Warlier insects were identified on morphological characters, now many molecular and similar tools are available to reduce ambiguity and correct identification of the species. In this regard if you come across any publications please kindly share.
Hi Harish,
You can find out useful information through the links below (four articles) about molecular approaches used to identify some stored grain insects:

The following are a few of my many papers on use of cuticular hydrocarbons to identify difficult members of closely related species. These are often mis-identified, and colonies often become changed inadvertantly, as we found in commercial parasitoid colonies. Little DNA efforts have been ,made for some groups. But the hydrocarbons analyzed by inexpensie fast high resolution Gas Chromatography are usually good for this purpose. We worked on a host of insects, honeybees, parasitoid wasps, rare and exotic cockroaches, all 27 spp of tsetse flies. and many others including moths and beetles. Most all species are loaded with unique protective hydrocarbons, but not ticks! Here are a few references/
