چکیده
The studies on screening of 15 varieties wheat viz., WH 1105, 1124, 1142, 283, 542, 711, 1080, 1025, 157, DBW 17, DPW 62150, HD 2967, PBW 343, C 306 and 147 for ovipositional preference (choice no choice test), adult emergence grain damage (number weight basis both) by S. oryzae were carried out under laboratory conditions during August to October, 2017. Results revealed that the minimum oviposition (166.67 eggs per 250 grains), (66.68 adults) lowest (14.12 5.65% number loss basis, respectively) recorded in variety 306. highly preferred (368.78 (118.33 (25.53 9.84% was 147. It also observed none free from infestation oryzae. However, 1080 157 found moderately suitable. Varieties 542 1025 less least preferred, whereas be most as eggs, adults emerged, (%) maximum followed 62150 343.

Control of rice weevil (Sitophilus oryzae L., Coleoptera: Curculionidae) with various formulations of Metarhizium anisopliae
Formulations of Metarhizium anisopliae conidia with oven ash, chalk powder, charcoal and wheat flour at a ratio of 1:4 (W/W) were prepared. Formulations containing charcoal and oven ash had a conidial viability half-life of 4.1–4.3 months at 2071!C. In comparison, unformulated conidia held under the same conditions had a viability half-life of 0.9 month. Bioassays carried out at 2872!C and 7075...
متن کاملOvarian physiology and age-grading in the rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae)
Physiological and morphological changes in the ovarian system in rice weevils, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), reared on wheat seeds were studied as a function of adult age, mating status, and nutrient availability. X-ray analysis was used to determine time of adult eclosion and the duration of development of pre-emergent weevils within the seeds, a process that lasted almos...

متن کاملInfluence of maternal age on the fitness of progeny in the rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae).
We studied the effects of maternal age on fitness of progeny in the rice weevil, Sitophilus oryzae L. (Coleoptera: Curculionidae). Five-, 20-, and 50-d-old female rice weevils were used to study the effects of maternal age on the lifetime fecundity and longevity of their daughters. In addition, we determined the effects of maternal age on the weight and survivorship of daughters' progeny. Daugh...
متن کاملThermal treatments to increase acoustic detectability of Sitophilus oryzae (Coleoptera: Curculionidae) in stored grain.
Hidden infestations of stored-product insect larvae are detected most rapidly by acoustic techniques when the larvae are highly active. Larval activity is periodic, however, and it tends to decrease after the larvae are disturbed or cooled. Because of the practical need for rapid inspection of grain at commercial elevators, several heat treatments were tested as potential methods of increasing ...
