Desenvolvimento pós-embrionária de ascia monuste orseis (lepidoptera: pieridae) alimentadas com espécies de brassicales

Abstract

Kale caterpillar Ascia monuste orseis (Latr., 1819) is considered one of the main defoliating pests in plants of Brassicaceae family. However, considerable losses can occur due to their attack, and there may be degradation of the entire production causing economic losses for producers. The knowledge of varieties that best provide the development of kale caterpillar is important in pest control programs, once the development of research is necessary rearing the species in laboratory. Thus, this research aimed to study the post embrionary development of A. monuste orseis feed with a variety of the Cleomaceae family (‘Mussambê’ Cleome spinosa L.) and three varieties of Brassicacea (common kale B. oleracea var. acephala; ‘tronchuda’ or ‘Portuguesa’ B. oleracea var. tronchuda and mustard Sinapis alba), in order to stock production of kale caterpillar to be used in future control program studies. Four treatments were tested, with twenty repetitions, each, totaling 80 repetitions. The evaluated aspects were the duration of instars and pupal phase, as well the post embrionary development period. The data were compared using Tukey test (5%). The Brassicaea common kale B. oleracea var. acephala; ‘tronchuda’ or ‘Portuguesa’ B. oleracea var. tronchuda and mustard Sinapis alba were the more favourable to post embrionary development of A. monuste orseis, and therefore more recommended for producing kale caterpillar in laboratory, then Cleome spinosa.
