The food eaten by M. caliginosus clearly had a major impact on most parameters of its life cycle. When either greenhouse whiteflies, Trialeurodes vaporariorum (Westwood); eggs of Ephestia kuehniella Zeller, or potato peach aphid, Myzus persicae Sulzer were offered as preys, during development M. caliginosus had high survival percentage (80%, 79% and 64% respectively) and developed more quickly with duration of development of (17.4, 15.6 and 15.7 days respectively) and were able to produce new generations. However, when greenhouse red spider mites, Metatetranycc chus urticae Koch or broad bean aphid, Aphis fabae Scopoli were offered as preys, the predator had high mortality (67% and 50% respectively), longer development, and shorter adult longevity and produced no offspring. The results also showed that M. caliginosus could obtain some nutrients from plants, as 10% of M. caliginosus nymphs survived to the fourth instar when reared on clean leaves of Pelargonium peltatium, although they did not survive to the adult stage.

It is mainly used as a biological control auxiliary against T. vaporariorum Westwood (Homoptera: Aleyrodidae). The greenhouse whitefly, Trialeurodes vaporariorum is particularly harmful to tomato plants grown under the greenhouse. It has become prevalent whenever crops are frequently sprayed with insecticides. Biological control is becoming important for controlling this insect pest. A mirid bug management programme has been developed for an Integrated Pest Management (IPM) in tomato. The objective of the programme was to keep the predator population densities high enough in order to maintain T.

  • Dicyphus Hesperus) Whitefly Predatory Bug
    SHEET 223 - DICYPHUS Dicyphus (Dicyphus hesperus) Whitefly Predatory Bug Target Pests Greenhouse whitefly (Trialeurodes vaporariorum), Tobacco whitefly (Bemisia tabaci). Dicyphus will feed on two-spotted spider mite (Tetranychus urticae), Thrips and Moth eggs but will not control these pests. Plants Note: Since Dicyphus is also a plant feeder it should not be used on crops such as Gerbra which can be damaged. Most of the work with Dicyphus has been on vegetable crops such as tomato, pepper and eggplant where it will not cause plant damage by plant feeding. Description The predatory bug, Dicyphus hesperus is similar to Macrolophus caliginosus, which is being used in Europe to control whitefly, spider mites, moth eggs and aphids. The use of Dicyphus is being studied by D. Gillespie (Agriculture and Agri-Foods Canada Research Station, Agassiz, BC). Dicyphus should not be used on its own to replace other biological control agents. It is best used along with other biological control agents in greenhouse tomato crops that have, or (because of past history) are expected to have. whitefly, spider mite, or thrips problems. • Eggs are laid inside plant tissue and are not easily seen. • Adults are slender (6mm), black and green with red eyes and can fly • Nymphs are green with red eyes Use in Biological Control • Release Dicyphus as soon as whiteflies are found, early in the season at a rate of 0.25-0.5 bugs/m2 (10 ft2) of infested area; repeat in 2-3 weeks. • Release batches of 100 adults together in one area where whitefly is present or add supplementary food (frozen moth eggs: i.e.

Another mirid predator, Dicyphus tamaninii Wagner, spontaneously colonizes Mediterranean greenhouses. The impact of the presence of D. tamaninii on predation of the greenhouse whitefly (Trialeurodes vaporariorum Westwood) by M. caliginosus was investigated in the laboratory on tomato plants during four days. No significant interspecific competition was recorded between mirid nymphs and no significant intraguild predation was observed. Higher level of predation of the whitefly populations was achieved by D. tamaninii alone, than by M. caliginosus alone. Predation by the heterospecific combination (M. caliginosus + D. tamaninii) was similar to the results obtained by conspecific treatments. No intraspecific competition was recorded with D. tamaninii, nor with M. caliginosus. Finally, the distribution of whitefly predation on the plant by the mirids changed according to the predator treatment. The heterospecific combination of both mirids had a higher predation rate on lower leaves of the plant than monospecific combinations. Overall, the presence of D. tamaninii did not disrupt whitefly predation by M. caliginosus and could even increase the level of predation. Ó 2002 Elsevier Science (USA). All rights reserved.

