“…The response of insects under a crowding condition is usually the dispersal from the crowding location because of the increased competition for resources and living spaces. In many cases migration is the less costly solution apart from other benefits that may incur to the insect [78]. Beetles of R. dominica under crowded conditions have a significantly higher flight initiation than beetles reared on isolated kernels [30].…”

Insect movement inside and outside grain bulks and processed products influences pest management decisions. Movement allows insects to find essential food resources, shelters (refuges), warmer and/or humid locations, mating and egg-laying sites, even when they are rare in fields, buildings, mills, warehouses, and inside grain masses. This review discussed the advantages and disadvantages of stored product insect movements, and the influence of insect mobility on some integrated pest management practices. Insect movement (1) results in clumped insect spatial distributions and thus makes large sample sizes necessary for monitoring; (2) makes trapping more efficient, but is influenced by many factors; (3) allows control methods to be effective, but requires pest management programs to be area-wide; (4) makes eradication of quarantine pests difficult and commodities are quickly re-infested; and (5) results in a diverse genetic pool and speeds the development of resistance to pesticides. Any element of an IPM approach should use the knowledge of insect movement. Reasons for the difficult interpretation of cryptic movement behaviours of insects were provided and future research areas were suggested.

“…Many insects are currently known to perform long-distance movements, some of which are assigned as round-trip migration between specific locations or environments (Williams 1957(Williams , 1958Schneider 1962;Southwood 1962;Johnson 1969;Drake & Farrow 1988;Russell et al 1998;Petrakis & Legakis 2005;Dingle 2014;Chapman et al 2015). The most famous example is the monarch butterfly Danaus plexippus (Linnaeus) (Lepidoptera; Nymphalidae; Danainae) that travels thousands of kilometers from northeastern America to overwintering sites in California or Mexico in autumn and performs return migration in the next spring (Urquhart 1960;Urquhart & Urquhart 1977, 1979Calvert & Brower 1986;Brower & Malcolm 1991;Brower 1996).…”

Altitudinal migration of insects

A number of insects have been suggested to perform seasonal migration between low-and high-altitude areas. In these insects, support for the occurrence of migration mainly came from observations that focal insects disappeared from a certain range of altitudes but appeared at different altitudes with short time lags. In some insects, further support was obtained by mark-recapture studies, analyses of the seasonal change of age structure or reproductive conditions in individuals from different altitudes and studies on dormancy or temperature tolerance. Other means that can be used to assess the occurrence of altitudinal migration are briefly mentioned. Two types of migration, the dormancy-associated and dormancy-independent types, are discriminated. In the former type, insects usually breed in spring, migrate to high-altitude areas in late spring or early summer, usually for aestivation, and return to low-altitude areas in autumn. In this type, the same individuals perform upward and downward migration. In the latter type, insects also perform upward migration in late spring or early summer and downward migration in autumn, but they breed both in low-and high-altitude areas. The adaptive and evolutionary aspects of altitudinal migration are briefly mentioned.
