Abstract

 

 


This study deals with using of anis seeds extracts to synergy the synthetic pyrethroid
insecticide Sumicidin against confused flour beetles Tribolium confusum .Also found percents
of mortality to different concentrations of insecticides alone and mixture with extract by
different mixture ratios. Lethal concentration of 50(Lc50) value was concluded then
synergistic ratio for sumicidin alone tests and the using ratio tests mixture too. Results show
that mortality ratio of insects exposed to sumicidin alone were increased more than to mixture
,so the mortality ratio of the concentration (0.1)ml/l as (24.09) in the mixture ratio (1:1) and
(44.4)in (1:3)for the same concentration while there was no mortality ratio in sumicidin alone
test .Experimented insects were recorded the highest responsible degree to sumicidin alone in
(0.5)ml/l concentration while ahigh degree for the mixture of sumicidin and extracte was in
(1:3) as (44.4) in (0.1)ml/l concentration .Also study was showed the Lc50value for sumicidin
alone (5.4)and for mixtures ratios (2.5) (0.5) respectively .Study showed that the anis extract
was synergetic sumicidin as(2.3)fold in the first mixture ratio and (1.8)fold in the second
mixture ratio.
