Rice Water Weevil Control, 1982

Insecticide and Acaricide Tests, 1984
Abstract Insecticides were evaluated in five experiments at the Rice Res. and Ext. Cent, in Stuttgart, Ariz. Rice was planted in Crowley silt loam: ‘Starbonnet’ on 11 May for tests I to IV and ‘Lebonnet’ on 8 June for test V. Each test was arranged in a randomized complete block design with four (Tests I and II) or three (Tests III to V)

Growth and Yield Response of Rice to Rice Water Weevil Injury

Environmental Entomology, 1997
Analysis of larval and pupal age-structured data indicates that the soil core sampler–soil separation method underestimates the abundance of early instar rice water weevil, Lissorhoptrus oryzophilus Kuschel. The estimates for bias were used to derive seasonal larval age-structured population estimates for 4 yr of field data from 2 experiments ...

Molecular marker-assisted detection of rice weevil in stored rice

International Journal of Pest Management, 2006
Abstract Stored cereal crops form the major component of the world's food supply. It is well known that post-harvest crop losses, due to insects and microbes, cause significant economic waste in both developed and developing countries. In general, the environment in storage facilities is prone to rapid pest development, leading to significant grain ...

Rice Water Weevil Control, 1986

Insecticide and Acaricide Tests, 1987
Abstract Rice was planted 22 May on loessial silt loam soil at the Macon Ridge Branch of the Northeast Research Station. The experimental design was a randomized complete block design with 4 replications. All plots were sampled for root feeding larvae by taking 3 soil cores (9 cm dia × 10 cm deep) from drills rows, once a week, for 4 ...

Rice Stink Bug and Rice Water Weevil Control, 1982

Insecticide and Acaricide Tests, 1984
Abstract Insecticides were tested on heading rice at the Rice Res. and Ext. Cent, at Stuttgart, Arz., for control of rice stink bug and rice water weevil adults. Both insect species were exposed to insecticides by confining them together on rice panicles with organdy sleeve cages (30 cm diam. by 55 cm long). First, cages were placed over

Control of Rice Water Weevil with Nematodes, 1990

Insecticide and Acaricide Tests, 1992
Abstract Experiments, designed as randomized complete blocks, were conducted at the Texas A&M University Agricultural Research and Extension Center at Beaumont and its satellite station at Eagle Lake. Each of 2 experiments at Beaumont and a single experiment at Eagle Lake consisted of 5 and 8 treatments, respectively, all with 4 ...

Influence of Rice Variety on Oviposition and Development of the Rice Weevil, Sitophilus oryzae, and the Maize Weevil, S. zeamais

Annals of the Entomological Society of America, 1968
Subsequent to the field trials of Doggett (1957), which confirmed the existence of varieties of sorghum resistant to the rice weevil, Sitophilus oryzae (L.), other workers have indicated the effects of this and other grain species on the biology of this insect.

Activity of Safrotin Against the Rice Weevil, 1982

Insecticide and Acaricide Tests, 1981
Abstract Two dilution rates of Safrotin 4EC were used for testing purposes, 0.5 and 1.0. Masonite panels cut to 1 ft2 (929 cm2) were treated and used as exposure surfaces. A spray apparatus equipped with a conveyor belt was used to apply the pesticide to the panels. A stainless steel nozzle, Spraying Systems Tee-jet 8001, was used during
