是在海南地区防治白螨的2种螨类。在实验室检测了这些螨的功能反应。林氏螯虾表现为III型功能反应，最大食用量为22.38±0.63 / d。本实验中各单元的最优搜索密度为10.27±0.50个/天。肩胛骨裂裂肌呈II型功能，攻毒率为0.83±0.23。对1龄蓟马的处理时间(h)为0.074±0.018 (mean±SE)，雌成虫对1龄蓟马的最大攻击率（T/Th）为13.51。结果表明，林氏夜蛾和肩胛骨夜蛾都是潜在的有用捕食者。
