• Green peach aphid

  General The green peach aphid ( Myzus persicae subsp. persicae ) is an important insect pest in sweet pepper , tomato , cucumber and many other greenhouse crops. The aphid may originate from Asia, where its winter-hardy host plant, the peach tree, is native, however it is now a pest with a world-wide distribution. The green peach aphid ( Myzus persicae subsp. persicae ) is a particularly polyphagous aphid with summer host plants from more than 40

• Western flower thrips

  General The western flower thrips (Frankliniella occidentalis) is currently the most damaging thrips species in many greenhouse crops. The western flower thrips (Frankliniella occidentalis) can be found on a wide variety of plants, including many vegetable and ornamental crops in greenhouses, and on various weeds. It is an especially significant pest in cucumber , sweet pepper , eggplants, and many ornamental crops. Damage symptoms Thrips cause

• Spider mites and other mites

  Biological control of spider mites and other mites Spider mites and other mite species can rapidly infest greenhouse and field crops, feeding on plant cells and causing leaf discoloration, reduced photosynthesis and lower yields. Their fast reproduction makes early detection and continuous control essential for maintaining healthy, productive crops. Biological control of spider mites and other mites uses a range of natural enemies that target

• Thrips

  Biological control of thrips Thrips are among the most challenging pests in greenhouse and field crops. Their feeding and virus transmission cause leaf deformation, silvering and fruit damage, leading to reduced yield and marketability. Because they reproduce quickly and hide deep within flowers and leaves, effective thrips control requires an integrated biological approach. Biological control of thrips combines several complementary solutions that

• Aphids

  Biological control of aphids Aphids are among the most harmful pests in greenhouse and field crops, causing plant stress, virus transmission and yield loss. Effective aphid control is essential for maintaining healthy, productive crops. Biological control of aphids uses a combination of natural enemies that attack aphids in different ways: Parasitic wasps Predatory gall midges Ladybirds Lacewings These beneficial insects target aphid populations and

• Tobacco aphid

  General The tobacco aphid ( Myzus persicae subsp. nicotianae ) probably evolved from the peach potato aphid in the Far East and is a key pest of tobacco crops in both the United States and South America. The tobacco aphid ( Myzus persicae subsp. nicotianae ) is also encountered in a range of crops in greenhouses, such as sweet pepper , aubergine, chrysanthemum , and various pot plants and cut flower crops. Damage symptoms Nymphs and adults extract

• Leaf miners

  Biological control of leaf miners Leaf miners are damaging pests that tunnel through leaves, reducing photosynthesis and weakening plant growth. Their feeding patterns cause visible leaf damage, lower crop quality and can open the way for secondary infections. Effective leaf miner control is essential to protect plant vitality and maintain marketable yields. Biological control of leaf miners combines effective natural enemies and monitoring tools to

• Tomato leafminer

  General The tomato leaf miner (Tuta absoluta), a major pest of field- and greenhouse-grown tomatoes, belongs to the family of Gelechiidae . It is oligophagous, feeding mainly on Solanaceae species . The main host is tomato but it also feeds on other solanaceous crop plants including potato , eggplant, capsicum pepper and tobacco as well as weeds such as Datura stramonium, Lycium chilense , and Solanum nigrum. Damage symptoms The most

• Whitefly

  Biological control of whitefly Whiteflies are common pests in greenhouse and field crops, feeding on plant sap and transmitting harmful viruses. Their feeding weakens plants, causes leaf yellowing and leads to honeydew deposits that reduce crop quality. Effective whitefly control is essential to maintain healthy, productive crops and prevent the spread of diseases. Biological control of whiteflies uses a combination of natural enemies and tools

• Greenhouse whitefly

  General The greenhouse whitefly ( Trialeurodes vaporariorum ) is one of the major pests of vegetable and ornamental crops in greenhouses throughout the world. The greenhouse whitefly ( Trialeurodes vaporariorum ) originally comes from tropical and subtropical America, probably Brazil or Mexico. Hundreds of plant species from different families serve as suitable hosts for this whitefly. It occurs on many crops, including aubergine, beans, cucumber ,
