Helicoverpa armigera (Huèbner) and H. zea (Boddie) (Lepidoptera: Noctuidae) in corn, soybean and sunflower in Puerto Rico

On-Demand
Student Competition On-Demand
The old-world bollworm Helicoverpa armigera (Lepidoptera - Noctuidae) is a polyphagous pest considered to be one of the most destructive agricultural pests in the world. Since 2013, several studies have reported the occurrence of this pest in South America, causing economic losses in cotton, soybean, corn, and other crops. In 2014, USDA/APHIS confirmed the occurrence of H. armigera in some areas of Puerto Rico. The occurrence and seasonal flight of H. armigera in seed production areas of corn, soybean and sunflower in the southern municipalities of Puerto Rico were evaluated by pheromone trapping and field sampling. The proportion of H. armigera/H. zea in corn, soybean, and sunflower was documented based on genital morphology and molecular analysis. The possible presence of H. zea and H. armigera hybrids within the population is discussed.
