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, 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)

Impact of planting date on rice water weevil (Coleoptera: Curculionidae) and stemborer (Lepidoptera: Crambidae) infestations in drill-seeded rice.

Environmental Entomology
The rice water weevil, Lissorhoptrus oryzophilus (Kuschel), is the most widely distributed and destructive early-season pest of rice in the United States. Injury caused by feeding of weevil larvae on rice roots results in significant yield losses.

Ligand Binding Characteristics and Functional Analysis of Odorant-Binding Proteins in Rice Water Weevil Lissorhoptrus oryzophilus (Coleoptera: Curculionidae).

Journal of Agricultural and Food Chemistry
LoryOBP29 and LoryOBP40 were cloned from Lissorhoptrus oryzophilus. Tissue expression analysis showed that both LoryOBP29 and LoryOBP40 were highly expressed in antennae and heads.

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.

Impacts of Seeding Rate on Interactions Between Rice and Rice Water Weevils

Journal of Economic Entomology, 2009
The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most widely distributed and destructive early season insect pest of rice, Oryza sativa L., in the United States. Economic losses result primarily from feeding by the larval stage of this insect on the roots of flooded rice plants.

Binding Characteristics and Functional Analysis of Odorant-Binding Protein 17 in the Rice Water Weevil (Lissorhoptrus oryzophilus) with Host Volatiles.

Journal of Agricultural and Food Chemistry
Odorant binding proteins (OBPs) are essential for insect olfaction. Lissorhoptrus oryzophilus (Coleoptera: Curculionidae), known as the rice water weevil, is a destructive pest of rice.

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
