The developmental biology of Aleurodicus dispersus
Russel., have been investigated. It was found to have a
cumulative developmental period of (23 - 41) days. The mean
numbers of egg developing to adult have been found to be
138.1 per thousand eggs. The spread of the insect have been
found to be connected to human traffics. The oviposition and
feeding occurs simultaneously and occur more on their
abaxial surface of host leaves. Rainfall and temperature
play a prominent role on the abundance and seasonal
fluctuation of the insect and infact, regulating their
population. Presently, A. dispersus is found on
arable as well as ornamental plants but rarely on gramminae.
At present, A. dispersus is a minor pest with the
potential of becoming a serious pest with the increasing
global warming.
Key words: Aleurodicus dispersus, oviposition,
abaxial surface, abundance, gramminae. |
