Relative Yield Loss From Stem Borers (Lepidoptera: Crambidae) and Rice Water Weevil (Coleoptera: Curculionidae) in Rice

Journal of Economic Entomology, 2021
The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most important economic pest of rice in the United States with the ability to substantially reduce rice yields.

Differential response to the South American rice water weevil (Coleoptera: Curculionidae) damage of rice cultivars with contrasting levels of resistance: implications for field management.

Pest Management Science, 2022
BACKGROUND Oryzophagus oryzae (Costa Lima) (Coleoptera: Curculionidae) is a major pest of flooded rice paddies throughout South America, and species with very similar life histories are present in many rice-producing regions of the world (collectively ...

Tolerance to rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), infestations among hybrid and inbred rice cultivars in the Southern U.S.

, 2021
The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most destructive insect pest of rice in the U.S. This insect poses a global threat to rice production, having invaded rice-producing regions of Asia and Europe. Tolerance is a type of plant

Assessment of tolerance and resistance of inbred rice cultivars to combined infestations of rice water weevil and stemborers

, 2021
Plants possess defense‐related traits that both reduce injury from herbivores (resistance) and the amount of yield loss per unit injury (tolerance). Plant resistance and tolerance can be utilized in pest management programs.

Influence of Soil Moisture Zones on Rice Water Weevil (Coleoptera: Curculionidae) Populations in Furrow Irrigated Rice

Environmental Entomology, 2021
Water conservation is an important factor for production of rice in the United States because of declining aquifer levels, but little research has been done to evaluate insect management in rice systems integrating water conservation practices.

Rice Water Weevil, 1980

Insecticide and Acaricide Tests, 1981
Abstract Rice was planted in Crowley silt loam May 9 and flodded June 13. Three tests were each arranged in a randomized complete block design with 3 (Test 2) or 4 (Test 1 and 3) replications. Granular treatments (Test 1) were applied with a hand shaker just prior to flooding on June 13 to plots 3.5 x 15 ft.

Rice Water Weevil Control, 1981

Insecticide and Acaricide Tests, 1982
Abstract Rice was planted Apr 28 in Crowley silt loam at the Rice Research and Extension Center, Stuttgart, AR. Both tests were arranged in a randomized complete block design with 4 (Test I) or 3 (Test II) replications. All plots were sampled for root-feeding larvae by taking 5 soil cores (9 cm dia x 7 cm deep) from the drill rows of ...

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, 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 ...
