Efficacy of cinnamomum zeylanicum on third stage larvae and adult fecundity of musca domestica and anopheles pharoensis

Abstract EN

The insecticidal activity of Cinnamomum zeylanicum against the larval maturation and adult emergency of Anopheles pharoensis and Musca domestica 3rd stage was evaluated under controlled laboratory conditions.

A.

pharoensis with concentrations (conc.) of 100 %, 70 %, 50 %, 25 %, 5 %, 2 %, 1 %, 0.9 %, 0.7 % and 0.5 % showed 100 % larval mortality.

Conc.

of 0.3 %, 0.2 % and 0.1 % caused mortality of 77.8 %, 44.4 % and 33.3 % respectively.

The fecundity of emerged adults was 0 %, 60 % and 50 %.

In M.

domestica the conc.

from 50 %-100 % completely killed the larvae.

Conc.

of 25 %, 5 %, 2 % & 1 % caused mortality of 88.9%, 55.6 %, 33.3 % and 22.2 % respectively.

Less conc.

of C.

zeylanicum was not tested.

The fecundity of the emerged adults was 0 %, 66.7 %, 66.7 % and 83.3 %.

Only one control larva died and the nine emerged adults were fertile in the two cases.
