Abstract
Tribolium castaneum is a major storage
insect pest that infests a variety of food commodities, including cereals and
dry fruits. The present study aimed to determine its preferences among three
major cereal grains: wheat (Triticum aestivum), maize (Zea mays)
and rice (Oryza sativa). The experiments were conducted under ambient
laboratory conditions (30.5±3°C and 65±5 RH) and beetles were allowed to
complete their bionomics among different cereal grains. The population growth
index of the insect was also measured among cereal grains. Results revealed
that wheat grains were significantly preferred by the insect, exhibiting the
shortest duration of the development period (29.85 days) and the highest growth
index (2.329). Rice grains occupied the second position with a development
period of 31.82 days and a growth index of 2.026. However, maize grains were
found to be the least preferred compared to wheat and rice, having a
development period of 33.52 days and a growth index of 1.845, respectively.
