AbstractAnts are important pest control agents in many agroecosystems worldwide. However, little is known about how management, ecological contrast generated by different agricultural practices, and landscape complexity affect their communities and the potential pest control that they can provide.Here, we surveyed ant communities in 40 paired olive groves with different ground-herb cover management across 20 localities spanning a wide range of landscape complexity at the regional scale. We also conducted experiments with dummy plasticine models in 18 of these groves to explore the ant potential to control the two main pests of the olive tree (olive moth and olive fly). In addition, we calculated an index, the Ant-community Predation Function (APF), which informs about the predation pressure exerted by ant communities over these pests.Results show that: a) extensive management at intermediate landscape complexity maximizes the abundance and pest control by ants; b) the ecological contrast affects ant abundance and ant richness but does not impact the predation function; c) APF is a good measure of pest control potential at the community level; and, d) Tapinoma nigerrimum is an important ant species for pest control in our system, which seems little affected by local or landscape heterogeneity.This study advances our knowledge about local management and landscape effects on ants and their potential contribution to pest control in olive groves. Extensive herb cover management and landscape heterogeneity increased ant predation pressure in olive groves.

Seasonal Population Dynamics

Abstract Bactrocera oleae is the main pest in olive groves and its management requires a sustainable perspective to reduce the use of chemical products. Landscape context is being considered as an important driver of pest reduction but results on B. oleae show inconsistency to date. Most of landscape-pest control studies focus on the dynamics of the pests within the focal crop, ignoring these dynamics in other land uses. Here we present a study in which we analyze the seasonal population dynamics of the olive pest B. oleae in the most important land uses of a typical olive landscape in Portugal. We found that B. oleae is present in all the land uses and the dynamics are very similar to those in the olive groves. However, the presence of these land uses in the landscape did not display any increase of B.oleae abundance within the olives groves. In contrast, a landscape mainly composed by olive groves increased the abundance of this pest. Importantly, more diverse landscapes surrounding olive groves reduce the abundance of the olive fly. Based on these findings, we can conclude that B. oleae is present in all the land uses of the studied landscape but that this presence does not imply an increase of B. oleae in olive groves. Indeed, other land uses can promote landscape diversification which is a driver of the reduction of B. oleae populations in olive groves. We thus encourage olive stakeholders to increase landscape diversification around their farms by promoting/restoring other crops/habitats.

The present study deals with the ant community variation in and around Aurangabad city. During the study total 16 species of ants belonging to twelve genera and four subfamilies were reported in eight habitat from urban and periurban regions. Abundance of ants was more in peri-urban region as compared to urban region. Subfamily myrmicinae was more dominant as compared to other subfamilies. Seasonal abundance of ants was seen to be more in winter season and less in rainy season.
