Real Estate Show Place Wednesday 978 Tent caterpillar troublesome By Wayne Roberts SsOs and Crops Branch Ontario Ministry of Agriculture and Pood One of the most frequent spring feeding Insects troublesome to the home gardener la the Eastern tent caterpillar presence or tbia insect pest Is obvious from defoliation and the formation of large unsightly silk tents Favorite host plants are wild cherry and apple although tent caterpillars attack a wide variety of deciduous trees and shrubs Including flowering cherry crabapple plum peach oak birch hawthorn privet and linden When excessively abundant trees may be completely defoliated Tent caterpillar spend winter In the egg stage Eggs are laid In large masses containing 300400 eggs per cluster The cluster usually forms a band en circling a small twig or branch The entire egg mass Is covered by a brownish gluey substance which the cluster and holds the twig Egg clusters are often mistaken for cocoons or galls on he twigs When the first buds open In the spring eggs hatch and the young larvaebegln to feed on expanding buds As larvae develop they feed voraciously on the foliage The larvae are social and those hatching from a single egg cluster remain together to construct a silk tent or web The teat to small Initially but enlarges gradually aometimes to nearly two feet in length Tents are commonly found In the crotch systems of the main branches of a tree or shrub The larvae forage for food during the warmer part of the day and In the evening when it is not too cold Tbey return to their tents when storms rain or heat provide un favorable conditions for feeding Full grown larvae are about two Inches long black with a light stripe down the back and dots of blue end white along the sides They are covered with fine soft yellowish hairs The larvae mature in June and wander off Individually from the tent to a protected site where they pupate in a loosely woven cocoon The cocoon Is oval white In color dusted with a yellowish powder and held in place by a few irregular coarse threads The pupal period lasta about three weeks then the adults emerge The adult moth emerges between the last week of June and first week In July the eggs are laid soon after The moths are dull reddishbrown marked on the front wing by nearly oblique whitish fines and have a wing span of approximately two inches Only one generation la produced each April Egg masses are readily visible on small trees and shrubs during winter and can be removed by hand picking or pruning and destroyed The collection of winter egg masses Is one of the easiest control methods for the borne grower When young larvae start to form a tent It may be pulled or cut from the branch and destroyed Sometimes if the tent is located In the main crotch of the trree or on a large branch It Is not possible to remove the tent without harming the tree Tearing the tent open In the early spring while it is still small exposes the larvae to the clangers of cold nights or rains Prevention Usually it is not necessary to spray large shade trees In the home garden targe trees can tolerate considerable Insect feeding without severe damage to the trees vigor If defoliation occurs In sue years the tree may be weakened and control measures may be necessary to ensure survival When spraying large trees the work should be done by a licensed pest control operator or by a tree maintenance service Young shade trees to seven meters high may be effectively sprayed using a hoseend sprayer When using any chemical Insecticide avoid inhalation of spray drift or contact with the skin or eyes If tent caterpillar numbers warrant spraying apply one of the commonly available Insecticides when rvae start feeding In May Some chemicals registered for garden use include car- dlazinon and Once a tree has been defoliated by extensive feeding injury the tree may refoliate New leaves can be produced from buds destined to produce foliage the following year or existing shoots may continue to produce foliage since Bedrooms family room fireplace Hollywood kitchen K acre lotat Hornby Acres and 3 Bedroom raflnfahed home 5 acre separation Asking 3 Bedroom
