Urban gardens are a prominent part of agricultural systems, providing food security and access within cities; however, we still lack sufficient knowledge and general principles about how to manage pests in urban agroecosystems in distinct regions. We surveyed natural enemies (ladybeetles and parasitoids) and conducted sentinel pest removal experiments to explore local management factors and landscape characteristics that influence the provisioning of pest control services in California, USA, and Chiapas, Mexico. We worked in 29 gardens across the two locations. In each location, we collected data on garden vegetation, floral availability, ground cover management, and the percentage of natural, urban, and agricultural land cover in the surrounding landscape. We sampled ladybeetles, Chalcidoidea, and Ichneumonoidea parasitoids with sticky traps, and monitored the removal of three different pest species. Ladybeetle abundance did not differ between locations; abundance decreased with garden size and with tree cover and increased with herbaceous richness, floral abundance, and barren land cover. Chalcicoidea and Ichneumonoidea parasitoids were more abundant in Chiapas.

Chalcicoidea abundance decreased with herbaceous richness and with urban cover. Ichneumonoidea abundance increased with mulch and bare ground cover, garden size, garden age, and with agriculture land cover but decreased with tree richness and urban cover. Predators removed between 15–100% of sentinel prey within 24 h but prey removal was greater in California. Generally, prey removal increased with vegetation diversity, floral abundance, mulch cover, and urban land cover, but declined with vegetation cover and bare ground. Although some factors had consistent effects on natural enemies and pest control in the two locations, many did not; thus, we still need more comparative work to further develop our understanding of general principles governing conservation biological control in urban settings.

Resumen en inglés

In order to secure the provisioning of ecosystem services, detailed analyses of the relationship between biodiversity and agriculture are required. We studied ground spider diversity in a 52 km² coffee landscape in Southern Mexico, and asked the following questions. (1) How do coffee management variables and local microhabitat variables change among coffee agroecosystems and forest sites and across seasons? (2) How does coffee management affect ground spider richness, abundance, and composition? (3) How do local and landscape factors in fl uence ground spider richness and abundance? and (4) What role does seasonality play in shaping ground spider communities? During the dry season and rainy season of 2011 we sampled ground active spiders using pitfall traps from high and low shade coffee agroecosystems (27 sites) and from forest (10 sites). On local scale, for each 20 m × 20 m site we measured leaf litter variables, invertebrate dry biomass, slope of the terrain and elevation, and management variables such as canopy cover, shade tree richness, shade tree density and proportion of Inga trees. At the landscape scale, we measured distance to the nearest forest and percent of forest in buffers of 500 m. Results show that agricultural management had a strong influence on spider richness and abundance. Across seasons, local spider richness and abundance had or tended to have higher values in the low-shade coffee. Spider richness and abundance were strongly in fl uenced by physiographic and local predictors and weakly by landscape predictors. Furthermore, predictors varied with seasonality, with slope of the terrain being the strongest predictor in the dry season and canopy cover being the strongest predictor in the rainy season. We conclude that ground active spiders in this coffee landscape are greatly in fl uenced by coffee management and local characteristics.

Biotic interactions play a central role in determining species distribution and abundance. Some ants act as keystone species affecting the distribution and abundance of other species, including spiders. In coffee plantations Pocobletus sp. spiders are significantly more abundant in coffee plants patrolled by the aggressive arboreal ants Azteca sericeasur. However, it is unknown if other ant species influence this ant–spider association, how these associates are spatially distributed, and which are the potential drivers of this association. Here we examine the influence of ants, Azteca sericeasur and Pheidole synanthropica, and coffee branch density on Pocobletus abundance in a coffee farm in southern Mexico. We also analyze the spatial distribution and abundance of Pocobletus sp., in relation to the spatial distribution of A. sericeasur and P. synanthropica. Finally, we examine prey availability and enemy-free space as potential mechanisms underlying this ant–spider association. Results show that Pocobletus abundance is positively correlated with coffee branch density and A. sericeasur and P. synanthropica presence. Furthermore, the spatial distribution analysis shows that in 20  20 m plots Pocobletus is strongly associated to A. sericeasur, but not to P. synanthropica. Results show that insect abundance in both Pocobletus’s webs and sticky traps was significantly higher in the presence of A. sericeasur whereas the abundance of the predators of Pocobletus decreased in A. sericeasur’s presence; suggesting positive direct and indirect effects of A. sericeasur on Pocobletus. Overall, this study highlights the strong influence of ants and plant characteristics on the abundance and spatial distribution of spiders as well their indirect effects on other taxa.

