Pulses serve as one of the main sources of protein and minerals as well as play a vital socio-economic role in the diet of common people of Bangladesh but these pulses suffer enormous losses due to infestation of a serious insect pest pulse beetle, Callosobruchus chinensis L. As a part of eco-friendly management of this detrimental pest, an experiment was conducted at the laboratory to determine the toxicity of spinosad against the pulse beetle, C. chinensis L. directly by using dry film contact toxicity method and indirectly by treating chickpea seeds. In the direct method spinosad showed contact toxicity and the lethal concentration of spinosad was 117.46, 76.05 and 37.45 ppm at 24, 48 and 72 hours after treatment, respectively. On the other hand, the LC50 values were 990.34, 301.35 and 95.08 ppm after 24, 48 and 72 HAT, respectively as per indirect method. A dose-dependent relation with the mortality was observed by both methods. Spinosad was also significantly effective in reducing the number of eggs (68.00 to 98.60% inhibition over control), adult emergence (56.70 to 100% inhibition over control), percent seed infestation (62.79 to 100% inhibition over control) and seed weight loss (50.81 to 100% inhibition over control). The present results indicated that spinosad could be suggested for the efficient management of C. chinensis in storage. J. Bangladesh Agril. Univ. 16(3): 411–416, December 2018

The pulse beetle, Callosobruchus chinensis is one of the major insect pest in stored pulse (i.e. Chickpea seeds) causing 40-50% losses of pulses in storage. Experiments were conducted to study the efficacy of some selected biorational insecticides on mortality of beetle, weight loss of seeds, fecundity and hatchability of pulse beetle, Callosobruchus chinensis under laboratory condition. Among the different botanicals, Neem oil (89.00%) was found the most effective in case of mortality of pulse beetle in direct method followed by Mahogany oil (78.00%) and Karanja oil (62.00%). Among different microbial derivatives, Spinosad was found most effective considering mortality followed by Emamectin benzoate and Abamectin. Among botanicals the highest percentage of weight reduction was observed in Karanja oil (30.18%) and the lowest (22.43%) was in Neem oil while among microbial derivatives the lowest percentage of seed weight reduction was obtained from Spinosad (11.15%) and the highest percentage of weight reduction was obtained from Abamectin (20.37%). No. of eggs laid per female was recorded highest in Karanja oil (24.00) and lowest in Spinosad (19.33). The hatchability percentage was highest in Karanza oil (21.73%) and lowest in Neem (12.89%) and in case of chemical treatment lowest in spinosad (6.05%) and highest in Ebamectin (14.42%). Neem oil and Spinosad were found effective against pulse beetle in storage condition. Therefore, Neem oil and Spinosad might be included in the development of IPM packages for the management of pulse beetle in the storage.

Abstract Essential oil from Allium sativum was isolated and investigated for its repellent, insecticidal, ovipositional and egg hatching inhibition activities against pulse beetle, Callosobruchus chinensis (Coleoptera: Bruchidae). A. sativum essential oil repelled bruchid adults at a very low concentration in choice oviposition assay. A. sativum essential oil caused both fumigant and contact toxicity in C. chinensis adults in a concentration dependent manner. Oviposition potency of C. chinensis adults was reduced significantly when sublethal concentrations of A. sativum essential oil were applied by fumigation and contact method. In chronic toxic-ity assay, A. sativum essential oil reduced F1 progeny emergence, damage and weight loss in seeds. Findings of the present study suggest that A. sativum essential oil can be useful as promising agent in insect pest management programme.

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.

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.

The pulse beetle, Callosobruchus chinensis is one of the major pests in stored pulse causes 40-50% losses of pulses in storage. Experiments were conducted to study the efficacy of some selected biorational insecticides on percent mortality of beetle, percent weight loss of seeds, no. of eggs laid per female, percent hatchability, larval duration, pupal period and adult longevity of pulse beetle, Callosobruchus chinensis under laboratory condition. Among the different botanicals, neem oil (77%) was found the most effective showing 78% mortality of pulse beetle in direct method followed by Mahogany oil (69%) and karanja oil (62%). In case of indirect method, the highest percent mortality was recorded from karanja oil (37%) which was followed by Neem oil (33%) and Mahogany oil (33%). Among different microbial derivatives, Libsen was found most effective considering mortality followed by Suspend 5SG and Ambush 1.8EC. The highest percentage of weight reduction was observed in Karanja oil (15%) and the lowest (14%) was in Mahogany oil. The highest percentage of weight reduction was obtained from Ambush 1.8EC (16%) and the lowest percentage of weight reduction was obtained from Suspend 5SG (13%). No. of eggs laid per female was the highest in mahogany oil (24) and lowest in Libsen (19).  Percent of hatchability was highest in mahogany oil (21%) and lowest in Libsen (16%). Larval duration was the highest in mahogany oil (16 days) and the lowest was in Suspend 5SG(13days). Pupal period highest in neem oil (7 days) and the lowest was in (6 days). The highest adult longevity (22 days) from the seeds treated with karanja oil. The lowest adult longevity (18 days) from seeds treated with Libson. Thus, Karanja, Neem and Mahogany oil, Libsen, Ambush 1.8EC and Suspend 5SG were found effective against pulse beetle in storage. Therefore, these biorationals might be included in the development of IPM packages for the management of pulse beetle in the storage.
