The pupal stage lasts about six days. 1991, Adebayo and Anjorin 2018). Small, brown, wartlike or blisterlike spots are found on pods damaged by curculios. On a day when the bounty of summer vegetables were heaped in farmer's stalls, Amanda Chester was on the hunt for one thing. Clearly, after a heavy infestation of weevils, the vine becomes yellowish, and this mark as symptoms of weevil infestation [22-24] (Figure 1). Diop, Y. M., E. Marchioni, D. Ba, and C. Hasselmann. Caswell G. H. 1968. J Agric Technol, 7(4): 1169-1175. are important pests of pulses. Depending on the region, the decrease in cowpea production by cowpea weevils can exceed 70% during a six-month storage period. Biology and life cycle. Callosobruchus maculatus is a serious economic pest of stored legumes and seed infestation starts in the field. Eggs laid by females hatch in 5 to 20 days. (Tuda et al. The female deposits her eggs on the outside of the bean. Omitogun, O. G., L. E. N. Jackai, and G. Thottappilly. The adults, which are seldom seen, are brown beetles with creamy stripes, 5mm and long feed on leaves and the grubs or larvae feed on the roots. Female Callosobruchus maculatus mating with multiple virgin males live longer, lay more and larger sized eggs throughout life (Wasserman and Asami 1985, Fox 1993) than females mating only once. Cowpea Curculio Biology. 1964. Fetoh, B.E.A. Seal, Dakshina R The entire life cycle . Oigiangbe, N. O., and A. O. Onigbinde. 2006. Key words: Adult emergence, egg hatchability, insect growth regulating . Zhu, K., J. E. Huesing, R. E. Shade, R. A. Bressan, P. M. Hasegawa, and L. L. Murdock. You will easily be able to tell the two apart, as the southern cowpea weevil is a flattish beetle that tends to be brownish black in coloration. Coleoptera: Bruchidae. A: There is another pest that has the common name of bean beetle. Stored Prod. Fox, C. W. 1993. Mitchell, R. 1975. The application of a low dose of 20 Gy can induce semi-sterility in adults of Callosobruchus maculatus (Ibrahim et al. Like the pea weevil, the damage is caused by the grub-like larva. Evaluation of powdered fruits of four peppers (Capsicum spp.) The infestation of the crops starts in the field (Prevett, 1961), while most damage occurs during storage. Cowpea Curculio Management. 2006). 2006, Resistance of Callosobruchus maculatus (Fab.) The adults do not require food or water and spend their limited lifespan (1-2 weeks) mating and laying eggs on beans. Punctures from feeding result in small malformed peas, and the results of egg laying are many legless grubs that destroy developing peas. Storage of the cowpea grain in the sealed metal drum (Seek and Gasper 1992) and the use of triple plastic bagging provided effective control over Callosobruchus maculatus infestation. Callosobruchus spp. The most critical variables influencing the generation time from egg to adult are temperature and relative humidity while rearing Callosobruchus maculatus on the preferred host (Howe and Currie 1964, Schoof 1941). The cowpea curculio is a small (4.8-5.5 mm in length), shiny, dark weevil with deeply pitted elytra and a . (2011) reported the lethal time for eggs, larvae, pupae, and adults at 42áµC were 18, 57, 78, and 71 h respectively and at 0áµ were 3, 8, 10, and 4 days. Weevil Life Cycle. Caption: Pea and bean weevil make characteristic notching round the leaf edges Q Does pea and bean weevil cause serious damage? The cowpea weevil, Callosobruchus maculatus (F.), is a storage pest that mainly infects cowpea (Vigna unguiculata (L.) Walp), spending part of its life cycle inside the grains. If beans are stored in a warm, humid place, the life cycle can be completed in as little as three weeks. The cowpea wevil, Callosobruchus maculatus is a major pest of economically important leguminous grain, such as cowpeas, lentils, green gram, and black gram.

