Some Maternal Influences on Progeny Quality in the Western Tent Caterpillar, Malacosoma pluviale (Dyar)

摘要: The different types of individuals among the progeny western tent caterpillar, Malacosoma pluviale (Dyar), are concentrated in parts egg mass. most agile come from some first eggs laid, and least viable last deposited. There is evidence that this serial arrangement stems unequal partitioning maternal food reserves during production: a relationship similar to recently demonstrated spruce budworm by I. M. Campbell. In M . , however, there also differences feeding rate capacity displayed females their own larval stage affect proportions various per mass as well viability consecutive groups within Although these influences not heritable usual genetic sense, they clearly transmissible between generations. And field studies have shown more adverse consequences for local populations cumulative ultimately lethal.
