        Abstract

The susceptibility level of six wheat varieties (Seher-2006, Faisalabad-2008, Lassani 2008, AARI-2011, Punjab-2011 and Millat-2011) was determined against the life cycle parameters of Angoumois grain moth (Sitotroga cerealella) under laboratory conditions. Experiment was laid down in completely randomized design with three replications. The data were recorded on the basis of egg laying capacity, hatching percentage, larval survival, pupal survival, egg hatching period, larval period, pupal period and biochemical analysis of grains (Protein and Ash contents).The results revealed that none of the varieties was completely resistant against the attack of Sitotroga cerealella. Significant variations were observed in all six wheat varieties with regard to hatching percentage, larval survival, pupal survival, egg hatching period, larval period, pupal period and biochemical analysis of grains (Proteinand Ash contents). The infestation of Sitotroga cerealella was increased with high protein contents while high ash contents decreased the infestation of Sitotroga cerealella in wheat varieties. In all above mentioned parameter it was clear that Lassani-2008 variety found as a resistant against the biology of Sitotroga cerealella while Millat-2011 was most susceptible wheat variety because the infestation level of Sitotroga cerealella was high in this variety. However, wheat varieties Seher-2006 and AARI-2011 were moderately susceptible while Faisalabad-2008 and Punjab-2011 varieties were moderately resistant wheat varieties.

Abstract

Beneficial insect fauna is the beauty of the applied entomology that is being disturbed with the variable agro-ecosystem and climate unbalancing with human entrance as blind chemical pest management. Honey bees among beneficial forces are the superb pollinators that can enhance the yield of a crop up to fifty percent as even cross pollinated crops depends on this insect. Multiple factors are responsible to lessen down its population even ground to become a part of extinct species. Fuel odor, volatile chemicals or by products like nitric oxide and nitrogen dioxide, or NOx gases are not only lethal to bee’s body as well as interrupt their foraging. Memory impairment, disorientation, behavioral dilemma and somatic abnormalities observed when bees were forage on neonicotinoids unhygienic flora and acute toxic chemicals up to 7,000 times more than DDT. Predators and parasites like bees, ants, mites and beetles threatening bees especially Acarapis woodi is a serious pest reported from 20th Century. So there is need to protect these natural pollinators by using eco- friendly agricultural practices to harvest their products.
