Abstract: Pigeon pea (Cajanaus cajan) is an one of the most important crop in majority of countries and it is too hard to protect it from the stored grain insect damage which resulted loss in grain weight, decrease in germination potential and reduces nutritional value, quality as well as market prices of the commodity. The use of synthetic fumigants and insecticides. Most of these chemicals lose their efficacy when Callosobruchus chinensis develops resistances to them. So, the use of plant product as storage grain insect control technique i.e. different plant product powders in combination of diatomaceous earth is being used to control the Callosobruchus chinensis. The present investigation entitled “Assessment of non-chemical techniques against stored grain pests with special reference to pigeon pea infesting pulse beetle” was conducted at AICRP on PHET, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS) during 2019-2021. Experiments were carried out Completely Randomized Design with thirteen treatments and three replications. One kg of pigeon pea grain was taken for each replication of treatment. The thirteen treatments were included with untreated control. The results indicated that the treatment T₁₁ (CASP@ 15g/kg+ CSP @15g/kg+ NSP@ 15g/kg+ DE @15g/kg) was found significantly superior over rest of the treatments and recorded significantly lowest number of egg laid grain at 30 (6.33) and 60 (9.67) DAS during 2019-20, 2020-21 and 2021-22. Followed by treatment T2 (CASP@ 15g/kg) 6.67 and 13.89 respectively. The minimum per cent damaged grains and per cent grain weight loss recording in treatment T₁₁ from 30 to 180 DAS followed by Treatment 2 (CASP@ 15g/kg) during three years study.
