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 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?
Local potential competitor species are important determinants of the invasibility of an environment even when widely recognized invasive species are concerned since it may compromise its establishment. Thus, the outcome of the direct competition among the invasive khapra beetle, Trogoderma granarium, and the cosmopolitan species lesser grain borer, Rhyzopertha dominica and rice weevil, Sitophil...
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 کاملStudies on the cholesterol ester hydrolase of Trogoderma (Coleoptera).
The enzyme cholesterol ester hydrolase (EC 3.1.1.13) was detected in the larvae of the khapra beetle, Trogoderma granarium (Everts). The pH and temperature optima for the enzyme were 6.6 degrees and 37 degrees C respectively. The mol.wt. of the enzyme was 76000-80000. The enzyme was equally effective in hydrolysing cholesteryl acetate, stearate and oleate. Cholesterol derivatives, namely the ch...
