Abstract

Population dynamics of chrysanthemum fly, Trupanea
stellata
(F.) (Diptera: Tephritidae) on chamomile (Matricaria
chamomilla
) recutita was carried out in Ibshwai district, Fayoum
Governorate, Egypt during 2009/2010 and 2010/2011 seasons.
This work showed that both larval and total population had three
peaks in the first season, in the second week of Dec., at the end of
Jan. and in the second week of Feb. The highest peaks were found
by the second week of Feb. Population of the adult stage showed
five peaks. The highest was found by the second week of Jan. In
the second season the population density was much lower than that
in the first season. Larvae and total population had two peaks.
Adult flies only had four peaks. The highest peak was in the
beginning of April.
