Results of the evaluation on bioefficacy of three indigenous plant extracts for toxicity and residual effects against the pulse beetle, Callosobruchus chinensis L. (Bruchidae: Coleoptera) showed that the plant extracts had toxic and residual effects for controlling pulse beetle. Mortality and residual effects were statistically different among the plant extracts and doses applied. Neem extract showed the highest adult mortality (36.78%) whereas eucalyptus extract showed the lowest (22.75%). The order of the toxicity of three plant extracts was found as neem > custard apple > eucalyptus. Mortality was found directly proportional to the hour after treatments which increased with the progress of time. Between two solvents, acetone solvent possessed the highest toxicity (mortality 32.95%) but methanol showed the lowest toxicity (mortality 30.56%). The residual toxicity was evaluated on the basis of egg laid, adult emergence, seed infestation and weight loss caused by the insect. The highest residual toxicity was found in neem extract with acetone while the lowest in eucalyptus extract with acetone. Neem extract with acetone and custard apple extract with methanol solvent were found effective to toxic and residual effects against pulse beetle of three plant extracts applied. Asiat. Soc.

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.

There have been paradigm shift to the use of biopesticides as alternative to synthetic pesticides in recent years due to its environment friendliness and non-toxic to the non-target organisms. Therefore, three synthetic insecticides and water extract from neem back powder were evaluated on cowpea in the field and their residual toxicity tested against C. maculatus in the laboratory. The insecticides were applied at the rate of 2ml in 2L of water and 2L of extract from neem back powder on the field. The harvested seeds were infested with C. maculatus to evaluate the residual toxicity of the insecticides. Data on growth and yield parameters were taken on the field while data on adult mortality, oviposition, adult emergence and weight loss were recorded for the laboratory experiment. The results showed positive response of cowpea to the applied chemicals as they had higher values for the number of leaves, branches and reduced number of holes. Number of holes was significant (p< 0.05) at the 8th week with the control having highest number of holes. Cowpea treated with cypermethrin had highest number of pods at both 7th and 8th week and showed significant difference at 7th week. Highest weight of seeds per pod was obtained from the cowpea treated with water extract from neem back powder and was significantly different (p< 0.05) from other treatments. Seeds treated with the three insecticides had the same number of mortality while neem extract had highest but was not significantly different (p> 0.05). There was a reduction in number of eggs laid, adult emergence, seeds with holes and weight loss in the seeds treated with the four insecticide compounds. It was concluded that application of the insecticidal compounds positively enhanced the performance of cowpea on the field and could protect the seeds against C. maculatus in the laboratory. This study revealed that water extract from back powder of neem could be used as a botanical in the protection of cowpea against seed beetles.

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.

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.
