Preference Tests

AbstractThis report shows: (1) by starvation tests on representative economic plants that none of them is a suitable host for C. lunula, (2) by feeding tests on plants in the Scrophulariaceae that only plants in the tribe Antirrhineae are potential hosts of the larvae, (3) by feeding tests with plant extracts that plants in the tribe Antirrhineae contain an unidentified feeding stimulant, (4) by preference tests with adults and larvae that, although the moths can be raised with difficulty in the laboratory on snapdragon and other ornamentals in the susceptible tribe, they are unlikely to attack these plants in nature.

Saccharine sorghum has been analyzed as a supplementary prime matter for ethanol production, especially during the sugarcane off-season period. However, it has proven to be highly susceptible to insect attacks during the cultivation cycle. The fall armyworm should be emphasized due to its voracity and high damage capacity enhanced by feeding-caused decrease in photosynthetic area. Current analysis studies the biology and determines the nutritional indexes of Spodoptera frugiperda in saccharine sorghum. Cultivars of saccharine sorghum BRS 506, BRS 509 and BRS 511were evaluated. Duration and survival of the egg, caterpillar, pre-pupal and pupal phases were determined, coupled to weight of pupae and caterpillar, life span, fecundity and pre-egg laying period. Although S. frugiperda completed its life cycle on cultivars BRS 506 and BRS 511, egg-laying and egg feasibility rates were low, whereas insects did not lay eggs on cultivar BRS 509. There was no significant difference in feeding intake by S. frugiperda among these three sorghum cultivars. Results suggest that saccharine sorghum is not a suitable host for S. frugiperda. Biological data reveal that the three saccharine sorghum cultivars are recommended for the grain production system since the number of specimens of the next generation is low or null.
