IMPACT OF MANGO MANILA MANAGEMENT SYSTEMS ON ARTHROPODS IN FOLIAGE AND WEEDS

Abstract

In recent years, cultivation of mango Manila in the State of Veracruz, Mexico, has had a tendency of increased technification and continuous substitution by sugarcane. All this is causing a negative impact on the environment and biodiversity. Thus, the impact of mango Manila management systems on arthropods in foliage and weeds was evaluated. Arthropods associated with foliage and weeds were sampled during different seasons of the year on each management system: technified, transitional, minimum traditional, and substituted by sugarcane. Abundance, diversity and richness by substrate, system and season were calculated. Comparisons between the minimum traditional system and each one of the others were made with Student´s t-test (P ≤ 0.05). The system substituted by sugarcane had a negative impact on abundance, diversity and richness of arthropods in weeds and foliage during the dry season. The effect of management systems were significantly different after pooling seasons, with greater values during the rainy season, and similar in the dry and winter seasons. System substituted by sugarcane showed a negative impact on diversity during the dry and rainy seasons.
