Diversity of entomofauna associated with different crops plots neighboring in Cesar department, Colombia
Journal Title: REVISTA CHILENA DE ENTOMOLOGÍA - Year 2022, Vol 48, Issue 3
Abstract
Vegetables are staple foods and an important source of nutrients for health. In Colombia, phytosanitary problems limit yields and competitiveness in international markets. With the objective of evaluating the diversity of the associated entomofauna in five adjoining crops such as pumpkin, eggplant and two bean species in the department of Cesar in Colombia. Sampling and collections were carried out fortnightly in the horticultural systems during August to October 2017 in the study area. Schannon and Simpson abundances and diversity indices were analyzed by family and genus. The functional groups (phytophagous and biological controllers) of the genera were also typified. The most abundant orders were Hemiptera, followed by Coleoptera and Hymenoptera. Chili pepper presented greater abundance of insects (P = 0.6275) and greater and equal dominance in family and gender diversity according to the Simpson index (D = 0.34). Cowpea beans presented greater richness and diversity of families according to the Shannon index (H’=2.32) and gender (H’=2.72) respectively, while the family with greater abundance was Cicadellidae in the chili and pink bean crops and squash was the crop with the greatest difference between the sampled and predicted families (Chao1= 21). The most abundant genera were Systena sp. (Chrysomelidae) in pumpkin, Solenopsis sp. (Formicidae) in eggplant, Cicadella sp. (Cicadellidae) in chili and pink bean. The highest percentage of phytophagous was found in squash and the highest percentage of predators in eggplant. The abundance of entomofauna was similar in the different crops evaluated, due to the proximity between them, highlighting the Cicadellidae, Chrysomelidae and Carabidae families.
