“…Fawki et al (2012) also found that the smooth surface was preferred by the female pulse beetle for oviposition. Similar results were also recorded by Sharma and Thakur (2014) who worked with cowpea, soybean and chickpea genotypes and found that the cowpea and soybean genotypes have smooth testa and they are highly preferred for egg laying by the pulse beetle than the chickpea genotypes with rough testa. Tripathi et al (2013) observed that the colour and shape of cowpea seeds had no influence on the susceptibility of cowpea accessions to the pulse beetle.…”

Background: Cowpea is an excellent host for Callasobruchus maculatus (F.). These beetles cause havoc in stored cowpea. They have the habit of cementing their eggs to the surface of the host seeds. Hence, the present study was aimed to the find the influence of morphological characters of cowpea varieties/genotypes on oviposition of the pulse beetle. Methods: The ovipositional preference of C. maculatus on 14 cowpea varieties/genotypes was studied under the free choice condition and the data thus obtained were correlated with the morphological characters like seed shape, colour and texture. Result: Each variety/genotype had a significant effect on egg laying by C. maculatus. Significantly least oviposition was noticed in GC 3 (35.33 eggs), having a rough testa texture and greater number of eggs were found on GC 1612 (117.33 eggs) having smooth texture. The pulse beetle preferred smooth textured seeds for egg laying irrespective of its shape and colour. This was again confirmed by one of the genotypes GC 1702, which belongs to the Holstein group based on the eye pattern of the cowpea, in this genotype the pulse beetle preferred to lay eggs on the smooth brown portion surrounding the hilum than the wrinkled white portion.

“…The percent seed weight loss observed in this study was higher than the reported loss by Sharma and Thakur (2014a), which was 4.93%. Reports on losses due to bruchid damage vary from crop to crop (Sharma and Thakur, 2014b;Ebinu et al, 2016) and genotype to genotype (Sharma and Thakur, 2014c;Gevina et al, 2016). For example, common beans in Malawi have been reported to incur losses of up to 38%, Uganda reported up to 8%; while Kenya and Tanzania reported as high as 78% within six months of storage (Kananji, 2007).…”

Soybean (Glycine max (L.) Merrill) is among the major food and industrial crops grown globally for its high protein and oil content. Lately, in Uganda, soybean reportedly faces challenges with a storage pest, Callosobruchus chinensis. This study was carried out to quantify the damage caused by the pest and identify the sources of resistance in the germplasm in Uganda. The study was conducted at Makerere University Agricultural Research Institute, Kabanyolo (MUARIK) in Uganda, during 2015 and 2016. Callosobruchus chinensis was used to challenge 498 soybean lines under no choice condition, in the laboratory. Results showed no significant differences in eggs laid amongst the different genotypes; however the genotypes performed significantly different (P< 0.05) for adult insect emergence, median development period (MDP), Dobie susceptibility index (DSI), growth index (GI), insect percent emergence (% IE) and seed weight loss (%WL). Genotype AVRDC G8527 had the lowest % IE (6.31), DSI (0.7), % WL (0.02) and GI (0.07), suggesting high resistance. Weight loss of up to 27% was recorded in genotype USA 7. There was a strong positive correlation between number of adults that emerged with DSI (r=0.87), eggs (r=0.88), % weight loss (r=0.73), and growth index (r=0.996). Cluster analysis revealed that AVRDC G8527, a resistant genotype was closely related to S-line 13.2A, a moderate resistant genotype. Regression analysis, revealed that adult bruchid emergence explain seed weight loss with 62% coefficient of determination; while seed colour could be used to determine genotype DSI with up to 74% coefficient of determination. Genotypes AVRDC G8527 and G89 were identified as the most resistant genotypes based on levels of DSI.

“…Higher percentage seed weight loss with higher susceptibility index found in susceptible mungbean genotypes rather than resistant genotypes. The seed weight loss due to bruchid attack varies from variety to variety (Gevina et al, 2016;Sharma and Thakur, 2014a) and crop to crop (Ebinu et al, 2016;Sharma and Thakur, 2014b). Higher percentage of seed weight loss (78%) has been recorded in common bean during six months of storage condition (Kananji, 2007).…”

Background: Mungbean is an important pulse crop due to its high protein content. Bruchid is a major storage pest which causes deterioration of seed quality as well as quantity. The grain losses directly affect the agricultural economy and also the human health. Therefore, this issue has to be addressed with high priority. Methods: To address this issue, we have initiated a study to screen the fifty-two mungbean genotypes against the bruchid attack. The initial phase of the experiment was carried out from 2015 to 2017 in the department of Genetics and Plant Breeding, University of Calcutta to the laboratory condition through the no choice test. Result: Using the parameter bruchid susceptibility index according to Dobie, four resistant, ten susceptible, seventeen moderately resistant and twenty-one moderately susceptible mungbean genotypes were identified. The host resistance genotype HUM-8, PM-11-51, APDM-84, VC-639 are identified as the most promising resistant genotype.
