Abstract

The toxicity of two plant extracts Allium sativum L. and
Euphorbia helioscopia L. in addition to virulence of Pencillium
funiculosum
and their latent effect were investigated on the tomato
leaf miner,
Liriomyza sativae and two of associated parasitoids,
ectoparasitoid,
Neochrysocharis formosa (Westood) and
endoparasitoid,
Neochrysocharis punctiventris (Crawford).
Regarding toxic effect,
A. sativum extract was the most toxic at
LC
50 values against L. sativae while penicillium spores suspension
was the least active and
E. helioscopia extract lies in between. Also,
the adult stage was more sensitive for all used plant materials than
pupae followed by larvae. Concerning latent effect,
E. helioscopia
extract was more effective on the different stages of L. sativae
whereas P. funiculosum was more effective on the ecto and endo
parasitoids.
