The genome and stage-specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions. [PDF]
Insect Mol BiolComprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

Control of Rice Water Weevil with Fipronil, 1995 [PDF]
Arthropod Management Tests, 1996 Abstract The experiments were conducted at the TAMU Agricultural Research and Extension Center at Beaumont. Experiment I was water-seeded rice with continuous flood. The experiment was designed as a RCB with 9 treatments and 4 replications. Each plot was 15 ft X 8 ft, surrounded by a metal barrier to prevent movement of insecticide.

Rice Water Weevil Control, California, 1990 [PDF]
Arthropod Management Tests, 1994 Abstract Two experiments were conducted to compare control of RWW larvae (Experiment 1) or adults (Experiment 2) among insecticide treatments. Both tests were performed at the California Rice Experiment Station, Biggs, in 1990. Each experiment was a RCBD with 3 replications of 3 insecticide treatments and an untreated control. Treatments
