INFLUENCE OF TRICALCIUM PHOSPHATE ON POPULATION DEVELOPMENT IN THE KHAPRA BEETLE, TROGODERMA GRANARlUM EVERTS'"
The effect of n 2.5% concentration by weight of lricalcium phosphate in a wheat genn diet on the demographic parameters (life table) of the khapra beetle, Trogoderma grallarium Everts, was investigated. This sublethal concent.ration of tricalcium phosphate, a known insect population suppressant for many slored-product insect and mite species. caused no significant changes in either the intrinsi...
متن کاملAnti-feedant and growth inhibitory effects of seed extracts of custard apple, Annona squamosa against Khapra beetle, Trogoderma granarium
The anti-feedant and growth inhibitory effects of seed extracts of custard apple in hexane, ethyl acetate and methanol were tested against neonate and 7 days old larvae of the Khapra beetle, Trogoderma granarium, using a feeding bioassay. The LC50 values for hexane, ethyl acetate and methanol extracts were 1195.41, 305.36 and 1446.32 ppm for neonate larvae; 5805, 1300 and 5815 ppm for 7 days ol...
متن کاملInvader Competition with Local Competitors: Displacement or Coexistence among the Invasive Khapra Beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), and Two Other Major Stored-Grain Beetles?
