Abstract
Two
natural biopesticides, (Boxus chinensis oil and precoceneII) were tested
against 10 days-old larvae of the red palm weevil, Rhynchophorus ferrugineus.
The two biopesticidse had toxicological and pathological effects on Rh.
ferrugineus larvae. The toxicity effect of B. chinensis was more
than precoceneII against Rh. ferrugineus.  In order of toxicity the LC50 of B.
chinensis was 0.68% while the LC50 of precoceneII was 1.36%. On
the other hand the mid-gut tissues of the 10days old larvae were exhibited
different histopathological lesions due to effect of 
B. chinensis. The alterations included analyze and destroyed of epithelial cells, vaculation of cytoplasm and dissolve of nuclei of the epithelial cells.
