为明确用于防治稻飞虱的“秕谷草-伪褐飞虱-中华淡翅盲蝽”载体植物系统的可行性,本文开展了靶标作物水稻、载体植物秕谷草和靶标害虫褐飞虱、替代猎物伪褐飞虱组合对中华淡翅盲蝽成虫形态、种群增长参数、产卵选择性和取食选择性的影响研究.结果表明:中华淡翅盲蝽水稻种群(取食褐飞虱卵)的雌雄成虫个体均显著大于秕谷草种群(取食伪褐飞虱卵).取食褐飞虱卵的中华淡翅盲蝽种群增长参数单雌产卵量、净增长率、内禀增长率、周限增长率明显高于取食伪褐飞虱卵的种群,但取食伪褐飞虱卵也有较高的种群增长能力,足以扩繁种群.对于靶标作物水稻和载体植物秕谷草,无论是水稻种群还是秕谷草种群均偏好在水稻上产卵.同时,2个种群的雌虫、雄虫和若虫对褐飞虱卵和伪褐飞虱卵捕食量没有显著性差异.在上述研究基础上,讨论了在田间建立“秕谷草-伪褐飞虱-中华淡翅盲蝽”载体植物系统的可行性.
In order to clarify the feasibility of plant-mediated plant system for the control of planthoppers, this paper carried out target plant rice, vector plant shrews and brown planthopper, Nilaparvata lugens, instead of prey pseudo-plant The effects of BPH combinations on adult morphogenesis, population growth parameters, oviposition preference and feeding selectivity of Lilium lucorum were studied.The results showed that the male and female adults of the rice population Is higher than that of the Hystrix population (feeding on the browninghopper eggs) .The growth parameters of the population of the Pipistreaceae fed on the eggs of N. lugens were significantly higher than that of the feeding falsity However, feeding on the brown planthopper eggs also had higher population growth ability, which was enough to propagate the population.For both the target crop plants and the herbaceous plant shrews, both the rice population and the shrub population preferred to lay eggs on rice. At the same time, the female, male and nymphs of two populations showed no significant differences in the amount of prey on the eggs of the brown planthopper and the brown planthopper.Based on the above studies, Brown planthopper - Chinese short-winged bugs feasibility "carrier system of the plant.
