Behavioral Traits of Aphis Gossypii Glover Alatae (Homoptera: Aphididae), in Relation to Its Flight and Reproduction

Abstract

Duration of flight period (from first flight to settling) of Aphis gossypii alatae in this laboratory test varied from one to four days regardless of the colony developmental stages. Alatae in the cage with host plant flew from one to several times in daytime. The durations of the first flight of each day were the longest. The flight period did not appear to depend on the fore-wing length, teneral period or first flight duration. The total number of nymphs deposited by alatae decreased with duration of alate flight. Alatae deposited nymphs after flight, and it was found that alatae flew again when the number of embryos with pigmented eyes per ovarioles decreased. © 1990, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
