Book excerpt: Excerpt from Connecticut State Entomologist 46th Report, 1946 In the practical use Of such materials, efficiency in application is always a significant item, and the apparatus which can be employed economically may be very important. The recent development Of airplane sprayers 'and mist blowers for dispensing concentrated liquid mixtures has markedly in creased the practicability Oi controlling certain pests. In the initial development Of new materials, the cost has a minor place. The Objective is to find the toxicity and the possibilities Of utilization and allow the price factor to be the last one involved in rejecting or accepting the chemical compound. Although our knowledge Of the action Of chemical compounds on pests has increased more in the last 10 years than during any Similar preceding period, we cannot use these compounds without a detailed knowledge of the habits, life' cycle and ecology Of the pest involved. Such factors as manner Of feeding, location, reaction to the environment, reproductive potential, length Of different stages in the life cycle, injuriousness, are vital to the success Of any Spraying or dusting Operation.
