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)

Rice Water Weevil Control, 1985

Insecticide and Acaricide Tests, 1987
Abstract The experiment was conducted at the TAMU Agricultural Research and Extension Center at Beaumont. ; The design was a randomized complete block with 12 treatments and 4 blocks. Each experimental unit was 20 ft × 5 ft and surrounded by a metal barrier to prevent contamination from other units.

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.

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 ...

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.

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 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

Resistance to Aldrin in the Rice Water Weevil in Louisiana

Journal of Economic Entomology, 1967
Laboratory studies conducted during 1965 and 1966 using the topical-application technique demonstrated resistance to aldrin in the rice water weevil, Lissorhoptrus oryzophius Kuschel, in Louisiana. High levels (100- to two-fold) of resistance were found in weevils from Alsatia, Crowley, and Ville Platte.

Control of Rice Water Weevil with Dimilin, 1989

Insecticide and Acaricide Tests, 1990
Abstract The experiment was conducted at the Texas A&M University Agricultural Research and Extension Center at Beaumont. The experimental design was a randomized complete block with 5 treatments and 4 replicates. Each plot was 6 × 13 ft surrounded by a metal barrier to prevent contamination among plots.
