Stored product pests can cause significant damages and great economic problems in stored commodities grain cereal. Using synthetic pesticides the storage pest control has adverse effects on human health. In our study, toxicity of garlic (Allium sativum) parsley (Petroselinum crispum) essential oils (EOs) impregnating with three types bags were assessed against Trogoderma granarium Everts, 1898 ...

medicinal plant powders have traditionally been used as grain protectants against stored-product insect pests. in this study, insecticidal activity of carum copticum l. and cuminum cyminum l. powders was assessed on adults of sitophilus granarius l. and tribolium confusum jacquelin du val. experiments were carried out on wheat at 27 ± 1 ºcand 55 ± 5% r. h. the mortality increased with increasin...

rearing methods for bracon hebetor (say) (hym., braconidae) were investigated in the series of laboratory experiments designed to enhance the yield of the mass rearing of this parasitoid for biological control of lepidopteran field and stored product pests. in these experiments, the effects of parasitoid and host densities on fertility and sex ratio of b. hebetor were assessed. in parasitoid de...

abstract due to economical importance of stored product pests and resistance to conventional insecticides, it is necessary to use novel and suitable compounds in control programs. therefore, we evaluated the toxicity of spinosad to three important storage insect, red flour beetle, tribolium castaneum (herbst), rice weevil, sitophilus oryzae (l.), sawtoothed grain beetle oryzaephilus surinamensi...

In order to find and develop new botanical pesticides against tobacco storage pests, bioactivity screening was performed. The essential oil obtained from the aerial parts of Liriope muscari was investigated by GC/MS and GC/FID. A total of 14 components representing 96.12% of the oil were identified and the main compounds in the oil were found to be methyl eugenol (42.15%) and safrole (17.15%), ...

Abstract Psocids are damaging stored-product pests. In this study, eggs and early-instar nymphs, adults, all life stages of Liposcelis entomophila, L. decolor, bostrychophila, paeta were subjected to 43, 50, or 75% (Control) relative humidity (RH) for 2, 4, 6, 8, 10, 12, 14, 16 d at 30.0°C. All adults these species died within 8 both 43 50% RH, except which required 12 RH 100% mortality occur. ...
