Butterfly Pests (Lepidoptera) Occurring on Vegetable Crops in Poland
Abstract
There are over 2,240 butterfly species of Lepidoptera belonging to 17 families recorded in Poland. Of those, 63 phytophagous species have been noted in vegetable agrocenoses at a level of pest status. They constitute 18% of all harmful entomofauna found on vegetable crops. The species described in this paper are common on all vegetable crops growing in Poland, and all parts of plants. The most abundant pests found on aerial parts of crops include the silver Y moth (Autographa gamma), which causes damage to 20 species of vegetables, and species belonging to the genera Mamestra, Lacanobia and Anarta, which feed on more than 10 vegetable species. Of the polyphagous leaf roller moths (Tortricidae), the most numerous are the species belonging to the genus Cnephasia. Periodically, they pose a significant threat, among others for beetroot, pea, cucumber, and lettuce. The diamondback moth (Plutella xylostella) and the cabbage butterfly (Pieris rapae) are dominant butterfly pests on brassica vegetables. A component of harmful entomofauna on onion crops is leek moth (Acrolepiopsis assectella), a species permanently dominant on onion vegetables in Poland since 1930s. The species of the family Depressariidae cause the greatest damage on the generative organs of seed crops, mainly of dill, carrot and parsley. Underground parts of vegetable crops are damaged by cut-worms (Noctuidae), which belong to the group of soil-borne pests. Among more than 60 species belonging to this family, nine cause the greatest damage to vegetable crops. The turnip moth (Agrotis segetum), as a dominant species in recent years, accounted for about 80% of cutworms damaging vegetable crops, and prefers onion, leek, carrot, parsley, celery and corn. Although the European corn borer (Ostrinia nubilalis) is considered a polyphagous species, it forms the most abundant populations on maize out of all other crops.