Simple Summary: Biological control (BC) is an effective way to regulate pest populations in hor- ticultural crops, allowing the decrease of pesticide usage. On tomato, predatory insects like plant bugs or mirids provide BC services against several insect pests. Native predators are adapted to local conditions of climate and ecology and therefore may be well suited to provide BC services. Dicyphus cerastii is a predatory mirid that is present in the Mediterranean region and occurs in tomato greenhouses in Portugal. However, little is known about its contribution to BC in this crop. In this study, we evaluated how prey consumption is affected by increasing prey abundance on four different prey, in laboratory conditions. We found that the predator can increase its predation rate until a maximum is reached and that prey characteristics like size and mobility can affect predation.

  • Macrolophus Pygmaeus (Rambur) As an Efficient Predator of the Tomato Leafminer Tuta Absoluta (Meyrick) in Europe
    B A S E Biotechnol. Agron. Soc. Environ. 2014 18(4), 536-543 Focus on: Macrolophus pygmaeus (Rambur) as an efficient predator of the tomato leafminer Tuta absoluta (Meyrick) in Europe. A review Lara De Backer, Rudy Caparros Megido, Éric Haubruge, François J. Verheggen University of Liege - Gembloux Agro-Bio Tech. Unit of functional and evolutionary Entomology. Passage des Déportés, 2. B-5030 Gembloux (Belgium). E-mail: [email protected] Received on June 21, 2013; accepted on May 28, 2014. The tomato leafminer, Tuta absoluta (Meyrick), originates from South America, and remains one of the main tomato pests in this continent. Since its introduction to Europe in 2006, Mediterranean countries have also been exposed to this pest. Because of the endophytic habits of the larvae and ability of adults to reproduce parthenogenetically, chemicals and sexual pheromone- based control methods generate poor results. Recently, the use of biocontrol agents, such as Macrolophus pygmaeus Rambur (Heteroptera: Miridae), has been investigated as an alternative means of control, the results of which are presented in this review. Macrolophus pygmaeus is a mirid bug that is widely used to control different phytophagous insects in integrated pest management strategies through Europe. Several studies have confirmed the high predation potential of M. pygmaeus on T. absoluta under laboratory and semi-field conditions. This predator spontaneously colonizes tomato greenhouses in the southern Mediterranean countries. The use of banker plants (i.e., plants that provide a habitat to the predator) improves the colonization ability of this natural enemy. Hence, if the local population size is low, an augmentative strategy could be adopted.

  • How Safe Is It to Rely on Macrolophus Pygmaeus (Hemiptera: Miridae) As a Biocontrol Agent in Tomato Crops?
    ORIGINAL RESEARCH published: 10 September 2018 doi: 10.3389/fevo.2018.00132 How Safe Is It to Rely on Macrolophus pygmaeus (Hemiptera: Miridae) as a Biocontrol Agent in Tomato Crops? Juan A. Sanchez*, Elena López-Gallego, María Pérez-Marcos, Luis G. Perera-Fernández and María J. Ramírez-Soria Department of Crop Protection, Biological Control and Ecosystem Services, Instituto Murciano de Investigación y Desarrollo Agrario y Alimentario, Murcia, Spain Omnivorous mirids (Hemiptera: Miridae) are unusual as biocontrol agents, as they feed on both plants and pests. Therefore, extensive knowledge of their ecological behavior is required to maximize their predatory side and to minimize crop damage. Macrolophus pygmaeus is a known predator of small arthropods, used in European tomato crops for more than 20 years. This mirid is currently considered harmless to tomato, although some controversy remains in relation to the status of the species. The aim of this work was to investigate the benefits that M. pygmaeus provides as a predator and the likely damage as a plant feeder. The experiment was carried out in 6 experimental Edited by: greenhouses in southern Spain.

We studied the biological control of Liriomyza leafminer species, especially L. sativae Blanchard and L. trifolii (Burgess) (Diptera: Agromyzidae), on glasshouse tomatoes using parasitoid complexes from C. horticola. Garden pea and tomato plants were collected in Shizuoka Prefecture, Japan, between April and May 2004. The numbers and species of leafminers and the parasitoids emerging from them were determined. Species of leafminers and parasitoids. Liriomyza sativae, L. trifolii, and L. bryoniae 70 (Kaltenbach) were collected from tomato plants, whereas C. horticola was mainly col- lected from the garden pea. Liriomyza leafminers were very rare on garden peas and their occurrence was limited to summer. The predominant parasitoids on the garden pea were Diglyphus isaea (50.5%), Chrysocaris pentheus (25.6%), Neochrysocaris formosa (10.8%), and C. pubicornis (7.5%) (Hymenoptera: Eulophidae). The former three para- sitoid species were also frequently collected from tomato plants, suggesting that parasi- toids of C. horticola also commonly parasitize Liriomyza leafminers. Emergence of parasitoids. About 15 parasitoids emerged per 10 leaves. Ninety percent of parasitoids had emerged from garden peas on the 24th, 18th, and 15th day at 20°C, 25°C and 15°C, respectively (Table 1).

