Pre-Pupae and Pupae of Anticarsia gemmatalis as Suitable Alternative Hosts for Tetrastichus howardi Mass Rearing

Agronomy
Optimizing mass-rearing systems using alternative hosts is essential for successful biological control programs. This study evaluated the effect of foundress density on the biological parameters of Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae ...

Research notes: Velvetbean caterpillar resistance in soybean selections from crosses involving Mexican bean beetle resistant plants

, 1978
Segregating populations arising from crosses involving two sources of Mexican bean beetle (Epilachna varivestis Mulsant) resistance were screened and selected for resistance to velvetbean caterpillar (Anticarsia gemmatalis Hubner) in Guaiba, Rio Grande ...

Exposure to chlorantraniliprole reduces locomotion, respiration, and causes histological changes in the midgut of velvetbean caterpillar Anticarsia gemmatalis (Lepidoptera: Noctuidae)

, 2021
The anthranilic diamide, chlorantraniliprole is a systemic insecticide affecting ryanodine receptors. This insecticide is used to control caterpillars in soybean crops because it has low toxicity to non-target organisms.

A midlatitude survival model of anticarsia gemmatalis (Lepidoptera: Noctuidae)

, 1990
Midlatitude survival of Anticarsia gemmatalis Hübner, the velvetbean caterpillar, is related to cooling degree-days (°C-days \u3c 10.9°C). Model construction required a cooling degree-day algorithm and spatial distributional-data of velvetbean ...
