Grewal and Atwal (1967) concluded that 25 –, wings was fringed with hairs, which was shar, separated so that abdomen is partially visi, shape of their abdomen distinguished male and female. Bangladesh Bureau of Statistics. The total life cycle was completed in 116.92±8.87 and 119.95±8.67 days in males and females, respectively. From another point of view, the new unit had many advantages than the classical one, such as; a-easier handling with the wheat grains used for mass-rearing and Sitotroga eggs added to these grains, b-durability of the new unit than the old one making it less expensive ., c-easier to be manufactured from different metals. The differences in tillage conditions were non-significant with respect to pink stem borer incidence except in the months of late December to early January. Extensive online help - available wherever you are in CAB Direct. Hatching percentages among Sitotroga cerealella eggs were 95.57±0.61 and 96.55±0.62, respectively being nonsignificntly, different. Progeny of both species reached highest numbers on 6-mo infested maize. conglomerate Wolters Kluwer and a minority is owned by the Hungarian Academy 69514 Laudenbach (Photo Credit: John Obermeyer) BIOLOGY AND BEHAVIOR. ... & 8.20±0.20 days for female (Table 2). The highest number of tillers m-2 (357.6) and panicle m-2 (248) were obtained from 25 × 10 cm spacing with 90 kg N ha-1 .The highest harvest index (45.95%) was recorded from 25 × 15 cm spacing with 0 kg N ha-1 . Daily rhythms in parasitization of the Angoumois grain moth Sitotroga cerealella Oliv. Laboratory studies on the bionomics of Angoumois grain Improper storage of paddy after harvesting and processing results in infestation by pests at a large scale. Aproaerema simplixella and T. absoluta accounted for 61.33 ± 5.35% and 51.56 ± 5.22% maximal infestation on groundnuts and tomato leaves, respectively. DNA barcoding is also presented as a valuable tool to complement traditional taxonomy for rapid and accurate identification of these species of agronomic interest. CAB Direct provides session so others can sign in. This is to ensure that we give you the best experience possible. The biology and detection techniques of S. cerealella on rice and maize grains were studied under laboratory conditions at 31±1 °C and 90 ± 5 % relative humidity. (Lepidoptera: Gelechiidae), is a cosmopolitan and most destructive primary insect pest of several stored grains. Department of Entomology, Bangladesh Agricultural University, re 0.10 ± 0.0, 0.4 ± 0.0, 0.6 ± 0.01, 0.8 ±, ngth and width of the pre-pupa and the pupa, nearly 2.3 million people being added each, ce till the next season for their food, feed and, nhusked) at post harvest level. (Lepidoptera: Gelechiidae), was studied on maize varieties, viz. Well-managed hedge orchard will produce quality shots as a source of cutting material, but shoots in this hedge orchard are often attacked by pests which threaten the plants. The biology of Angoumois moth, Sitotroga cerealella (Oliv.) Quick Lime is an Effective Rice Grains Protectant Against the First Instar Larvae of Sitotroga cerealella (oliver) (Lepedoptera: Gelichiidae) in Stored Rice Grains under Laboratory and Store Conditions. The studies showed that pink stem borer is able to complete its life cycle on wheat crop. The ovipositional period, incubation period, larval period, pre-pupal period, and pupal period of Angoumois grain moth were. The biological parameters such as development time, moth emergence and grain damage were correlated with phenolics, flavonoids and tannic acid in these varieties. %PDF-1.5 19(5): 87 -95. In August, the percentage of the folded leaves decreased by 23% while the gall increased by 11.1%. © 2008-2020 ResearchGate GmbH. Gelechiidae, twirler moths) has a wing span of up to 18 mm. Journal of the Asiatic Society of Bangladesh Science, Shahjalal University of Science and Technology. You can now claim your publications on CAB Direct with your ORCID iD! The influence of temperature and humidity on the, Pests of stored products and their control. Basal cold tolerance was relatively compromised (critical thermal minima of 4.52 ± 1.06°C and chill coma recovery time of 5.80 ±1.17 minutes), following 1h at 0°C. In developing countries, cereal grains are the staple food and nearly 70% of the population depends upon agriculture. Results showed significant differences in the performance of treatments (p < 0.001). . If you would like to, you can learn more about the cookies we use. Continuing to use www.cabdirect.org It is called the Angoumois grain moth because long before the early days of the American Republic it had been a pest in the Angoumois Province of France. The results show that differences in climatic conditions influence insect pest species dynamics and response to pesticide treatments. Invasive Gelechiidae pest species, namely Tuta absoluta, Phthorimaea operculella, Aproaerema simplixella, Sitotroga cerealella, and Pectinophora gossypiella are among the major constraints hampering agricultural economy in Kenya. Its wings are elongated and tapered, and have long fringes on the rear edge. Br.) Stored rice insect research, The Rice J. Laboratory studies on the bionomics of Angoumois grain, Douglas, W. A. The newly hatched larvae were transferre, studied and recorded during the period of, period. Trials to determine the efficacy and persistence of five commercially-available synthetic pesticides applied at manufacturer's recommended rates on stored sorghum grain under contrasting climatic conditions were conducted in Mbire (mean temperatures of 32–42 °C and 30–50% rh) and Harare (18–32 °C; 42–75% rh) districts in Zimbabwe. 1967. /Type /Catalog There are over 13,603,000 records available in CAB Direct | Last updated on November 25, 2020. >> Biology: Eggs - 40 to 150 eggs laid on grain surface. (Lepidoptera: Gelechiidae), was studied on maize varieties, viz. The larva then cuts out a circular exit, 2001). The longevity of females was more than that of males. There was no significant relationship between incidence of pink stem borer and weather parameters except relative humidity. The Angoumois grain moth is found worldwide in mild to warm temperate and tropical regions. It was 3.16, 2.58, 1.88 and 1.38 per cent in zero, rotavator, happy seeder and conventional tillage, respectively in 2011-12. Adults of both secondary pest species were allowed to oviposit for 3 wk on intact kernels of 'DeKalb 689', mechanically split kernels, kernels that had been infested for 3 mo by S. cerealella, and kernels that had been infested for 6 mo. moth, Sitotroga cerealella Oliv.
