Banker plants and landscape composition influence colonisation precocity of tomato greenhouses by mirid predators

Functional Responses of Three Neotropical Mirid Predators to Eggs of Tuta absoluta on Tomato

Tuta absoluta (Meyrick) has quickly developed into a significant tomato pest worldwide. While the recently found mirid predators Macrolophus basicornis (Stal), Engytatus varians (Distant) and Campyloneuropsis infumatus (Carvalho) of this pest are able to establish and reproduce on tomato, biological knowledge of these mirids is still limited. Here we describe the functional response of the thre...

Trophic relationships between predators, whiteflies and their parasitoids in tomato greenhouses: a molecular approach.

The whiteflies Bemisia tabaci Gennadius and Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) are two of the main pests in tomato crops. Their biological control in Mediterranean IPM systems is based on the predators Macrolophus pygmaeus (Rambur) and Nesidiocoris tenuis Reuter (Hemiptera: Miridae), as well as on the parasitoids Eretmocerus mundus (Mercet) and Encarsia pergandiella H...

Vegetative growth and chemical composition of tomato plants as affected by different types of salt stress and zinc fertilization

Alternative control of Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae) on tomato plants grown in greenhouses.

Tetranychus evansi Baker & Pritchard is an important pest of solanaceous plants, including tomatoes. This mite is characterized by a high reproductive rate, which leads to high population growth in a short period of time causing important economic damage. Control of T. evansi is mainly through synthetic acaricides. In searching for environmentally friendly control measures, we evaluated the eff...

Toxicity Effect of Three Insecticides on Important Pests and Predators in Tomato Plants

The objective of this study was to evaluate insecticide toxicity on Bemisia tabaci, Tetranychus evansi, Orius insidiosus, Cycloneda sanguinea and Chauliognathus flavipes in tomato plants. The following toxicity treatments were applied: T1: control, T2: chlorpyrifos (Pitcher) 450 EC (1.25 L.ha), T3: chlorpyrifos 450 EC (Pitcher) (0.62 L.ha), T4: thiamethoxam 100 WG (1.00 L.ha), T5: thiamethoxam ...
