  author={Filipe Madeira and Eva Edo and Samuel Sossai and J Callizo and Ramon Albajes},
Slow establishment and risks of plant damage are major constraints for the use of the predatory mirid bugs that are commercially available for release in greenhouse crops. Therefore, a new interest has turned towards two predatory Dicyphus species (Heteroptera: Miridae) that have been investigated in the past but have not been used commercially in augmentative biological control. We assessed their development duration and survival at temperature and day length of summer and winter conditions… Expand

Biological Control Potential and Drawbacks of Three Zoophytophagous Mirid Predators against Bemisia tabaci in the United States
USA’s established mirid species could be immediately available to help manage existing and future invasive pests of tomato, showing a benefit of the plant-feeding habit of these predators. Expand
Impact of prey supply levels on growth performance and optimization of the mass rearing of an omnivorous mirid predator
A detailed assessment of prey deprivation effects on the developmental traits of the omnivorous predator Dicyphus errans (Wolff) (Hemiptera: Miridae) is presented and the adaptation strategies exhibited by this predatory bug are discussed. Expand
Compatibility of Nesidiocoris tenuis and Iphiseius degenerans with insecticides, miticides and fungicides used in tomato crops
Nesidiocoris tenuis (Reuter) (Heteroptera Miridae) and Iphiseius degenerans (Berlese) (Acari Phytoseiidae) are omnivorous predators commonly used in IPM in Europe. The aim of this work was to assessExpand
Exploring the Role of Supplemental Foods for Improved Greenhouse Biological Control
The current stage of knowledge associated with various supplemental food types, which work best to support specific beneficial arthropods as well as some tools and techniques for successfully applying this biological control-enhancing strategy are summarized. Expand


Evaluation of the effectiveness of Dicyphus errans (Wolff) as predator of Tuta absoluta (Meyrick)
The suitability and effectiveness of the predatory bug Dicyphus errans (Wolff) (Hemiptera: Miridae), an indigenous species usually found in the IPM tomato crop of northwestern Italy, were evaluated on eggs and larvae of T. absoluta under controlled conditions and can be considered a promising potential candidate for controlling the pest. Expand
Release rate for a pre-plant application of Nesidiocoris tenuis for Bemisia tabaci control in tomato
Evaluating different release rates for releasing N. tenuis prior to transplanting for maximizing control capacity and minimizing injury to crop found all significantly reduced the population of whitefly and gave adequate control of the pest. Expand
The predatory mirid Dicyphus maroccanus as a new potential biological control agent in tomato crops
Results suggest that D. maroccanus could play a significant role in T. absoluta-infested plants management and the potential of this zoophytophagous predator as a biocontrol agent on tomato crops is discussed. Expand
Evaluation of Dicyphus hesperus for biological control of sweet potato whitefly and potato psyllid on greenhouse tomato
The results demonstrate that implementation of augmentative releases of D. hesperus would improve biologically-based management strategies in tomato and presumably help to increase adoption of such programmes in tomato in North America. Expand
Pollen as an alternative food for Harmonia axyridis
The exploitation of pollen and other plant foods at times when insect prey is scarce, may offer a further competitive advantage to the non-indigenous coccinellid H. axyridis over native European predatory lady beetles that share the same niche and are less capable of using pollen as an alternative food. Expand
Do nymphs and adults of three Neotropical zoophytophagous mirids damage leaves and fruits of tomato?
The results indicate that nymphs and adults of these zoophytophagous mirids cause little injury to tomato seedlings and fruit, even when present in high densities and in the absence of prey, making them interesting candidates for biological control. Expand
Experimental studies on Tuta absoluta (Meyrick) in protected tomato crops in France: biological control and integrated crop protection
The predator Macrolophus pygmaeus and the parasitoid Trichogramma achaeae were studied, alone and in combination, and the possible effect of the concurrent prey Trialeurodes vaporariorum on the impact of the predator on T. absoluta was also studied. Expand
A comparative life history study of two mirid bugs preying on Tuta absoluta and Ephestia kuehniella eggs on tomato crops: implications for biological control
The results support previous studies on the potential of N. tenuis has as biological control agent of T. absoluta, and indicate that the role of M. pygmaeus in controlling T.Absoluta in the absence of other food sources is possibly limited. Expand
Plant damage to vegetable crops by zoophytophagous mirid predators
Understanding when and why plant-feeding predators increase their feeding on plants or on certain plant parts is of crucial importance for integrating them in biological control programs. Expand
Predatory capacity of two mirid bugs preying on Bemisia tabaci
The present study aimed to examine the potential of D. tamaninii and M. caliginosus for biological control of B. tabaci when this species coexists with T. vaporariorum and to determine prey preference of the predators under these circumstances. Expand
