In the present review article various control methods for stored grain insects are discussed in detail and an emphasis was made to use non-chemical methods. Stored grain infestation is a very serious problem as various life stages of insects cause economic damage and deteriorates the quality of food grains and food products. There are number of stored grain insect pests that infest food grains ...

currently, chemical pesticides and radioactive rays are widely used for control of stored product pests. fumigation plays a major role in insect pest elimination in stored products. phosphine and methyl bromide are the two common fumigants used for stored-product protection world over. insect resistance to phosphine is a global issue now and control failures have been reported in field situatio...

bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

Pest insects have a profound negative impact on agriculture and human health. Significant global losses of crops, stored agricultural products, timber and livestock can be attributed to damage and destruction by insects . Blood-feeding insects such as mosquitoes, flies and ticks transmit many of humanity's most devastating infectious diseases. Insect-borne diseases account for more than one mil...

Insects of the family Dermestidae are common insect pests of museums and other sites where historical artifacts are displayed and stored. Trogoderma variabile (Ballion), the warehouse beetle, is a member of this family, and though it is more commonly associated with processed and finished stored food products, it can be found in museums. There are aspects relating to monitoring and control of T...

essential oil extracted from the leaves of myrtle, myrtus communis l. (myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (tribolium confusum and callosobruchus maculatus). the chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (gc-ms). the major oil components were α-pinene (10.4%), α- terpineol (10.1%), linalool (9.0%...

effect of controlled atmospheres (cas) at various concentrations of co2, n2 and o2 on the lethal times of tribolium castaneum and trogoderma granarium was investigated at 20 and 30 ºc. experiments were performed using a recirculatory multi-flask apparatus. the results revealed that, the shortest times (0.1, 0.3 and 0.9 day for adults, larvae and pupae, respectively) required to obtain 50% morta...

Maize grain of hybrid AN 447 was: (a) infested with Sitophilus zeamais and infected with Aspergillus chevalieri; (b) infested with S. zeamais; (c) infected with A. chevalieri; and (d) grain free of insects and fungus (control); the treatments were stored for 30 days at 268C and 15% moisture content, under hermetic and non-hermetic conditions to monitor the oxygen concentration, insect mortality...
