Abstract

ABSTRACT: The red cotton bug, Dysdercus koenigii F. (Hemiptera: Pyrrhocoridae) is a destructive pest of cotton in the cotton belt region of Pakistan. This pest attacks the cotton bolls, mature cotton seeds and causes serious damage to premature bolls. A trial was conducted under laboratory conditions to check the predatory potential of A. coquebertii on different stages of D. koenigii. Four stages of D. koenigii i.e. 3rd, 4th, 5th nymphal instars and adults were provided to A. coquebertii adults to check their survival, fecundity response and feeding potential. Results were statistically significant when comparing feeding preferences of A. coquebertii on different stages of D. koenigii. Adult male and female longevity of A. coquebertii was significantly higher when these insects were fed with 3rd instar nymphs of D. koenigii, which was 115.25 ± 6.91 and 88.75 ± 4.64 days, respectively. Maximum egg laying percentage of 34% was recorded on medium 3 and minimum egg laying percentage of 16% was recorded on medium 2. Based on the results of this study, survival and fecundity rate of A. coquebertii can be highly affected when the suitable stage of D. koenigii is not present.

柯氏锥蛛（半翅目：锥蛛科）在柯氏锥虫不同阶段的生存和产仔

摘要/ ABSTRACT摘要:巴基斯坦棉区红棉螟(Dysdercus koenigii F.)是一种危害棉花的害虫。这种害虫侵害棉铃和成熟棉籽，对早铃造成严重损害。在实验室条件下，研究了coquebertii对不同阶段柯尼氏夜蛾的捕食潜力。用3、4、5期科尼氏夜蛾若虫和成虫分别饲喂科尼氏夜蛾成虫，测定其成虫的成虫存活率、繁殖力和取食潜力。对不同阶段柯尼氏夜蛾的取食偏好进行比较，结果具有统计学意义。与科尼氏夜蛾3龄若虫同食可显著提高coquebertii成虫的雄、雌寿命，分别为115.25±6.91天和88.75±4.64 d。培养基3的产蛋率最高为34%，培养基2的产蛋率最低为16%。根据本研究结果，当科尼氏夜蛾的适宜期不存在时，coquebertii的存活率和繁殖率会受到严重影响。
