Abstract

<i>Lecanium tiliae</i> normally has one annual generation in southwestern British Columbia. There was a partial second in a year following a mild winter. The heaviest infestations were on horse chestnut, Japanese plum, hawthorn, and maple, in that order. Hawthorn was damaged. The proportion of males tended to be higher in high than in low populations, and to decrease with increasing altitude. Severe winter cold caused marked population decreases and cold weather in June noticeable decreases. Natural enemies found in 1969-72 are listed.
