A quadratic regression model (Y = 4.015 + 0.4419X − 0.001036X2) for forecasting defoliation potential by larch casebearer on western larch was developed. The model utilizes systematic counts of overwintering larvae of Coleophora laricella (Hubner)

An egg sampling plan, designed to forecast potential defoliation by Croesia semipurpurana (Kearfott), was developed using egg counts on two 15-in. branch samples per tree on 4 trees per plot. This system correctly forecasts defoliation into 3 categor

The parasite Telenomus alsophilae Viereck oviposits on eggs of its host, the elm spanworm, Ennomos subsignarius (Hubner), during April and May. Peak parasitism occurs about 3 weeks prior to the time host eggs hatch in the field. Development in the ho

Estimates of atomization of an aqueous spray applied by aircraft were obtained by the D-max method and Quantimet image analyzer and compared. Results indicate that the D-max method is a reliable technique for making rapid field estimates of droplet V
