“…The adult C. maculatus males and females both have an average life span of 7 days under laboratory conditions and only a few can survive more than 2 weeks ( Fatima et al, 2016 ). The oviposition by C. maculatus reaches a peak within 2 days after the commencement of oviposition and declines over time ( Barde et al, 2014 ). Each female lays about 100 eggs.…”

Mungbean [Vigna radiata (L.) R. Wilczek var. radiata] is an important pulse crop in Asia, and is consumed as dry seeds and as bean sprouts. It is an excellent source of digestible protein. Bruchids [Callosobruchus chinensis (L.) and Callosobruchus maculatus (F.)] are the important pests of mungbean and cause damage in the field and in storage. Bruchid infestation reduces the nutritional and market value of the grain and renders seeds unfit for human consumption, agricultural and commercial uses. These pests are controlled mainly by fumigation with highly toxic chemicals such as carbon disulfide, phosphene, and methyl bromide, or by dusting with several other insecticides, which leave residues on the grain, thus, threatening food safety. Some plant-based extracts have been found useful in controlling bruchids, but are not fully successful due to their short-term activity, rapid degradability, and potentially negative effect on seed germination. Although some wild sources of bruchid resistance in mungbean have been reported, which have been used to develop bruchid- resistant lines, undesirable genetic linkages threaten the proper exploitation of genetic diversity from wild germplasm into commercial cultivars. Further, biotype variation in bruchids has rendered some mungbean lines susceptible that otherwise would have been resistant to the pest. Host plant resistance is a cost-effective and a safe alternative to control bruchids in mungbean and is associated with morphological, biochemical, and molecular traits. These traits affect insect growth and development, thereby, reduce the yield losses by the pests. Understanding the defense mechanisms against insect pests could be utilized in exploiting these traits in crop breeding. This review discusses different traits in mungbean involved in defense against bruchids and their utility in pest management. We also highlight the breeding constraints for developing bruchid-resistant mungbean and how can these constraints be minimized. We further highlight the importance of supporting conventional breeding techniques by molecular techniques such as molecular markers linked to bruchid resistance.

“…The females of C. maculatus oviposit on the surfaces of legume seeds and pods. Oviposition reaches a peak within 2 days and declines thereafter till the non-feeding female stops egg laying and dies around the eighth day (9) . The larvae hatch out in about 5 days and bore into the seeds beneath the oviposition site and complete their development within the respective grains.…”

Background/Objectives: The toxic synthetic pesticides must be replaced by safe, cheap, non-toxic, target-specific insecticides such as natural plant products. This study is to investigate the ovipositional and eclosion inhibitory activities of five plant products against the pulse beetle, Callosobruchus maculatus infesting green gram (Vigna radiata). Method: Fine powders prepared from various parts of the plants Piper longum, Adhatoda vasica, Illicium verum, Cinnamomum zeylanicum and Syzygium aromaticum at various concentrations (0.2, 0.4, 0.6, 0.8 g) were added to 30 g of V. radiata seeds and two pairs of adult C. maculatus were introduced. Inhibitory effect of oviposition was studied by counting the number of eggs periodically (24, 48, 72, 96 and 120 hours) and the eclosion failure was also assessed. The control was similar to the experimental setup except for the absence of plant powders. Findings: The oviposition deterrence values which provide a comparison between the control and treatments showed S. aromaticum to be the strongest deterrent with a value of 85.77 followed by C. zeylanicum (76.33), P. longum (66.91), I. verum (62.96) and A. vasica (42.93) at 0.8 g. Also S. aromaticum recorded the highest eclosion failure of 22.06% and the lowest with A. vasica (11.08%) at 0.8 g. Statistical analysis showed an overall significant difference (p < 0.05) between the different plants, concentration wise. Though all the five selected plants exhibited insecticidal activity, S. aromaticum was the strongest in inhibiting oviposition and impairing larval growth of C. maculatus. Novelty: Previous works have demonstrated the insecticidal activity of the essential oils of S. aromaticum and C. zeylanicum but this study has shown that prepared powders of both these spices are quite effective at low concentrations, so can be easily used by farmers.
