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. 

It was studied whether the spider fauna in desert crops is influenced by the surrounding landscape in a similar way to that found in temperate climates.

The abundance of parasitoids on plants that harbor their monophagous herbivorous host often correlates with host numbers. However, when hosts are polyphagous, the species-specific characteristics of the plants can affect parasitoid abundance as well. We asked whether parasitoids that attack a polyphagous host aggregate on individual plants with high host densities, and whether plant-related factors also account for the parasitoids’ abundance on the plants.
