“…The pequi tree is legally protected in Minas Gerais State (Law 10,883 of 02-20-1992), but their natural habitat has been constantly altered by different human land uses such as cattle-raising pasturelands and agroforestry systems. Thus these trees are commonly found isolated in these structurally simpler habitats (Fernandes et al 2004). However, the pequi phenology change among different habitats (Fagundes et al 2007) and recently, several herbivorous insects have been observed causing damage to the trees located in pasture (M.F.…”

Simplification of natural habitats leads to a modification of the community associated with a host plant. Pequi trees (Caryocar brasiliense) are common to find in central Brazil, especially in the middle of monocultures, such as soy, corn, pasturelands or Eucalyptus plantations. On this scenario we hypothesized that habitat modification differentially affects the diversity of ants and herbivore insects associated with this species. The aim of the work was to test if C. brasiliense trees located in human modified habitats, support a lower species richness and abundance of ants, and a greater species richness and abundance of insect herbivores, compared to preserved cerrado habitats. The study was conducted in a Cerrado area located in Northern Minas Gerais State, Brazil. Ants and herbivore insects were collected monthly during 2005 using beating technique. The results showed that ant species richness was higher in pequi trees located in preserved Cerrado, followed by trees in pastureland and Eucalyptus plantation, respectively. The ant abundance was lower in the Eucalyptus plantation but no difference in ant abundance was observed between trees in pastureland and the preserved Cerrado. Moreover, herbivore insects exhibited lower number of species and individuals in trees located in the preserved Cerrado than in the pastureland and Eucalyptus plantation. We concluded that habitats simplified by human activities may result in diversity loss and may change species interactions.

Entomofauna Associated with Pequi Tree (Caryocar brasiliense Cambess) in Serra da Bandeira, Barreiras, Bahia. Due to lack of information about the interaction between insects and pequi tree in western Bahia, the objective was to identify the composition of the entomofauna associated with pequi tree in two areas presenting different levels of anthropic disturbance (core and border) in Bandeira Sierra, Barreiras, State of Bahia. Also, to verify if the plant phenology and the climatic factors influence in the presence of the associated insects. In order to do so, 20 pequi trees similar in height (5 to 10 m) and phenology were selected, being 10 pequi trees in the core fragment and the other 10 in the border area. The insects were sampled monthly, from December 2015 to December 2016, using the entomological umbrella and the entomological vacuum cleaner methods. The entomofauna was identified at the taxonomic level of family and the quantity, constancy and percentage of the number of insects were sampled. As complementary, the plant phenophase was observed.For data analysis, the activity indexes, Fournier intensity, frequency and duration for phenology were used. For entomofauna, the correlation between phenophases and insects was verified, as well as the correlation between climatic factors and insects. In this study, 1860 insects were collected, being 785 individuals found in the core area and 1075 in the border area. When it comes to richness, in the core area, 22 families were collected, while the border area obtained 23 families. As for phenology, C. brasiliense presented similar patterns in vegetative phenophases in the two study areas, while distinguishing their characteristics in reproductive phenophases.Most of the insect families showed weak negative correlation with the C. brasiliense phenophases. It stands out the foliar fall phenophase and fruiting that presented strong positive correlation with some families. Therefore, the most representative insect family was Formicidae, whereas taxa such as Alleculidae, Erotylidae, Meloidae, Muscidae, Cercopidae, Pyrrhocoridae, Proscopiidae, Romaleidae, Stenopelmatidae and Tettigoniidae were not predominant. Although it is a single species (C. brasiliense), there were differences in the composition of the associated entomofauna between the core and border area, resulting in greater quantity and richness in the latter. As for the phenological aspects (flowering and fruiting), there were also divergences between the core and border area, which may be related to climatic and/or anthropogenic factors. Overall, the entomofauna presented a higher correlation with the C. brasiliense phenophases than with the abiotic factors in Bandeira Sierra. a família de insetos mais representativa foi Formicidae, ao passo que táxons como Alleculidae, Erotylidae, Meloidae, Muscidae, Cercopidae, Pyrrhocoridae, Proscopiidae, Romaleidae, Stenopelmatidae e Tettigoniidae não predominaram. Mesmo sendo uma única espécie (C. brasiliense), ocorreram diferenças na composição da entomofauna associada...
