The life cycle and season’s studies of Tribolium castaneum indicated that the most favourable season as monsoon (27±5<” C & 80±05 % RH) where they have completed their life cycle within 22 days. The most unfavourable season was the winter (15±3<” C & 35±05 % RH) where it extended till 45 days. Results showed the presence of seven larval instars in the life cycle of the beetle. Stereomicroscope was used to study the microscopic stages like eggs, sexual dimorphism of pupae and adults, morphometric of the beetle. This is the first compiled stereomicroscopic photographs of the life cycle of T. castaneum.

Research studies were carried out to evaluate insecticidal action of two plant products and a synthetic insecticide on a major stored-product insect, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The plant species studied were, Piper nigrum and Eucalyptus camaldulensis, whereas methoprene used as synthetic insecticide. Two formulations viz., powder and ethanol extract of each plant and four concentrations (5ppm, 10ppm, 15ppm and 20 ppm) of methoprene were tested. Repellency was tested using the filter paper test whereas mortality, weight loss protection and anti-feedant potential of all treatments was evaluated by using whole maize grains. Our results were highly significant as compared to control however; P. nigrum was more effective as compared to E. camaldulensis. The investigation of cumulative effects of botanical and synthetic insecticide and isolation of active ingredients of botanicals are further issues to be investigated for their inclusion in. I. P. M programs.

The relative position of the genes black (b), light ocular diaphragm (lod) and aureate (au) for the third linkage group of T. castaneum (Herbst) (Coleoptera, Tenebrionidae) has been determined as b – lod – au. The distances between the various genes vary, depending on the cross. The b++/+ lod au ♂ × + lod au/+ lod au ♀ crosses give the following recombination values: au – lod = 18.32 ± 1.21%; b – lod = 21.05 ± 1.51% and b – au = 37.43 ± 1.27%. The reciprocal crosses give au – lod = 27.67 ± 1.62%; b – lod = 13.97 ± 1.26% and b – au = 39.79 ± 1.78%. For the larger distances encompassed in the b – au region the recombination values in the two sexes were not significantly different. For the shorter b – lod region the recombination values were significantly larger in the females than in the males, while for the adjacent lod – au region the opposite was true. On the basis of the current literature it would appear that the main factors contributing to these sex differences in recombination are the modifiers which are different in the genetic background of the two sexes.
