I'm planning to research on Pochazia shantungensis(Hemiptera: Ricaniidae),one of the polyphagous insects.
So, I collected the eggs, and have been rearing the nymphs with sunflower and bean. I thought they get the enough nutrients, but that they don't seem to grow at their usual rate.
I wonder, do polyphagous insects prefer specific plants and survive only a single host? or do they prefer to feed on various types of host for some reason like nutrients?
I want to investigate what host they really prefer for efficent pest control, but in recent study, it is said that there are more than 30 host they specially prefer.
