“…The findings of the present study support the hypothesis that patch characteristics determine the distribution of A. sylvia larvae because larvae occurred in higher densities in homogeneous patches of V. angustifolium located away from forest edges. These results are in agreement with studies of edge effects and the presence of nonhost plants on adult dispersal in other chrysomelid species (Lawrence & Bach, ; Linzmeier & Ribeiro‐Costa, ). The unaggregated distribution hypothesis was rejected because larval densities and defoliation exhibited aggregated distributions.…”

1 The role of endogenous (i.e. limited dispersal, intraspecific competition, aggregation) and exogenous (i.e. resource patchiness, heterogeneous landscapes, spatially structured habitat) factors on the spatial distribution of herbivores can be inferred from theoretical models in intensively managed or heterogeneous landscapes but not in extensively managed crops. 2 In the present study, we examined aggregation patterns and the influence of environmental and spatial factors on the distribution of Altica sylvia Malloch larvae within extensively managed blueberry fields to determine how exogenous and endogenous factors affect this defoliator. 3 Altica sylvia larvae and defoliation exhibited clumped within-field distributions.A lack of correspondence between larval density and defoliation indicated that oviposition habitat selection is occasionally suboptimal in this species. 4 Clumped distribution patterns were not explained by endogenous factors or associations with spatially structured variables. Conversely, exogenous factors acting at the patch scale affected distribution patterns because larvae were less abundant in patches located close to forest edges, as well as in patches where weeds or a nonhost blueberry plant occurred. 5 As a result of exogenously-produced variability in A. sylvia spatial distribution, we suggest that focused sampling methods be used to monitor this herbivore. We emphasize the need for similar assessments for herbivores that forage in extensively managed crops or somewhat heterogeneous monocultures.

“…It has been determined that habitat heterogeneity and diverse characteristics of conservation areas can promote high beta diversity or low similarity between sites, regardless of the distance (Linzmeier and Ribeiro-Costa 2009). This was observed with the lowest site of Cerro El Diente and the other three sites within the same locality, as they formed different faunistic groups, although they are geographically close to each other.…”

The study of biodiversity of Chrysomelidae in Mexico and its variation within ecological gradients has increased recently, although important areas in the country remain to be explored. We conducted a faunistic inventory and analyzed the elevational and temporal variation of leaf beetle communities in the Sierra de San Carlos, in the state of Tamaulipas, in northeastern Mexico. This is an area with high to extreme priority for conservation, and due to its insular geographical position and to the vegetational communities present, it must be considered as a sky island. We selected seven sample sites distributed in different elevations within three localities, and comprising different vegetational communities. At each site, we randomly delimited 12 sample plots of 400 m2 where sampling was conducted by entomological sweep netting and collecting directly by hand. Sampling was conducted monthly at each plot, for a total of 1,008 samples between February 2013 and January 2014. By the end of the study, we had obtained a total of 3,081 specimens belonging to six subfamilies, 65 genera, and 113 species, with Trichaltica scabricula (Crotch, 1873) being recorded for first time in Mexico. Species richness was less than the values observed at other studies conducted in the same region, which is attributed to differences in the number of plant species and to the insular location of Sierra de San Carlos; however, the higher diversity values suggest a higher quality of natural resources and vegetational communities. No consistent pattern of leaf beetle communities was correlated with elevation, although higher values of species richness and diversity were obtained at the highest elevation site. The seasonal gradient showed that the rainy season is most favorable for leaf beetle communities. We found that species composition was different between sites and months, and also that there exists a significant association between the abundance obtained at each site and particular months. These results highlight the importance of different microhabitats for species distribution, and suggest that each species of Chrysomelidae has a differential response to environmental factors that vary within the elevational gradient and according to seasons. Also, we confirm and emphasize the important status of Sierra de San Carlos as a key natural area for biological conservation.

“…Assessing the seasonality of these species, the first two were shown to have a pattern similar to that found in the present study. The Trichaltica species, T. elegantula Baly, 1876, occurred only from September to November and was recorded feeding on flowers of Allophylus edulis (St. Hil) Radlk (Sapindaceae) (Linzmeier & Ribeiro-Costa 2009). According to Bechyné (1997), species of this genus are found on flowers, sometimes damaging them.…”

Abstract:The aim of this paper was to describe the seasonal patterns of Chrysomelidae and of its most abundant species at eight sites in different geomorphological and floristic regions in the state of Paraná, southern Brazil. Samples with Malaise traps, from August 1986 to July 1988 were performed. The Chrysomelidae showed seasonal patterns with the highest abundance in the spring and/or summer at all sites, but with variations in the months of highest captures. Photoperiod was the variable that most influenced the seasonality of Chrysomelidae, and along with temperature and relative humidity, determined most of the seasonal patterns of the family at the different sites. Some dominant species of Chrysomelidae showed different seasonal pattern compared to the family level. A better knowledge of the seasonal distribution patterns of these species will only be possible when their life history, such as host plants and behavior, was better understood. Resumo: O objetivo deste estudo foi descrever os padrões de sazonalidade de Chrysomelidae e de suas espécies dominantes, capturadas em oito locais de diferentes regiões geomorfológicas e florísticas do estado do Paraná, sul do Brasil. As coletas foram realizadas com armadilha Malaise de agosto/1986 a julho/1988. Chrysomelidae apresentou padrão sazonal com picos de abundância na primavera e/ou verão em todos os locais, mas com variações quanto aos meses de maior captura. O fotoperíodo foi a variável com maior influência na sazonalidade de Chrysomelidae e juntamente com a temperatura e umidade relativa, determinaram a maioria dos padrões sazonais da família nos diferentes locais. Algumas das espécies dominantes de Chrysomelidae apresentaram padrão sazonal distinto do observado para a família. O entendimento dos padrões de distribuição das espécies de Chrysomelidae somente será possível quando informações sobre a história de vida, como plantas hospedeiras e comportamento, forem melhor esclarecidas. Palavras-chave: abundância, Alticini, insetos herbívoros, padrão de distribuição, sazonalidade.
