Connecticut State Entomologistforty-second report 1942 R. B. Friend During the present war emergency, and perhaps for some time there-after, Connecticut farmers will be expected to produce maximumcrops of fruits and vegetables. In the production of these crops, adequateinsect pest control is an important factor, for without it the harvest maybe a failure. There is no virtue in raising crops to support insects or anyother pests. The insect control problem, pressing enough in normal times,is made more acute by the current shortages of labor, supplies and equip-ment. Production must be efficient, and a comprehension of the factorsinvolved will aid in attaining this efficiency. Insect pest control is fundamentally the suppression of insect popu-lations to an innocuous level. This is a poorly defined limit, but we canassume that if the insect is detrimental to human welfare, then the effortto suppress it should be extended
