Abstract |
|
|
Hexaflumuron, a
benzoylphenylurea derivative, was tested topically at
four doses (0.5, 1, 1.5 and 2 µg/insect) on adults of Callosobruchus maculatus (Coleoptera: Bruchidae) and first
evaluated on fecundity, hatchability and viability of eggs, longevity and
morphometric of oocytes.
Our data show that the compound reduced the longevity and the fecundity.
In addition, treatment affected growth and development of oocytes and
egg-viability as evidenced by measurements the number of oocytes per
ovaries and the size of basal follicle, respectively. In a second series
of experiments, this IGR don’t induced significant reduction of
the percentage-hatchability but its affect very
significantly the viability rate of eggs
laid by F1 females. Duration of the
embryonic and post – embryonic development of eggs laid by treated females
increase when the concentration varied from 0 to 2 µg/µl.
Key words:
Hexaflumuron, Callosobruchus maculatus, eggs development,
fecundity, longevity, morphometric of oocytes, viability. |
