Series of experiments were conducted in the laboratory of biological control in Al-Musaib Technical college in 2015-2016 to study the effect of some plant extracted on biological performance of first and third in stare larvae of large wax worm insect.

Mortality or third instare larvae was 23.3% at concentration 2m / L of the extract Oxymatrine(SL 2.4) after three days have excelled on all treatments while it was 20% at the same concentration after one day, the results showed the other treatment of Fytoshine extract and extract hot and cold water of plant wormwood was different degrees less than oxymatrine extract, reaching 23.3%, 26.6, when feeding the third instare larva on extract cold water of wormwood after one and three days respectively while the results showed mortality the first instare when treat of extracts fytoshine, oxymatrine and wormwood plant of different ratios reaching 20.0, 23.3%, when use concentration 2mL/L of oxymatrine extract after 1 and 3 days from feeding respectively and reaching 10.0,16.6% when fytoshine exteat at concentration 2mL/L after one and three days from feeding respectively while was the extract of wormwood effect in first instare larva the mortality of extract cold water at concentration 100gm/L reaching 13.3,13.3% after one and three from feeding respectively while reaching 6.6,10.0% after one and three days respectively for extract hot water at 100gm/L concentration.
