A total of 51 accessions of different Lens spp. viz., Lens culinaris (cultivated) and L. culinaris subsp. odemensis, L. culinaris subsp. orientalis, L. orientalis, L. nigricans, L. lamottei and L. ervoides (wild species) were screened for their reaction to Callosobruchus chinensis under no-choice artificial infestation conditions to find the sources of resistance. Significant differences among the accessions in terms of number of eggs laid, development period, adult emergence, number of emergence holes of C. chinensis loss in seed weight on different Lens spp. were observed. Of the seven species tested, L. culinaris was the most preferred one for egg laying while L. ervoides was the least preferred. Based on Growth Index (GI), accessions were categorised as highly resistant (15 accessions, GI = 0.00), resistant (14, GI=0.00 to 1.00), moderately resistant (16, GI=1.01 to 2.00) moderately susceptible (3, GI 2.01 to 3.00) susceptible (3, >3.01) to C. chinensis and the species have been arranged in the order of their resistance to C. chinensis. viz L. ervoides > L. lamottei > L. nigricans= L. orientalis > L. culinaris subsp. orientalis= L. culinaris subsp. odemensis > L. culnaris, i.e. L. ervoides was highly resistant and L. culnaris was the most susceptible. Correlation between GI and growth parameters of pulse beetle on different Lens spp. accessions indicated that GI had negative relationship with mean development period (-0.22) and significant positive relationship with adult emergence (+0.73), weight loss (+0.77) and eggs laid (+0.75).

Background: The pulse beetle, Callosobruchus chinensis L. is one of the main biotic threats to chickpea in both field and storage in the world. The evaluation of chickpea genotypes for pulse beetle resistance has increased motivation for the identification and application of host plant resistance as a critical component of pest management. Methods: In the present study, different chickpea genotypes were evaluated under laboratory conditions to identify the antixenosis, antibiosis and GC-MS based untargeted metabolomics of promising chickpea genotypes to the C. chinensis. Result: Genotype NBeG1004 (36.61 eggs/100 seeds) was less prone to egg laying, while ICCV14872 (180.45 eggs/100 seeds) was the most preferred. However, maximal developmental periods, minimum per cent adult emergence and growth index was observed in ICCV92944 Genotype HC1 showed substantial resistance with maximum phenolic, flavonoid and protease inhibitors content. The results revealed that presence of 9-Octadecenoic acid (Z) in HC1 conferred resistance to C. chinensis. These results show assurance for incorporation into an IPM program against C. chinensis.

Eleven chickpea varieties were screened for their biochemical resistance to the pulse beetle (Callosobruchus chinensis L.), a serious pest of the stored pulses. The varieties were found to arrest the growth and development of C. chinensis, at grub stages which were indicated by different parameters viz., oviposition, adult emergence, weight loss, developmental period and growth index. Among the various biochemical analyzed, high growth index was observed in the varieties PKG 2 (0.61), BG 1003 (0.62), BG 1053 (0.62) and PKG 1 (0.71). Low growth index recorded in PG 3 (0.52), BGM 547 and PG 186 (0.56) may be attributed to low phenol and tannin content. Similarly the varieties PKG 1, BG 1003 and BG 1053 with less phenol, flavonoids and tannin content recorded more growth index as compared to moderate resistance varieties PG 4, PBG 1 and PG 114 PBG 1, BGM 547 and PG 114 were found to be moderately resistant and PKG 1, PKG 2, BG 1053 and BG 1003 as highly susceptible, shows the major role of trypsin inhibitor in protein resistance to C. chinensis. The highest protease activity inhibition acts as antimetabolites to C. chinensis, inhibit to the feeding of grubs as result higher trypsin content varieties showed relative resistance. The correlation between different antinutritional factors and growth index of the grub also showed a negative relationship.

Experiments were carried out in the laboratory to assess the effectiveness of Nogos, Malathion, Sevin and Limper on lentil, gram, grasspea, greengram and blackgram seeds with eggs of pulse beetle, Callosobruchus chinensis L. Insecticides were sprayed on the seeds along with eggs and found that all the tested insecticides inhibited hatching of eggs resulting in significantly lowest rate of adult emergence. Nogos and Malathion recorded the lower number of emergent adults. The overall 26.35- 100% reduction of seed damage and 40-100% weight losses were achieved in insecticides treated seeds of five different types of pulses showing highest reduction in seed damage and weight losses due to Nogos and Malathion treatments. The treatment of the pulse seeds with the insecticides did not affect the seed germination. Key words: Insecticides, pulse beetle, egg treatment, pulses, seed damage.

Introduction: Post-harvest conservation remains a major challenge for most crops in developing countries. Among these is Cowpea one of the major legumes grown and consumed in the tropics and subtropics of countries. Callosobruchus maculatus infestations constitute are the most prominent threat for this particular crop. Objective: The present research aimed at evaluating the susceptibility of four cowpea varieties against infestations of C. maculatus. Place and Duration of Study: The study was conducted at the entomology laboratory of the cowpea section of the Regional Center for Agricultural Research of Maroua from November to December 2018. Methodology: The experiments were carried out based on the factorial experiment by randomized complete design with five replications. 40 seeds of each variety were put in contact with 5 pairs of bruchids. Results: The results show that the four cowpea varieties evaluated have different physical characteristics of the seeds. This variability would play an important role in inducing the ovipositional response of C. maculatus females. However, it is not enough on its own to explain the various degree of susceptibility to C.maculatus infestations. There was a positive perfect correlation between the number of adult emergence, growth index, weight loss, number of holes and Dobie susceptibility index. Also, BR-1 was found to be more resistant to C. maculatus followed by Lori-niébé, Vya and least resistance was observed in the Borno brown. The multiple regression analysis reveals that there is a negative relationship between mortality rate of developmental stages, weight loss, F1 offspring production, and seed susceptibility. Conclusion: The physical characteristics of the four cowpea varieties tested to affect the susceptibility of the grain to beetle attacks. A number of adult emergence, growth index, weight loss, and susceptibility index are the main indicators for the resistance of cowpea to C. maculatus damage. An analysis of the amino acids contained in the BR-1 is recommended for the introgression of its resistance alleles in susceptible varieties.

