间作与单作这两种方式,哪一种会对害虫的种群规模产生影响,是与作物多样性有关的重要问题。有人提出,杂食昆虫面对多种不同的寄主植物,较难确定其取食和产卵的寄主种类。在实验室条件下(以有选择和没有选择作比较)研究了杂食害虫B型烟粉虱雌虫的活力和生殖力, Intercropping and monoculture, both of which have an impact on pest population size, are important issues related to crop diversity. It was suggested that omnivores insects face a wide range of host plants, making it more difficult to determine the host species for their feeding and spawning. The vitality and fecundity of the omnivorous pest B female beetle were studied under laboratory conditions (with or without selection)
