Abstract:
Population development by the rice weevil, Sitophilus oryzae (L.) and feeding damage caused by the lesser grain borer, Rhyzopertha dominica (F.), were assessed on twelve triticale (X Triticosecale Wittmack) genotypes maintained at 25°C and at 11.7 or 14.2% moisture content. Among genotypes at 14.2% moisture content, total progeny production by the rice weevil ranged from 7.1 (GA82014) to 8.8 (87AB13541) weevils per female-day; mean time to adult emergence ranged from 35.5 (GA82014) to 36.9 days (87AB13541 and CT4699); and rate of emergence (a measure of the slope of the cumulative emergence cu

Abstract:
The wheat bug, Aelia germari, feeds on developing wheat kernels, causing a loss in baking quality of the harvested wheat (Triticum aestivum). The possible nutritional changes in the bug-damaged kernels after the harvest were tested in a bioassay using the rice weevil Sitophilus oryzae, which feeds on the kernel endosperm. The weevils were reared on baking wheat cultivar 'Manon demias', grown in Algeria, with different levels (0, 4, 8 and 13%) of wheat bug (A. germari) damaged kernels. Rice weevil reared on 4, 8 or 13% damaged wheat had a shorter development time than on wheat with no damage. H

Abstract:
Abstract Plant structural traits can act as barriers for herbivore attachment, feeding, and oviposition. In particular, epicuticular waxes (EWs) on the aerial surfaces of many land plants offer protection from biotic and abiotic stresses. In rice (Oryza sativa L.), mutations that reduce EWs have been previously reported. However, whether such mutations affect rice water weevil (Lissorhoptrus oryzophilus Kuschel) and fall armyworm (Spodoptera frugiperda Smith) performance has not been investigated yet. These pests cause significant economic problems in important rice-producing areas of the Unit

Abstract:
In order to find natural and inexpensive bioinsecticides, the active compound of waste extract from two medicinal plants were analyzed. Ethanolic extracts of Amomum cardamomum and Zingiber zerumbet were evaluated under laboratory conditions for their repellency against rice weevil (Sitophilus oryzae, L.). Four extracts concentration were tested in this research, i.e: 25, 50, 75 and 100%. Efficacy was measured based on the response of rice weevil in preference tests using Y Olfactometer Tube, then the results were converted into the Percentage Repellency (PR) and Preference Index (PI).

Abstract:
Oviposition preference and development of rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae) were observed in three varieties of stored grains i.e. parboiled rice (Oryza sativa), wheat (Triticum aestivum) and pulse (Cicer arietinum). In no choice tests, the mean number of eggs laid were 360.3 ±2.60 in rice, 382 ±2.49 in wheat and 394± 2.06 in pulse. In case of choice tests, the mean number of eggs laid were 13.6±0.4 in rice, 14.2 ±0.37 in wheat and 15.6 ±0.4 in pulse. The differences between the number of eggs laid in rice, wheat and pulse varied significantly in both no-choice and cho

Abstract:
This paper presents the dielectric properties characterization of the rice and rice weevil for microwave heating disinfestation treatment application. Infestations of insects in stored grain have become a major threat to food supply globally. It contributes to damage to the stored grain and had caused economic losses. The current method to control the infestation which is by using chemical fumigation could give harm to human health and cause environmental pollution. The ability of microwave energy to kill the insects using dielectric heating technique has a high potential as an alternative met

Abstract:
The use of entomopathogenic fungi to control agriculturally important pests, both in greenhouses and in the field, has been demonstrated by various authors for a number of years. This has been brought about by the development of resistance in certain pest species to chemical applications and a growing public awareness of the safety implications of residual insecticides. Several entomopathogenic fungi were tested against four insect pests found in the Republic of South Africa (RSA), the greenhouse whitefly, Trialeurodes vaporariorum, the rice weevil, Sitophilus oryzae, the grapevine mealybug, P
