The present experiment was conducted using 17 different varieties of wheat to determine their susceptibility to Trogoderma granarium Everts at Maharaj Singh College, Saharanpur (U.P.), India during 2022 and 2023. The experiment was laid out in a completely randomized design with three replications in a control temperature of 27±2 °C and 70±5% relative humidity. Twenty-five newly hatched larvae were introduced in each jar (6 x 9 cm) containing 100 g of different varieties of wheat grains. Varieties were evaluated on the basis of percent adult emergence, longevity of adults, and growth index. None of the wheat varieties were recorded resistant to the test insect T. granarium. However, on the basis of different parameters, these varieties are being presented in ascending order i.e., P.B.W. 373 (5.89), P.B.W. 502 (5.91), D.B.W. 303 (6.56), W.H. 542 (7.90), U.P. 2565 (8.27), U.P. 2554 (8.43), H.D. 2967 (8.75), W.H. 533 (8.78), D.B.W. 16 (9.49), U.P. 2425 (9.54), H.D. 3236 (9.57), U.P. 2526 (9.84), P.B.W. 226 (10.04), U.P. 2382 (10.22), P.D.W. 291 (10.36), D.B.W. 17 (11.25) and P.B.W 343 (13.27). So, it is clear that P.B.W. 373, P.B.W 502, D.B.W 303, W.H. 542 were found less susceptible while U.P. 2554, H.D. 2967, W.H. 533, D.B.W. 16, U.P. 2425, H.D. 3236, U.P. 2526 were moderately susceptible, whereas P.B.W. 226, U.P. 2382, P.D.W. 291, D.B.W. 17 and P.B.W. 343 were among the most susceptible varieties.

During the months of Feburary-March 2007, infected and diseased samples of cashewnuts were collected from the Kerala district of India in and around Cochin and Ernaculum. Severe damage of the nuts was observed due to the insect Trogoderma granarium which feeds on the entire soft portion of the kernel. The nuts were also observed to be infected by a fungal organism Alternaria geophila which made this nutritious nut unfit for human consumption. [ABSTRACT FROM AUTHOR]
