Abstract EN
This study evaluated the toxicity of Colocasia esculenta leaves extract on 3rd, 4th instars larvae and pupae of Culex pipiens.
Bioassays showed that the 3rd instar larvae was the most susceptible to the different concentrations of extract, where the LC50 after 48 hr.
post-exposure was 79.4l, 109.65 & 141.25 for the 3rd, 4th instars larvae and pupal stage respectively.
The histo- pathological effects of C.
esculenta leaves extract on midgut regions and gastric caeca of the 3rd instar larvae were studied.
When larvae were treated with 100 ppm of C.
esculenta extract, all larvae developed dramatic pathological lesions especially Malpighian tubules were extensively affected.
The midgut cells showed morphological deviation from normal ones, through slightly apical degenerated (lysis) of epithelial cells.
The epithelial cells with extensive cellular microvilli were shrinkage, the nuclei showed pyknotic characteristic and the peritrophic mem-brane was appeared discontinuation in compared to control.
When the 3rd larval instar was exposed to extract 400 ppm, the epithelial cells, adipose fabric and muscles were extensively affected.
Also, the gastric caeca was affected obviously.
These observation and alterations in cells of Cx.
pipiens larvae are related to the dangerous effect of C.
esculent leaves extract.
