We have initiated the cloning of a novel protein receptor for the Bacillus thuringiensis biopesticides using the forest pest Malacosoma americanum, the Eastern Tent Caterpillar
(ETC), as our target insect.

Nine risk factors were identified by the study, and four were deemed significant: topical use of an insecticide, the presence of Eastern Tent caterpillars
, the presence of MRLS and increased illnesses.
Exploratory and recruitment trail marking by eastern tent caterpillars
Jesus must have known about the tent caterpillars
in our lives.
Some maternal influences on progeny quality in the western tent caterpillar
, Malacosoma pluviale (Dyar).
Both methods of analysis indicate modest genetic structure and high rates of gene flow at macrogeographic scales in eastern tent caterpillar
populations for virtually all of the loci analyzed.
You see, friendly flies are natural predators of the native forest tent caterpillar
, and the two species' populations are tied together in a classic predator-prey cycle.
Forestry researchers wondered why the forest tent caterpillar
attacked and fed on sugar maple trees and not red maples?
Researchers have recently been taking a look at wild-cherry trees and the proliferation of the Eastern Tent caterpillar
as a possible cause.
Examples of maternal effects are: the increased ability of autumnal moth (Epirrita autumnata) caterpillars to feed on foliage with induced defensive chemicals if their mothers originated from a high-density population (Haukioja and Neuvonen 1987); the variation in egg size and associated cold tolerance in spruce budworm, Choristoneura fumiferana (Harvey 1985); the variation of western tent caterpillar
(Malacosoma californicum pluviale) activity and survival with the history of the mother in such a way that food-stressed mothers produce less active caterpillars (Wellington 1965); and the variation in survival of offspring with food quality of the parental generation of fall webworm, Hyphantria cunea (Morris 1967).
It is the similar appearing apple tree tent caterpillar
that occurs in the spring and feeds on the newly developed foliage that can severely impact tree health.
One of several species of tent caterpillars
, the eastern tent caterpillar
is the species known for spinning silken "tents" in cherry trees across the eastern United States, including New York State.
The spring feeding done by the eastern tent caterpillar
(occurring as it does on newly emerged foliage compared to the end-of-season feeding by the fall webworm) is way more damaging to the tree.
