Influence of Various Natural Indigenous Plant Products against Trogoderma granarium Everts on Wheat

Natural indigenous plant products viz., Melia azadarch, Linum usitatissimum, Cyperus rotundus, Ocimum americanum, Sussia occidentalis, Datura stramonium, Azadirachta indica and Carthamus tincotorius were tested against Trogoderma granarium to see its growth and development behaviour i.e., fecundity (22.67 to 5.13 eggs), incubation period (9.33 to 6.67) day, larval period (18.67 to 25.33 days), pupation (%) (19.33 to 36.67%), pupal duration (12.00 to 13.30 days), grain damage (4.67 to 30.67%) and eventually grain weight loss (1.86% to 23.33%). All the grain protectants protected the grain from T. granarium significantly in comparison to untreated check.
