Webbof the insects can be differentially affected by the cli-mate change, i.e. the growth can be accelerated by higher temperature, but at the same time the length of diapause may be extended. Those insects developing without winter diapause, which are active during this season and are protect-ed from the low temperature, are the best candidates WebbKai, H., & Nishi, K. (1976).

WebbRhea: Diapause in insects is largely controlled by the endocrine system. All the typical hormones we know of and love; PTTH, JH, ecdysteroids. Like in Manduca, when they are going into their pupal state to overwinter, it is due to a lack of ecdysteroids, which is in turn due to the prothoracic gland not producing enough ecdysteroids. WebbDescription. Chrysolina quadrigemina is a member of the Chrysomelidae, the same insect family that contains the Colorado potato beetle. Its shape and habits are similar to those of this common and destructive pest of solanaceaous plants. When disturbed, Chrysolina spp. beetles will drop from the plant and "play dead" on the soil.