  • Macrolophus Pygmaeus (Rambur) March 2014
    EPA report Import and release of Macrolophus pygmaeus (Rambur) March 2014 Advice to the Decision Making Committee on application APP201254: – To import and release Macrolophus pygmaeus as biocontrol agents for whitefly (Trialeurodes vaporariorum), under section 34 of the Hazardous Substances and New Organisms Act 1996 www.epa.govt.nz 2 Application for approval to import and release Macrolophus pygmaeus (APP201254) Executive Summary and Recommendation In November 2013, Tomatoes New Zealand made an application to the Environmental Protection Authority (EPA) seeking to import and release Macrolophus pygmaeus for use as an augmentative biocontrol agent to control greenhouse whitefly in tomato glasshouses. Their application stems from the desire to improve the competitiveness of the New Zealand tomato industry. The applicant asserts the key to improving competitiveness is the use of Integrated Pest Management (IPM) to manage pests in commercial glasshouses. Not only does this approach offer cost savings, it can reduce the use of harmful chemical inputs; improving people’s health, lowering environmental impacts and increasing the export potential of the product. We consider that IPM can, in the right circumstances, provide a win-win solution to both consumers and producers and we applaud this focus by the industry. Integrated Pest Management by original definition is the integration of biocontrol with chemical applications, so that the latter have least impact on natural enemies. Thus a significant aspect of this approach is the use of natural enemies to control insect pests. This use of natural enemies has a long history both overseas and in New Zealand. To this effect the tomato industry is looking to introduce a new biological control agent (BCA), Macrolophus pygmaeus, a natural predator of the greenhouse whitefly (Trialeurodes vaporariorum).

Received: (14/1/2006), Accepted: (5/9/2006) Abstract Laboratory experiments were carried out to study the effect of photoperiod on the life history of the predator Macrolophus caliginosus Wagner [Hemiptera: Miridae] fed on eggs of the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) [Homoptera: Aleyorodidae]. Day-length had no significant effect on either nymphal mortality, development time or adult longevity of M. caliginosus. The absence of light had no negative effect on the consumption rate of M. caliginosus. However, the number of T. vaporariorum eggs consumed by the predator increased with decreasing photoperiod. Light was of significance for the development of the predator embryos during incubation period as no hatching occurred under continuous darkness, but hatching was reduced at 8L:16D in comparison to hatching at 16L:8D. Key words: Photoperiod, Life history, Macrolophus caliginosus, Trialeurodes vaporariorum, laboratory experiments. ﻣﻠﺨﺺ Effect of Photoperiod on the Life History of the“ ـــــــــــــــــــــــــــــــــــــــــــــــــــ 136 ……” ﺗﻢ إﺟﺮاء أﺑﺤﺎث ﻣﺨﺒﺮﻳﺔ ﻟﺪراﺳﺔ ﺗﺎﺛﻴﺮ ﻣﺪة ﻓﺘﺮة اﻻﺿﺎءة ﻋﻠﻰ دورة ﺣﻴﺎة اﻟﺒﻖ اﻟﻤﻔﺘﺮس Macrolophus caliginosus Wagner ﻋﻨﺪ ﺗﻐﺬﻳﺘﻪ ﻋﻠﻰ ﺑﻴﻮض ذﺑﺎﺑﺔ اﻟﺒﻴﻮت اﻟﺰﺟﺎﺟﻴﺔ اﻟﺒﻴﻀﺎء (Trialeurodes vaporariorum (Westwood ﻟﻘﺪ وُ ﺟ ﺪَ أن ﻓﺘﺮة اﻻﺿﺎءة ﻟﻴﺲ ﻟﻬﺎ ﺗﺎﺛﻴﺮات ﻣﻌﻨﻮﻳﺔ ﻋﻠﻰ أي ﻣﻦ ﻣﻌﺪﻻت وﻓﻴﺎت ﺣﻮرﻳﺎت اﻟﺒﻖ أو ﻓﺘﺮة اﻟﺘﻄﻮر أو ﻣﺪة ﺣﻴﺎة اﻟﺤﺸﺮات اﻟﻜﺎﻣﻠﺔ.
