Abstract

Abstract In recent years, Helopeltis theivora Waterhouse (Hemiptera: Miridae) has emerged as an important pest of tea, Camellia sinensis L.O. (Kuntze) (Theaceae), in southern India. We are currently developing an ecologically and economically viable integrated pest management (IPM) program against H. theivora. In this study, we documented the biology, life table parameters, and functional response of Epidaus bicolor Distant and Sycanus collaris F. (Hemiptera: Reduviidae). Sycanus collaris produced greater numbers of eggs, required a longer incubation period, and had greater adult longevity than E. bicolor. The innate capacities of natural increase (rc) were 0.091 and 0.192 females/female/day, and the gross reproduction (mx) rates were 69.3 and 145.2 females/female, for E. bicolor and S. collaris, respectively. Both reduviid species exhibited Type II functional response. Mass rearing of S. collaris was more successful than E. bicolor, and no cannibalism was observed during rearing. We concluded that S. collaris is a promising natural enemy for H. theivora and could be incorporated into IPM programs in tea plantations.

两种红腹蛛（半翅目：红腹蛛科：Harpactorinae）在Tea1的生活史和功能反应

摘要近几年来，印度南部茶科山茶（山茶科）的一种重要害虫——水杨水杨（半翅目：水杨科）已成为一种重要的害虫。我们目前正在制定一项在生态和经济上可行的综合虫害管理（IPM）计划。在这项研究中，我们记录了双色斑蝶（Epidaus bicolor Distant）和羽扇杉（Sycanus collais F.）的生物学、生命表参数和功能反应。羽衣Sycanus collais比双色E.bicolor产下更多的卵，需要更长的孵化期，成年后的寿命更长。双色E.colais和锁骨S.colais的天生自然增长能力（rc）分别为0.091和0.192雌/雌/天，毛繁殖率（mx）分别为69.3和145.2雌/雌。两个冗余物种都表现出II型功能反应。羽衣甘蓝的大规模饲养比双色甘蓝更成功，并且在饲养过程中没有观察到同类相残。我们得出的结论是，羽衣甘蓝是H.theivora的一个很有前途的天敌，可以纳入茶园的IPM计划。

期刊介绍： The Journal of Agricultural and Urban Entomology (JAUE) (Journal of Agricultural Entomology, Jan 1984 - Oct 1998 volumes 1-15) is published under the auspices of the South Carolina Entomological Society (SCES). The Journal publishes contributions of original research concerning insects and other arthropods of agricultural and urban importance to include those affecting humans, livestock, poultry, and wildlife. JAUE is particularly dedicated to the publication of articles and notes pertaining to applied entomology, although it will accept suitable contributions of a fundamental nature related to agricultural and urban entomology.
