Plodia interpunctella Indian moth is a very common warehouse pest in the world, which mainly feeds on stored food products, and in fact, it has been called the most important pest of stored products. Considering that the food stocks targeted by this pest are mainly grains, legumes, nuts, dried fruits, etc., so it causes great damage to the economy of countries and families. This study intends to investigate the effect of multi-component biological pesticide in the management and control of this pest. In this study, 480 third instar larvae of Indian moth were studied. After making a multi-component biological pesticide including B. bassiana and M. anisopliae, caco3, thymol nanoparticles were tested by spraying on third instar larvae. The trend of increasing and decreasing mortality in the presence and absence of biological pesticide within 10 days of LT50 case was investigated and the biological composition was determined for each of the components. The studies showed that the use of biological composition had the lowest effective time LT50 = 4.28 and the highest mortality rate of 100% within 10 days compared to the control group. The results showed that each of the substances tested alone can cause deaths and casualties in this pest. It was also found that the simultaneous use of these compounds in the form of a bio-pesticide causes a significant increase in casualties and the percentage of deaths and accelerates the effectiveness of the bio-pesticide.
