Entomopathogenic nematodes (EPN) are excellent biocontrol agents against various insect pests. Novel biotechnological approaches can enhance their utility against insects above-ground, opening a new venue for selecting superior EPN against certain insects. We hypothesize that different populations of the same species but from different origins (hab...

Ecologists study how populations are regulated, while scientists studying biological pest control apply population regulation processes to reduce numbers of harmful organisms: an organism (a natural enemy) is used to reduce the population density of another organism (a pest). Finding an effective biological control agent among the tens to hundreds...

Several cucurbits species are cultivated in greenhouses worldwide. The most important genera are (1) Cucurbita, which includes squash, pumpkin, zucchini and gourds, (2) Citrullus, which includes watermelon and (3) Cucumis, which includes cucumber and various melons. Pests and diseases affecting cucurbit crops can vary considerably in relation to ge...
Conference Paper
The banana mealybug (Dysmicoccus grassii) is a major pest in banana plantations in the Canary Islands, for which chemical control is becoming ineffective and more restricted due to new governmental regulations and consumer preferences for pesticide residue free products. Consequently, alternative control methods, such as biological control, are rec...
Article
Dicyphus hesperus Knight (Heteroptera: Miridae) can contribute to the suppression of populations of Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) and Bactericera cockerelli Sulcer (Hemiptera: Psyllidae) in tomato. Nevertheless, the remaining levels of these pests could still be too high for the crop to tolerate. We thus tested here whether the...
Article
Tuta absoluta (Meyrick; Lepidoptera: Gelechiidae) is a key pest of tomato and is quickly spreading over the world. We conducted an experiment aimed at evaluating the control capacity and risk for plant damage of three Neotropical mirid species, Campyloneuropsis infumatus (Carvalho; Hemiptera: Miridae), Engytatus varians (Distant; Hemiptera: Miridae...

The potential of the mirid predator Dicyphus hesperus Knight (Heteroptera: Miridae) as a biological control agent of the sweetpotato whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) and the potato psyllid, Bactericera cockerelli Sulcer (Hemiptera: Psyllidae) in tomato was investigated in two experiments. The first experiment focused on t...
Article
Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) and Bactericera cockerelli Sulcer (Hemiptera: Psyllidae) are important pests in tomato, and the mirid Dicyphus hesperus Knight (Heteroptera: Miridae) has been shown as an effective predator of both pests. Although the predator was able to suppress populations of both pests, the remaining levels coul...

The predators Macrolophus basicornis (Stal), Engytatus varians (Distant) and Campyloneuropsis infumatus (Carvalho) consume large numbers of tomato pests such as Bemisia tabaci (Gennadius) and Tuta absoluta (Meyrick). However, they are zoophytophagous and feed on plant parts as well. We evaluated the type and effect of injury caused by nymphs and ad...
Article
Necremnus tutae is native to the Mediterranean region where it has been observed in greenhouses parasitizing the invasive Tuta absoluta on tomato. The objective of the present study was to determine whether augmentative releases of N. tutae can improve existing biological control of T. absoluta based on predation by Nesidicoris tenuis. Two experime...
Article
The potato psyllid, Bactericera cockerelli Sulcer (Hemiptera: Psyllidae), and the sweetpotato whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), are major pests in tomato in the USA, Mexico, and Central America. Earlier research revealed that the mirid bug Dicyphus hesperus Athias-Henriot (Heteroptera: Miridae) has favorable rates of deve...
Article
The predatory mite Amblyseius swirskii quickly became one of the most successful biocontrol agents in protected cultivation after its introduction into the market in 2005 and is now released in more than 50 countries. There are several key factors contributing to this success: (1) it can control several major pests including the western flower thri...
Article
Necremnus artynes is native to the Mediterranean region where it has been observed in greenhouses parasitising Tuta absoluta on tomato. In this study, we evaluated the suitability of the different instars of T. absoluta as hosts for N. artynes and the life-history traits of N. artynes at three different temperature regimes (20, 25 and 30°C) on thir...
Article
Nesidiocoris tenuis Reuter (Het.: Miridae) is widely used as a biological control agent of whiteflies and other pests in greenhouse-grown tomatoes. It is typically released augmentatively some weeks after transplanting and needs several weeks to establish. Releasing N. tenuis prior to transplanting could accelerate its establishment. However, timin...
Article
The predatory mite Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) has been evaluated as a potential biological control agent for whitefly and thrips, but it has yet to be demonstrated that the addition of A. swirskii to an existing biological control programme improves management of these pests in commercial greenhouses. Experiments were...
Article
An early release system developed for Nesidiocoris tenuis Reuter (Heteroptera: Miridae) could provide a good control of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in tomato. Tuta absoluta and the whitefly Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) often appear simultaneously in tomato crops and this might affect control capacity. The...
Article
The two-spotted spider mite Tetranychus urticae and the tomato red spider mite Tetranychus evansi are known to cause severe damage in tomato crops. Preliminary laboratory studies showed that a phytoseiid predatory mite from Argentina, Phytoseiulus longipes, could be a potential candidate for the control of those two pests. The present paper aims to...
