Control of Rice Water Weevil with Fipronil, 1995 [PDF]
Abstract Various formulations and application times of fipronil were compared with Furadan 3G and an untreated check for control of RWW. The experimental design was a RCB with 4 replications. Plot size was 9 rows (7 inch row spacing) X 25 ft with a 2 ft alley between plots.

Endosymbiosis allows Sitophilus oryzae to persist in dry conditions
Insects frequently associate with intracellular microbial symbionts (endosymbionts) that enhance their ability to cope with challenging environmental conditions. Endosymbioses with cuticle-enhancing microbes have been reported in several beetle families.