Resumen en inglés

Few relevant data are available to analyze how landscape structure and composition affect the abundance and movement patterns of tropical insects. Using mark-release recapture experiments we examine the effect of an agro-pasture matrix on changes in diversity and migration of frugivorous butterflies in a tropical fragmented landscape in southern Mexico. In total, 53 frugivorous butterfly species were recorded in the entire landscape. Butterfly species composition was much more similar between sites than plant composition. A total of 3,501 individuals belonging to 41 butterfly species were captured, out of which 23 species (56%) were recaptured at least once. A large fraction of individuals was recaptured at the site of release (91%). We failed to find a significant relationship between the proportion occupied by the matrix and rates of residence, emigration, and immigration. Our results suggest that matrix quality in this and other traditionally managed agro-pasture landscapes plays a key role in both keeping important levels of biodiversity and maintaining constant movements of butterflies between otherwise isolated habitat patches.

Resumen en español

La matriz es un elemento del paisaje que incide de forma importante sobre los procesos y atributos ecológicos y por tanto es de interés en el contexto de la conservación de la biodiversidad y el manejo del paisaje. El objetivo de este estudio fue evaluar el efecto de una matriz agrosilvopastoril sobre la diversidad y migración de mariposas frugívoras en cinco unidades de muestreo de un paisaje tropical, ubicado en el sureste de México. Durante marzo-abril de 2005 se realizó la caracterización de las unidades de muestreo a través de la cuantificación de la cobertura del suelo y de la superficie ocupada por la matriz. Durante mayo-octubre de 2005 se efectúo el muestreo de mariposas usando trampas Van Someren Rydon. Simultáneamente se realizó un experimento de capturamarca- recaptura para estimar la migración de mariposas en el paisaje. Los resultados señalan que 1) la riqueza de especies entre las unidades de muestreo es similar: valor inferior = 34 especies, valor superior = 40 especies, 2) la complementariedad de la comunidad de mariposas entre unidades de muestreo fue relativamente baja, complementariedad promedio = 0.30 ± 0.028 E. E. , 3) 30 % de las especies se presentó únicamente en una o dos unidades de muestreo, 4) las fracciones de migración de tres especies generalistas no mostraron variaciones importantes en las unidades de muestreo y 5) 9% de los movimientos registrados, ocurrieron entre 100 m y 1450 m. Los resultados de este estudio sugieren que la diversidad y migración no son afectadas de forma importante por la matriz, al menos para el gremio estudiado y las condiciones espacio temporales del paisaje estudiado.

Sin embargo, para asegurar la persistencia a largo plazo de las especies con distribución restringida es necesario realizar un manejo de la matriz agrosilvopastoril por la que diferentes especies transitan en búsqueda de plantas hospederas, parejas y sitios de descanso.

Resumen en inglés

The unique butterfly species, Baronia brevicornis, perhaps the oldest taxon in the Papilionidae, is known to have a very restricted distribution in Mexico. Populations are restricted to southern Mexico in deciduous scrub forest where its host-plants, Acacia trees (Leguminosae), are common and widespread. Little is known of the conservation implications of its relationship with its host trees. We recorded fine scale population data for larval and adult B. brevicornis in 22 km2 of fragmented landscape in southern Mexico. Habitat associations determined from over 1319 transect walks reveal that B. brevicornis exhibited an extremely localised distribution, occupying <1% of the study area and being mostly associated with Acacia woodlots.

Detailed analyses of habitat requirements for larva and/or adult B. brevicornis suggest that it lays its eggs on Acacia pennatula and A. macracantha (two newly recorded larval host-plants), that eggs were laid disproportionately on Acacia trees with long branches (χ2 =17.7, P<0.001) and that the probability of finding adult B. brevicornis between occupied and un-occupied Acacia woodlots increased with host-plant density (χ2 =18.4, P<0.001). The results of this study suggest that conservation recommendations for B. brevicornis must consider the condition of the Acacia habitat network, given that Acacia is mostly associated with humanmanaged grazing systems. Effective conservation will require the establishment of connected networks of patches where natural dynamics can produce new habitats, as well as the creation of new habitats within colonisation distance. This research provides a rare case study of conservation biology of a Neotropical insect, emphasising the importance of using ecological information to provide management recommendations.
