Weight loss caused by development of Sitophilus oryzae (L.) and Sitotroga cerealella (Oliv.) These population parameters showed that N. lugens can successfully survive and reproduce on both O. rufipogon and TN1. Set alert. The snout is long (1 mm), almost 1/3 of the total length. Seven constituents of the oil were tested for contact and fumigant activity against adults of Callosobruchus chinensis (L.) and Sitophilus oryzae (L.). Bangladesh Journal of Zoology, 18 :67-74. Sitophilus weevils, including Sitophilus oryzae (rice wee-vil), S. zeamais (maize weevil), and S. granarius (granary weevil) (Coleoptera: Curculionidae), are well-known stored-grain insect pests in Turkey and many other coun-tries in the world (Bağcı et al. Analysis by gas chromatography–mass spectrometry led to the identification of 20 volatiles from the steam distilled oil of the leaves from Chamaecyparis obtusa Siebold et Zuccarni. Bulletin of Agricultural Congress Belge, 44 : 1001-1046. But the ease with which the life cycle is completed also depends on the type / variety of rice on which the insect is thriving. In contrast, essential oils from Callicarpa macrophylla Vahl and Zanthoxylum alatum Roxburgh increased the insect population 1.5 and 2 times more than controls in 90 d, respectively; these oils showed significant growth promotion. Seven constituents of the oil were tested for contact and fumigant activity against adults of Callosobruchus chinensis (L.) and Sitophilus oryzae (L.). It has been seen that the life cycle of insect depends upon many factors such as ambient temperature, humidity, water content of the grain etc. Biology of rice weevil, Sitophilus oryzae (L.) (Coleoptera : Curculionidae) in stored wheat Triticum vulgare and its control. Journal of Applied Science And Research, 2014, 2 (6): Study on both the life cycle and morphometrics of, Somnath Das Choudhury*, Kaushik Chakraborty. 交尾後のメス成虫は, ハチ成虫を除去した巣ではおもにハチの繭上にまたは数卵ずつ産卵した. Research Institute for Agriculture. Thesis, University of Agricultural Sciences, Dharwad. The quantity of food ingested and assimilated by S. Life tables of the planthopper Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) on two wild rice species, Oryza officinalis Wall, ex Watt. M. Sc. Of the 112 wild rices evaluated, 82 accessions were resistant to the whitebacked planthopper Sogatella furcifera (Horváth). digital probe thermometer (HTC DT-1) and accordingly recorded. 6 days after emergence and subsequently mating occurs. Sitophilus Oryzae is also called as Rice weevils. It has been seen that the life cycle of insect depends upon many factors such as ambient temperature, humidity, water content of the grain etc. VføädñõúÈê0L$¸¡ÚQ9L¿½ºÌªøPý#>.fåü5Õá|'TT~9>:YLïÎ¯¨~\/«úög>59)÷u9Üæ÷ÓJÈd\W³ßDÙft¨./'õbüîG±HãÄGm½s,%&óÁ|5 Ï£ÉrU>Kè²Ýí±_J¯¡ ÑqEïÀô]ý°ºv°þOQFÒö6ÆC0´|ð/Ç- Cell Systems. Der Reiskäfer oder Reis-Kornkäfer (Sitophilus oryzae) ist ein Käfer aus der Unterfamilie der Dryophthorinae der Rüsselkäfer. Lefevre, P. C., 1953, Etude de Calandra oryzae (L.) sur sorgho (Sorghum vulgare Bert). ambient conditions. Female moths laid a mean of 133.9 eggs during their mean lifetime of 10.7 days. Sitophilus oryzae" Integrated Taxonomic Information System. Three groups of active materials were distinguished: (1) The compounds terpinen 4-ol, 1,8-cineole, and the essential oils of three-lobed sage, sage, bay laurel, rosemary, and lavender were most active againstR. Responses varied with compound and dose rather than increasing exposure time beyond 1 or 2 days. S. oryzae merupakan hama primer yaitu dapat menyerang suatu bahan tanpa ada pertolongan hama lain. Sitophilus is naturally infected with the bacterial endosymbiont Sodalis pierantonius. 6) The average duration of the period performed in cocoon was 12, 12, 187 days for the first, second and the third generation, respectively. Curculionidae). When first-instar larvae were released 10 cm from the base of the nest pedicel, 55% of them arrived in the nest with adult wasps. At 0.05 mg/cm2, moderate activity was achieved with bornyl acetate (56% mortality), α-phellandrene (75%) and terpinolene (55%). 室内実験によって, セグロアシナガバチ Polistes jokahamae の巣に寄生するウスムラサキシマメイガ Hypsopygia postflava の交尾習性と産卵特性, 幼虫の寄主利用の行動を明らかにした. Access scientific knowledge from anywhere. Barbhuiya, M. H., 2002, Biology of rice weevil, Sitophilus oryzae (L.) (Coleoptera : Research Institute for prothorax is strongly pitted with round or irregularly shaped pits. Against S. oryzae adults, at 0.26 mg/cm2, terpinolene caused 93% mortality 2 days after treatment, whereas 80% mortality 4 days after treatment was observed with bornyl acetate and α-phellandrene. Longevity of adult female with food ranged from 85 to109 days. Le charançon du blé, contrairement à celui du riz, ne peut pas voler. 成虫はおもに23:00〜6:00の間に交尾を開始し, 平均交尾継続時間は80.4分であった. Average larval and pupal period were 41.10 days and 10.70 days. Okuni, T., 1924, Insect pests of stored grains in Formosa Part I. and Oryza rufipogon Griff., and on 'Taichung Native 1' (O. sativa indica TN1) were studied at 27 degrees C in the laboratory. observed under laboratory condition covering thr, egg to adult ranges 35-49 days with mean of 41.2 ±, ________________________________________________________________________________. The larvae after full grown pupated inside the rice grain. Agriculture, Formosa, 6 : 1-16. Sitophilus oryzae is a major stored grain pest infesting many grains in storage but rice is its main target of attack. When adult wasps were present on the nest, wasp attacks prevented female moths from approaching the nest, and so they laid eggs singly or in clumps of several tens around the base of the nest pedicel. Etude de Calandra oryzae (L.) sur sorgho (Sorghum vulgare Bert). Biology of rice weevil, Sitophilus oryzae Linnaeus. On hatching the larvae of rice weevil were allowed to feed individuall, specimen tube of 7.5 cm x 2.5 cm size having 5 gram rice grains. Die Art ist ein Vorratsschädling und kann erhebliche Schäden in Nahrungsmittellagern anrichten. Insect and Mite Pests of Durum Wheat. Total larval period lasted for 22-29 days. Bengal, India where no such experiment was carried earlier. This is a representation of a part of a project paper of M.Sc (Zoology) of the first author. About this page.
