[9][10][11][7], S. zeamais occurs throughout warm, humid regions around the world, especially in locations where maize is in storage, and Busseola fusca (Fuller), Sesamia calamistis Hmps. The type of food consumed by the larvae influences the size of the adult (3.9-4.9 mm on corn, 3.0-4.6 mm on wheat, 2.9-4.3 mm on rice, 2.7-3.2 on rough rice, and 2.3-3.9 mm on shelled rice). [7] The female chews through the surface of the grain, creating a hole. [6], The maize weevil and the rice weevil look very much alike but external features can be used to differentiate the vast majority of adults. [3] This species attacks both standing crops and stored cereal products, including wheat, rice, sorghum,[4][5][6] oats, barley, rye, buckwheat,[6] peas, and cottonseed. The insecticide effect and the effectiveness through time was evaluated of ten vegetal oils (sesame, almond, basil, peanut, canola, jojoba, laurel, lila, maize and soya), to control the Sitophilus zeamais in maize seed VAN-210 stored by 126 days. She then deposits a small oval white egg, and covers the hole as the ovipositor is removed, with a waxy secretion that creates a plug. A possible indication of infestation is grain, when placed in water, floating to the surface. The maize weevil (Sitophilus zeamais Motschulsky) is one of the most serious stored product pests that cause huge losses in the tropics (Mwololo et al., 2012). Journal of Stored Products Research, 39(2): 225–235. [7] This species has also been recorded in Canada, in the provinces of Ontario and Quebec,[6] and has been intercepted at ports, but is not well established there. This provides the only visible evidence that the kernel is infested. TOXICOLÓGICOS PARA EL CONTROL DE Sitophilus zeamais MOTSCHULSKY. It can breed in crops with a moisture content of a much wider range than S. oryzae, and has been found in fruit, such as apples during storage. Danho, M., Gaspar, C., Haubruge, E. 2002. ß%’¥ü8‘“–ÄÕ«‡_aÜüÊ Abril de 2009 The larvae will pupate while inside, then chew a circular exit hole,[1] and emerge as an adult beetle. during the 1st 8 weeks when maize is planted in the field. from Sitophilus oryzae (L.) (Coleoptera: Cuculionidae). The S. zeamais homologue of the Drosophila para VGSC was identified using degenerate primers and sequenced. It has, however, been present for several years in Montreal, where grain from the U.S. is stored.[12]. 2003. It can be found in numerous tropical areas around the world, and in the United States, and is a major pest of maize. (2003). Use of plant compounds in grain protection has shown great potential as an alternative to synthetic insecticides in Sub-Saharan Africa. Se llevó a cabo en el laboratorio el método del control biológico en arroz cáscara almacenado para evaluar su efectividad. Journal of the. It is also widely distributed throughout agricultural areas of northern Australia. ”]œˆ™Féœ [„††s4!†0àR*µY_Ëj„Œü$£ ^µuς¶'u¦ºŠ°ðµ°Zìûu¾s”v›Zd¥:Ғ–×Ý [7], A close relative of the rice weevil,[6] the maize weevil has a length of 2.3 mm to 4.9 mm. The complete development time for the life cycle of this species averages 36 days. Infested grains contain holes through which adults have emerged. [7] Ragged holes in individual grains, similar to damage caused by the rice weevil and granary weevil, may indicate infestation. [2] It is able to fly.

The maize weevil also infests other types of stored, processed cereal products such as pasta, cassava,[5] and various coarse, milled grains. Contribution to the morphology and ecology of Sitophilus zeamais Motsch. [7], The maize weevil commonly attacks standing crops, in particular, maize before harvest, and is also commonly associated with rice. An additional aedeagal character for distinguishing Sitophilus zeamais Motsch. The maize weevil (Sitophilus zeamais), known in the United States as the greater rice weevil,[1][2] is a species of beetle in the family Curculionidae. New characters to distinguish larvae and adults of the two sibling species: Sitophilus oryzae(L.) and S. zeamais Mots. Annales de la Societe, Meagher, R.L., Reed, C., Mills, R.B. It infests raw or processed cereals such as wheat, oats, barley, sorghum, rye and buckwheat. A similar pattern was observed by Guzzo et al. 1971. 2011411056) (2018) Uji preferensi hama gudang Sitophilus zeamais Motsch (Coleoptera: Curculionidae) pada berbagai jenis … Syria, Turkey, United States, USSR, Sub Saharan Africa and Yugoslavia. [8] This small, brown weevil has four reddish-brown spots on the wing covers (elytra). However, the only reliable features to distinguish adults of both species are on the genitalia (see table below). Journal of Stored Products Research, 38(3): 259–266. & N;Á¶iYˆ)DåD5«– As S. zeamais larvae feed on the interior of individual grains, often leaving only the hulls, a flour-like grain dust, mixed with frass is evident. Salomo Erwinson Sinaga, (NIM. A single female may lay 300 to 400 eggs during her lifetime. (2002) in a choice experiment with hybrid maize varieties. The impact of grain quantity on the biology of Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae): oviposition, distribution of eggs, adult emergence, body weight and sex ratio. [7], Early detection of infestation is difficult. Population simulation model of Sitophilus zeamais (Coleoptera: Curculionidae) in grains stores in West Africa. Meikle, W.G., Holst, N., Markham, R.H. 1999. Nardon, C, Nardon, P. 2002. Males are then attracted to this pheromone. 1973.

[2] Breeding conditions require temperatures between 15 and 34 °C and[vague]40% relative humidity. [6] Sitophilus zeamais appears similar to the rice weevil (Sitophilus oryzae), but has more clearly marked spots on the wing covers, and is usually somewhat larger.

Development of Sitophilus zeamais and Tribolium castaneum in whole, cracked, and ground pearl millet. in Yugoslavia. Although the maize weevil cannot readily breed in finely processed grains, it can easily breed in products such as macaroni and noodles, and milled cereals that have been exposed to excessive moisture. It has a long, thin snout, and elbowed antennae. The work described here seeks to establish whether changes in VGSC of S.zeamais can explain pyrethroid resistance. Cateto and Colorado showed high attractiveness to the adults of S. zeamais. Mason, L.J.
