To better identify the insect predators, fruit may be stored to allow the insects inside to reach maturity. Care must be taken to avoid damp and the chance of escape, as some beetles may be less the 1mm in size.
Once beetles emerge they should not be killed immediately as their internal organs, vital for identification, take approximately 2 – 3 days to harden. Beetles should be collected into tubes of 70% ethyl alcohol for study.
Moths should be killed immediately, and micropinned with the wings spread.