The experiment was conducted to find out the efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis on gram seed in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period of February to May, 2009. The concentrations of dodder vine extract were 5, 2 and 1% respectively. Efficacies of these treatments were evaluated by considering oviposition, adult emergence, intensity of damage and seed weight loss done by pulse beetle. Dodder vine extract was found effective in checking oviposition, adult progeny development and severity of seed damage. Seeds treated with 5% concentration of dodder vine extract were less preferred for oviposition, adult emergence and seed weight loss by C. chinensis and this conc. might be useful in protection of pulse seed.

The pesticidal efficacy of four locally available leaves of botanicals like neem (Azadirachta indica), datura (Datura stramonium),  marigold (Tagetes erecta) and garlic (Allium sativum L.) tablet powders was assessed on pulse bettle (Callosobruchus chinensis L) through adult mortality and emergence, oviposition performance, seed damage, weight loss and germination  of chickpea (Cicer arietinum). The above test biopesticides were tested at three different rates (0.5 g, 1.0 g and 1.50 g powder/kg of chickpea seeds). All the tested powder showed significant effect on the above parameters. The highest adult mortality was recorded when chickpea seeds were treated with datura leaf powder at 1.50 g/kg, whereas marigold showed the least effect on adult mortality. The powders used in the experiment effectively controlled oviposition and adult emergence of pulse beetle. The lowest number of adult emergence was obtained from chickpea seeds treated with datura leaf powder at 1.50 g/kg. The highest weight loss was observed in control seeds followed by marigold leaf powder 0.5 g/kg gram seeds. Datura leaf powder treated seeds showed the lowest seed weight loss followed by neem, garlic and marigold. Plant powders had profound effect on seed germination. The highest germination was observed in treated seed with datura leaf powder at 1.50 g/kg and the lowest germination in control seed followed by marigold leaf powder at 1.5 g/kg treated seeds. The pesticidal effect on oviposition, adult mortality, adult emergence, and seed weight loss was directly proportional to leaf powder rates.

The present study intends to screen 52 pigeonpea genotypes for bruchid infestation under controlled conditions using no-choice assay. The results revealed significant differences among the genotypes considering parameters like growth index (GI), egg numbers and adult emergence. The genotypes viz., ICP 89049, IPA 37 and Dholi dwarf DB had low average values for GI (0.45, 0.48 and 0.48 respectively), number of eggs after 20 days (14.5, 21.5 and 28), and adults emerged after 30 days of oviposition (9.0, 7.0 and 4.5, respectively) when compared to the genotypes Asha (higher GI: 1.10), and IPA 7–6 (having 98.0 eggs after 20 days of incubation). Concerning associations among different traits, the GI had significant positive correlations with number of eggs laid (0.484), and number of adults emerged at 15–30 days (0.638). The GI showed a negative relationship with proportion of seed coat (–0.162) and seed hardness (–0.197). The traits that are less preferred by the bruchids include hard seed with less seed diameter and high proportion of seed coat. The tolerant genotypes viz. ICP 89049, IPA 37 and Dholi dwarf DB identified here could be deployed in breeding programs for reducing post harvest losses in pigeonpea.

An experiment on eco-friendly approach of managing pulse beetle (Callosobruchus chinensis L.) in chickpea (Cicer arietinum L) was carried out at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal from April to July, 2007. The experiment consisted of fourteen treatments laid out in two factors Completely Randomized Design (CRD) with three replications. Among them, storage structure (aluminium sheet bin and jute bag with plastic lining) was considered as one factor and pesticidal materials (Xanthoxylum armatum DC fruit dust@ 30gm kg-1; Acorus calamus L. rhizome dust@ 30 gm kg-1; Cinnamom camphora balls@ 1.5 gm kg-1; Sesamum indicum L. oil@ 5 ml kg-1; Azadirachta indica A. Juss. leaf dust@30gm kg-1; malathion dust@ 1gm kg-1 and control) was as another factor. Among six pesticidal materials tested, mortality of adult bruchids was obtained significantly higher in chickpea treated by C. camphora balls (25.17) followed by A. calamus rizome dust (24.83) and Sesamum oil (24.50). Grain damage and weight loss was nil in chickpea treated by these three materials. Among botanicals used, X. armatum fruit dust and A. indica leaf dust were found ineffective to cause adult mortality (20.33 and 19.67) and adult emergence (1549 and 2292) in chickpea. Malathion, initially was found somewhat effective in adult mortality (21.67) and adult emergence (30.33). However, it was less effective from F2 generation resulting maximum adult emergence (2127). While comparing two storage structures, jute bag with plastic lining was better in terms of maintaining lower moisture (14.64%), higher germination (65.14%) and lesser grain damage (39.95%). Thus, the jute bag with plastic lining was found as a better storage structure and botanical materials such as A. calamus rhizome dust, Sesamum oil and C. camphora balls have been found as effective safe alternatives for the management of C. chinensis L. in the storage of chickpea.
