“…A typical example of seasonal migration is of monarch butterfly (Danaus plexippus) moving southward in most of the United States and Southern Canada [21]. Most of the southward migrating monarch butterflies in USA are in the state of reproductive diapauses, characterized by increased lipid content, undeveloped ovaries, reduced response to reproductive and vegetative stimuli and increased sensitivity to isomers of juvenile hormone [22].…”

Diapause is defined as a period of suspended development in insects and other invertebrates during unfavorable environmental conditions. Diapause is commonly confused with term "quiescence" as both are dormant development stages. Here this paper aimed to review the research work done on different aspects of diapause. Attempt was made to explain definitions of diapause, incidence, stages and termination of diapause, genetic control, factors affecting diapauses, including temperature, photoperiod, moisture and food, etc..

“…This behavioural response to seasonal adversity is characterised by the adoption of a non-breeding status that prevails until the vernal migration (Williams et al 1942;Beall 1948;Johnsonl963;Herman 1973;Pan and Wyatt 1976;Brower et al 1977;Tuskes and Brower 1978).…”

“…A similar circumstance may exist for the females overwintering in Mexico since Van Hook (1999) reported finding many "old" spermatophores in overwintering females. This added survival advantage may also play a significant role for females overwintering in Mexico because they undergo a longer period of reproductive diapause (Herman et al 1989).…”

“…In the fall, before the milkweeds die back to their rhizomes for the winter, monarch butterflies east of the Rocky Mountains begin their long distance migration to winter sites located in the high mountains of Mexico while monarchs west of this divide, migrate to selected forested areas along the California coastline (Leong et al 2004). During the winter, monarchs are found in groves that offer protection against environmental extremes (Leong 1990) and are physiologically different from the summer generation in that they are long lived (5-6 months versus 4-6 weeks) and in reproductive diapause (Herman 1985;Herman et. al 1989;Herman & Tatar 2001).…”
