Gravimetric Method for the Measurement of Sugar Consumption by Adult Velvetbean Caterpillar (Lepidoptera: Noctuidae)

Meagher & Landolt: Floral Lures Attractive To Velvetbean Caterpillar 73 BINARY FLORAL LURE ATTRACTIVE TO VELVETBEAN CATERPILLAR ADULTS (LEPIDOPTERA: NOCTUIDAE)

Evaluation of combinations of flower odor compounds in northern Florida revealed that linalool was synergistic in attractiveness with phenylacetaldehyde (PAA) to the migratory moth velvetbean caterpillar ( Anticarsia gemmatalis Hübner). This noctuid was the most common species collected from traps with a binary lure composed of PAA and linalool, with over 900 males and females collected in Sep ...

Intraspecific variation and population structure of the Velvetbean Caterpillar, Anticarsia gemmatalis Hübner, 1818 (Insecta: Lepidoptera: Noctuidae)

The velvetbean caterpillar (VBC), Anticarsia gemmatalis Hübner, 1818 (Insecta: Lepidoptera: Noctuidae), is one of the most important New World soybean agro-ecosystems pests, occurring from 40° N in the USA to 39° S in Argentina. Information on the migration patterns of the VBC moth may be important for managing the resistance of VBC populations to insecticides or plants carrying the Bacillus th...

Fitness cost of resistance to Bacillus thuringiensis in velvetbean caterpillar Anticarsia gemmatalis Hübner (Lepidoptera, Noctuidae)

Fitness cost of resistance to Bacillus thuringiensis in velvetbean caterpillar Anticarsia gemmatalis Hübner (Lepidoptera, Noctuidae). Selection pressure to obtain resistant genotypes can result in fitness cost. In this study, we report the effects of the selection pressure of a commercial formulation of Bacillus thuringiensis on biological aspects of a Dipel-resistant strain of velvetbean cater...

Caterpillar (lepidoptera: Noctuidae) Feeding on Pasture Grasses in Central Florida

Stargrasses ( Cynodon nlemfuensis Vanderyst var. nlemfuensis ) and bermudagrasses ( C. dactylon (L.) Persoon) are important warm-season forage grasses, with several cultivars developed for conditions found in central and southern Florida. Major insect pests of these grasses include grass loopers ( Mocis spp.) and fall armyworm ( Spodoptera frugiperda (J. E. Smith)), which annually may impose ec...
