Abstract

First report of Chrysodeixis includens (Walker, [1858]) (Lepidotera: Noctuidae) injurious to pineapple (Ananas comosus L.) (Bromeliaceae) in Brazil.

Abstract

The presence of larvae of Chrysodeixis sp. was observed in pineapple cv. Smooth Cayenne plants during surveys conducted at the Experimental Station of the Agronomic Institute of Paraná, Brazil, in the municipality of Santa Helena, in March 2015. The infested plants were 20 months old (in full bloom), growing in an area of approximately 0.6 ha adjacent to a final-stage soyabean crop. The larvae had a light green colour with longitudinal white stripes interspersed with black dots along the body. Specimens of fourth and fifth instar larvae were collected from the plants and sent to the laboratory where they were kept under ambient conditions and fed soyabean leaves until the emergence of the adults for confirmation of their identity. The pest was identified as C. includens based on the morphological characteristics of the adults. This is thought to be the frist report of the occurrence of C. includens on pineapples in Brazil.
