A Fundamental Step in IPM on Grapevine: Evaluating the Side Effects of Pesticides on Predatory Mites

Insects, 2015
Knowledge on side effects of pesticides on non-target beneficial arthropods is a key point in Integrated Pest Management (IPM). Here we present the results of four experiments conducted in vineyards where the effects of chlorpyrifos, thiamethoxam ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Effect of Leaf Removal and Insecticide Applications on Population Densities of Leafhoppers and Mites Associated with Grapevines

Insects, 2023
In this study, we tested the effects of mechanical leaf removal, insecticide application, and their interaction on leafhoppers and phytophagous and predatory mites occurring in two vineyards over three growing seasons.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Determination of spider mite abundance in soil of field-grown cucumbers and in plants under predatory mite pressure in invasive infestations using HRM real-time PCR assay.

PLoS ONE, 2022
The two spotted spider mite, Tetranychus urticae Koch L. (Acari: Tetranychidae), is a plant pest that can lead to severe economic losses in open field cucumber cultivation.

Two predatory mite species as potential control agents of broad mites [PDF]

BioControl, 2017
The broad mite is a key pest of various crops worldwide, including chili pepper (Capsicum frutescens), where it is controlled with chemical pesticides. Two phytoseiid predators (Amblyseius herbicolus and Neoseiulus barkeri) and a blattisociid mite species (Lasioseius floridensis) occur in association with the broad mite in Brazil.

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

Entomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.
