Abstract
In laboratory studies in Louisiana on the suitability of rice, sorghum and vasey grass (Paspalum urvillei) as food-plants for the rice pest Oebalus pugnax (F.) at 4 temperatures, there were no significant differences in the weights of 10-day-old nymphs reared on the 3 hosts at 21, 24 and 27°C, but at 30°C the weights of nymphs reared on sorghum were significantly higher than on the other 2 plants. Weights of 15-day-old nymphs followed the same pattern, but there were no significant differences between the weights of insects reared on rice or sorghum at 30°C. At 24 and 30°C, weights of adults were significantly different (rice more than sorghum more than vasey grass), but at 21 and 27°C weights of adults from rice and sorghum were similar. Nymphal survival was significantly higher on rice and sorghum than on vasey grass at each temperature except 21°C, where there was no difference for sorghum and vasey grass. At 21 and 27°C, development time from egg to adult was significantly shorter on sorghum than on rice or vasey grass. Development time at 30°C averaged 22.9 days on rice, 20.7 days on sorghum and 22.3 days on vasey grass
