摘要: 南方小花蝽(Orius strigicollis)是一类应用前景广阔的捕食性天敌。以芸豆豆荚作为南方小花蝽的产卵基质,研究了南方小花蝽在该产卵基质上产卵部位选择的偏好性,并以此为基础探讨了一种该产卵基质的高效利用方法。结果表明,90%以上的南方小花蝽卵被产在豆荚的荚缝线处,而且50%以上的卵被产在豆尖的荚缝处。斜45°切取豆荚的豆尖部分,并对切口处进行上蜡包裹,放置5 d切口处密封性仍保持完好,荚果保持新鲜,并且不影响卵的孵化。研究明确了该产卵基质高效利用方法的可行性,能为后期南方小花蝽室内扩繁和产品创制提供科学依据。

Abstract: Orius strigicollis is a current predatory natural enemy with strong predation ability. In the present study, kidney bean (Phaseolus vulgaris) pods were used as the oviposition substrate for O. strigicollis, and the preference of the oviposition area on kidney bean pods was studied. Additionally, an efficient utilization method of the oviposition substrate was further analyzed. Results showed that more than 90% eggs of O. strigicollis were laid in the pod seams, and more than 50% eggs were laid in the pod seams of the bean tip. Cutting the tip of kidney bean at an angle of 45°and waxing the cut was a feasible method. The method could maintain good sealing of the incision within 5 d, and kept the bean tip fresh, and did not affect the egg hatching, which indicated that this utilization method of oviposition substrate was feasible. The results provided scientific basis for the propagation and product creation of O. strigicollis in future.
