First record of Teratopactus nodicollis (Coleoptera: Curculionidae) in dry bean (Phaseolus vulgaris)
Neotropical Entomology 41 (3), 252-253
Abstract: Observations on the bioecology and damage of Teratopactus nodicollis Boheman on Phaseolus vulgaris were carried out on field samples by assessing the number of larvae and root damage in 40 ha of a dry bean field from the Federal District, Brazil (16°4'28.41" W; 47°30'21.13" S). Larvae caused the greatest damage at the stage of germination, emergence, and primary leaves, producing 50 % stand reduction. Most larvae pupated in August and September, and adult emergence occurred in middle October. Some larvae were infected with the fungus Metarhizium spp., a biological agent that would be naturally controlling this insect.
