“…The results regarding the incubation period of S. cerealella agreed with those achieved by Saikia et al (2014), who reported incubation periods of 2.8 ± 0.8 and 3.3 ± 0.5 days for S. cerealella reared on maize and rice, respectively. The developmental time of whole larval and pupal stages of S. cerealella, in this study, is not in agreement with the findings of Shukle & Wu (2003), who noted that the developmental time of the Fig. 6.…”

The life history and digestive α-amylase activity of the Angoumois grain moth, Sitotroga cerealella Olivier (Lepidoptera: Gelechiidae) were studied on six wheat cultivars (Arg, Bam, Nai 60, Pishtaz, Sepahan and Shanghai) at 25 ± 1°C, relative humidity of 65 ± 5% and a photoperiod of 16:8 (L:D) h. A delay in the developmental time of S. cerealella immature stages was detected when larvae were fed on cultivar Sepahan. The maximum survival rate of immature stages was seen on cultivar Bam (93.33 ± 2.10%), and the minimum rates were on cultivars Nai 60 (54.66 ± 2.49%) and Sepahan (49.33 ± 4.52%). The highest realized fecundity and fertility were recorded for females which came from larvae fed on cultivar Bam (93.30 ± 2.10 eggs/female and 91.90 ± 3.10%, respectively); and the lowest ones were observed for females which came from larvae fed on cultivar Sepahan (49.30 ± 4.50 eggs/female and 67.4 ± 11.1%, respectively). The heaviest male and female weights of S. cerealella were observed on cultivar Bam (2.97 ± 0.02 and 4.80 ± 0.01 mg, respectively). The highest amylolytic activity of the fourth instar was detected on cultivar Bam (0.89 ± 0.04 mg maltose min-1), which had the maximum mean hundred-wheat weight (5.92 ± 0.19 g). One α-amylase isozyme was detected in the midgut extracts from the fourth instar larvae fed on different wheat cultivars, and the highest intensity was found in larvae fed on cultivar Bam. Correlation analyses showed that very high correlations existed between the immature period, fecundity and fertility on one side and inhibition of α-amylase, soluble starch content and hundred-wheat weight on the other. According to the obtained results, cultivar Sepahan is an unfavorable host for the feeding and development of S. cerealella.

“…On injecting CLIK-148 into fifth instar H. armigera larvae, a significant decrease in molting was seen (Liu et al, 2006). Also, pepstatin A was able to partially inhibit the midgut proteases in Sitotroga cerealella and P. xylostella (Kumar et al, 2012;Shukle and Wu, 2003).…”

“…Plant seeds are a rich source of inhibitors, which have been described as endogenous regulators of proteolytic activity (Ryan, 1991) and as storage proteins (Xavier-Filho, 1992). Plant proteinase inhibitors have also been described as natural plant defence agents (Shewry & Lucas, 1997;Shukle & Wu, 2003). The proteinase inhibitors play an important role in regulating many physiological processes such as inflammation, coagulation, fibrinolysis, complement-activation intracellular protein breakdown, the cell cycle, transcription and apoptosis (Silverman et al, 2001).…”

A Kunitz-type trypsin inhibitor purified from the seeds of Murraya koenigii has been crystallized by the sitting-drop vapour-diffusion method using PEG 8000 as the precipitating agent. The crystals belong to the tetragonal space group P4 3 2 1 2, with unit-cell parameters a = b = 75.8, c = 150.9 Å . The crystals contain two molecules in the asymmetric unit with a V M value of 2.5 Å 3 Da À1. Diffraction was observed to 2.65 Å resolution and a complete data set was collected to 2.9 Å resolution.
