Controlled land spreading of olive mill wastewater (OMW) is now adopted in several Mediterranean countries as a practical alternative for its disposal.

This paper focuses on the large cosmopolitan genus Xylocopa as an additional provider of agricultural pollination services. Aspects of these bees’ life-history, social organization, and foraging ecology are discussed in the context of their potential role as crop pollination agents.

We modeled the possible effect of limited kin discrimination on larval aggression in polyembryonic wasps. In these organisms, each egg divides clonally to produce several genetically identical embryos inside an arthropod host. If more than one egg is laid inside a host (superparasitism), several clones compete for the host resources. In some species, a proportion of embryos develop into sterile soldier larvae that attack competitors inside the host.

Debates on the relative importance of different factors in limiting the realized fitness of insect parasitoids and herbivores have continued for decades. We used a novel technique to estimate lifetime reproductive success in two Anagrus spp. parasitoids, whose hosts are eggs of leafhoppers that feed on grape leaves.

The South American tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is an invasive Neotropical pest. After its first detection in Europe, it rapidly invaded more than 30 Western Palaearctic countries becoming a serious agricultural threat to tomato production in both protected and open-field crops. Among the pest control tactics against exotic pests, biological control using indigenous natural enemies is one of the most promising

It was studied whether vertebrates and their impact in crop seed predation are related to the percentage of natural (chaparral) and semi-natural habitat (planted forest with native and exotic trees) in an agricultural landscape of Israel.

Starting in 1983, nest boxes for Barn Owls Tyto alba were erected as part of a biological pest control program to deal with rodents, in Kibbutz Sde Eliyahu, and later in other agricultural fields and plantations in the Beit She’an valley, Israel.

In this study, they measured the quality of percolating water in the vadose zone, underlying both organic and conventional intensive greenhouses.

The overall objective of the present study was to determine the loading limits of composts that should be applied annually to irrigated wheat.
