Abstract

A laboratory study was concluded In agric..112.es. Station, Etay Elbaroud, Elbehara Gavomorate A.R.C. during 2004 season, to examine the extent of mortality In [filial (Burgess) ( Diptera - Agromyzidae ) larvae exposed to some new groups of bio insecticides using common bean as host plants . The treatments were garlic volatile oil ( Allium satiywn linn) and volatile oil of anise(fqmpinella anisum)(.06,.12,.25,.5,.75, and 1.01) compared with spinthad ( Tracer 24% WG) (0.006 ,.012 , .025 , .04 , and .05) . Also , the joint action of each volatile oil (garelic or anise oil) with the bio insecticides spinosad were carried out against the larvae of leaf miner. Spinosad was more toxic to bifolil larvae (LC50=0.011% and LCs5=0.165%) followed by anise oil (LC50=0.08% and I.0O5=0.535%)and garlic oil (LC93=0.169% andLC55=3.087%) respectively. Each of garlic and anise essential oil synergized spinosad with co-toxicity factors of +24.85 and +31.59 , respectively . Results strongly indicated that using the anise and garlic oils as a botenical bio Insecticides can be effective IPM strategies for reducing of leaf miner populations
