Bioefficacy of some plant derivatives that protect grain against the pulse beetle, Callosobruchus maculatus

Abstract

Experiments were conducted to study the bioefficacies of different plant/weed derivatives that affect the development of the pulse beetle, Callosobruchus maculates F. (Coleoptera: Bruchidae) fed on black gram, Vigna mungo, seeds. Plant extracts, powder, ash and oil from nishinda (Vitex negundo L.), eucalyptus (Eucalyptus globules Labill.), bankalmi (Ipomoea sepiaria K.), neem (Azadirachta indica L.), safflower (Carthamus tinctorius L.), sesame (Sesamum indicum L.) and bablah (Acacia arabica L.) were evaluated for their oviposition inhibition, surface protectant, residual toxicity and direct toxicity effects on C. maculates. The results showed that plant oils were effective in checking insect infestation. The least number of F1 adults emerged from black gram seeds treated with neem oil. The nishinda oil extract was the most toxic of three extracts tested (nishinda, eucalyptus and bankalmi). Bablah ash was the most effective compared to the powdered leaves of nishinda, eucalyptus and bankalmi. The powdered leaves and extracts of nishinda, eucalyptus and bankalmi, at a 3% mixture, provided good protection for black gram seeds by reducing insect oviposition, F1 adult emergence, and grain infestation rates. The oil treatment did not show adverse effects on germination capability of seeds, even after three months of treatment.

“…Ipomoea sepiaria (I. sepiaria), an important ethanomedicinal plant [7], onsidered as a source plant in classical Ayurvedic drug Lakshmana known for the treatment of leucorrhoea and infertility [8]. Aqueous hot water extract of Bankalmi (Ipomoea sepiaria) is also efficiently used in the control of hispa beetle [9], bean aphid Aphis craccivora Koch [10] , pulse beetle -Callosobruchus maculates [11]. Etc.…”

Efficacy of two plant powders as cowpea grain protectants against <i>Callosobruchus maculatus</i> Fabricius (Coleoptera, Chrysomelideae: Bruchinae)

“…It is both field and stored pest. Infestation often begins in the field when pods are mature (Sathyaseelan et al, 2008) and when seeds are harvested and stored, the pest population increases rapidly and results in total destruction during short period of 3-4 months (Rahman and Talukder, 2006). Synthetic insecticides employed in the control of cowpea beetle Journal of Applied Biosciences 105:10152 -10156 ISSN 1997-5902 proved effective, very expensive and unavailable at critical periods and they sometimes constitute health hazards to consumers (Lale, 2002).…”

Evaluation of the insecticidal effects of <i>Hyptis suaveolens</i> (L.) for the management of <i>Callosobruchus maculatus</i> (F.) on two varieties of cowpea, <i>Vigna unguiculata</i> walp

“…It is a field -to-store pest as its infestation of cowpea often begins in the field as the mature pods dry (Huignard et al, 1985;Sathyaseelan et al, 2008) and when such seeds are harvested and stored, the pest population increases rapidly and results in total destruction within a short duration of 3-4 months (Rahman and Talukder, 2006). It multiplies very rapidly in storage and has caused 8.5% loss in pulses during postharvest handling and storage in India (Ouedraogo et al, 1996).…”
