Rice Water Weevil Control, 1984

Insecticide and Acaricide Tests, 1985
Abstract Rice was planted in Crowley silt loam at the Rice Research and Extension Center in Stuttgart, AR; ‘Lebonnet’ was planted on 14 May for the first two tests and ‘Bond’ on 21 Jim for the third. Plots for the first preflood test were 6 ft x 15 ft; all other plots were 5-ft dia and surrounded by aluminum flashing to prevent water ...

Rice Water Weevil Control, 1983

Insecticide and Acaricide Tests, 1984
Abstract Rice was planted in Cowley silt loam at the Rice Res. and Ext. Cent., Stuttgart, AR. Plots for the CN 11-3877 10G preflood test were 5 by 15 ft. All other plots were 5 ft dia cm and enclosed by aluminum flashing to prevent water movement.

The influence of rice plant age on susceptibility to the rice water weevil, Lissorhoptrus oryzophilus

Journal of Applied Entomology, 2013
Plant age- and plant stage-related changes in the resistance of rice, Oryza sativa, to its most important insect pest in the US, the rice water weevil (Lissorhoptrus oryzophilus), were investigated in a series of field and greenhouse choice and no-choice

Integrating flood depth and plant resistance with chlorantraniliprole seed treatments for management of rice water weevil, Lissorhoptrus oryzophilus (Coleoptera: Curculionidae)

Insect Science, 2015
© 2014 Institute of Zoology, Chinese Academy of Sciences. Chlorantraniliprole seed treatments in rice provide effective suppression of rice water weevil populations in the United States; however, heavy reliance on prophylactic insecticide treatments as a

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)

Chemical Control of the Rice Water Weevil

Journal of Economic Entomology, 1961
Small plot tests were conducted during 1959 and 1960 to control the larval stage of the rice water weevil, Lissorhoptrus oryzophilus (Kuschel). Aldrin and heptachlor were equally effective either when applied as a seed treatment or when mixed with fertilizer.

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 ...

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 ...

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 Carbofuran, 1991

Insecticide and Acaricide Tests, 1992
Abstract Carbofuran was evaluated for control of RWW at Stuttgart (Crowley silt loam soil) and Keiser (Sharkey silt clay soil), AR. The experimental design was a randomized complete block with 4 replications. Plot size was 9 rows with 17.8 cm spacing × 4.88 m.
