Migration in Insects: Cost and Strategies

The Journal of Animal Ecology, 1993
1. An optimal energy partitioning model is used to predict the optimum adult sizes of the soma, gonads and flight apparatus in insects. A comparison of the investment in gonads and lipoidal reserves in winged and unwinged individuals in species from three families of aphids is used to test the predictions and define the cost of developing a flight ...

Migration strategies of insects.

Science (New York, N.Y.), 2010
Physiological and ecological results from a variety of species are consistent with what seem to be valid general statements concerning insect migration. These are as follows: (i)During migration locomotory functions are enhanced and vegetative functions such as feeding and reproduction are suppressed.

Long-Distance Migration of Rice Insects

1991
The Asian rice plant is considered to have originated in the Assam-Yunnan area and to have a spread during the last few thousand years over a wide area extending from 51° N to 35° S latitude at various elevations from sea level up to 2,000 m. It harbors many insect pests which have been disseminated with the rice plant itself or are endemic to the ...

INSECT MIGRATION (IN ORTHOGRAPHS)

Ethological features of locusts in the process of migration were studied and their nature was revealed. In particular, Dociostaurus kraussii Ing. and Calliptamus turanicus Tarb. belong to the group of individually migratory locusts. The locusts types of Calliptamus italicus italicus L. and Dociostaurus maroccanus Thunb. migrate in large numbers.