Expression of a lifeâhistory tradeâoff in a seed beetle depends on environmental context. Appl. For additional information, contact your local Texas A&M AgriLife Extension Service agent or search for other state Extension offices. The entire life cycle (egg, larva, and pupa) takes place inside the kernel, and the insect can survive only when whole kernels are present. The eggs take between four and six days to hatch. Description and Life Cycle. After a week or two, the cowpea weevil will emerge out of the legume as an adult completing their life cycle in as little as 21 days. LIFE CYCLE: ¢ Life cycle completed in four weeks at 35°C and seven weeks at 22°C. The life history of both morphs is different with regard to their morphology, physiology, and behavior. 1979. The larvae stay inside the bean during the entire life cycle and emerge as adults. Applied Entomology and Zoology 34(4):.547-550. Cowpea Weevil (Callosobruchus maculatus) Warehouse & Cabinet Beetles (Trogoderma spp. Khan, Rafia. Six or seven generations may occur per year. Life cycle 30-50 days Feeds on any grain or processed grain product including oats, pet foods, seeds, dried fruits, rice, grain meals, Gomes, V. M., A. E. A. Oliveira, and J. XavierâFilho. This last abdominal segment also has two black spots visible. Evolutionary diversification of the bean beetle genus Callosobruchus (Coleoptera: Bruchidae): traits associated with storedâproduct pest status. Different botanical extracts exhibited the insecticidal activity on Callosobruchus maculatus (Sanon et al. There are at least two other species of thrips . Upon maturity, the larvae pupate near the surface of the bean and then emerge from the bean leaving numerous holes in the bean. Sterilizing insects with ionizing radiation. (2017) found the microwave radiation (240 W microwave power level at frequency 2450 MHz for 120 and 150 s) was lethal to Callosobruchus maculatus. soil. Habitat and Food Source(s): Mouthparts are for chewing. Freeze any suspect items at zero degrees Fahrenheit for six days. J. The life cycle of cowpea weevil contains four stages: egg, four larval instars, pupa, and adult [6,7,8]. 2001. . They also found the bablah (Acacia arabica L.) ash is more effective than the powdered leaves of nishinda, eucalyptus, and bankalmi. These weevils develop best in cowpeas (black-eyed peas) but may develop in a few other types of beans, such as chickpeas and lentil beans. Ilboudo et al.

Proceedings of Ghana Science Association 26: 14-18. "The Southern cowpea weevil is a storage pest, and a stored seed feeder, just like the pea weevil is," said Dr. Gadi V.P. Larvae typically develop inside the dried peas. Ketker, C. M. 1989. COMMERCIAL SERVICES. are laid in the flower buds and . In this study, we intended to determine whether elevated CO2 (at a biologically achievable level) has an enhanced suppressive effect over low O2 atmosphere alone on the cowpea bruchid (Callosobruchus maculatus), a storage pest of cowpea and other legumes. Infestation may start in the pods before harvest and carry over into storage where substantial losses may occur. 1996, Omitogun et al. 2010). Radiation disinfestation of cowpea seeds contaminated by Callosobruchus maculatus. 2009). 1996. It is a member of the leaf beetle family, Chrysomelidae, and not a true weevil.This common pest of stored legumes has a cosmopolitan distribution, occurring on every continent except Antarctica. Keywords: biology, instar, relative humidity, morphometric measurement, Callosobruchus maculatus. fumigation with pure essential oils and aromatized kaolin powders, were carried out on adults and eggs. Transportation often plays an important role in the movement of this pest. They prefer dried cowpeas . Scientific Name: Callosobruchus maculatus (Fabricius) 2018. Insect pests of cowpeas in Africa: their life cycle, economic importance, and potential for control. In the female, the plate is large and colored black on the sides with a white longitudinal line, while in the male, it is smaller and lacks strips. Female adults lay and glue eggs on seed surface of host plants. ideal weather conditions, the life cycle is about 25 to 35 days. The use of gamma-irradiated sub sterilized males in over flooding ratio can stop the multiplication of been beetle.

Integrated approach to the use of controlled atmospheres for insect control in grain storage. These pantry pests can include the grain weevil, rice weevil, cowpea weevil, strawberry root weevil and the bean weevil. 1996. The life cycle for this insect from egg to adult requires approximately 30-40 days. Cowpea weevils have only one such tooth. Shaaya, E., M. Kostjukovski, I. Eilberg, and C. Sukprakarn.
