Parthenothrips dracaenae
characteristics: leaf inhabiting thrips species, adult thripses mostly on the upper side of the leaf; larvae in groups on the underside of the leaf, adults have a remarkable pattern of dark bands across their wings, larvae white, moderately translucent, widely distributed in glasshouses in northern Europe; often on house plants natural enemies: Franklinothrips vespiformis hosts: allmost all ornamental foliage plants |
Heliothrips haemorrhoidalis
characteristics: leaf-inhabiting thrips; about 1,5 mm. in size, on upper- as well as underside of the leaves, adult traipses dark in colour, legs are bright, proximal part of the wings is bright coloured; wings create a bright band lengthwise across the thrips, larvae are yellow, often with a dark dot; they carry a drop of excrements at the distal part of their body, occurs frequently in glasshouses in temperate regions; in (sub) tropical regions it can occur outside on several trees and shrubs natural enemies: Thripobius semiluteus hosts: many different host plants |
Echinothrips americanus
characteristics:leaf inhabiting thrips; about 1,2 mm. in size, adult thripses are dark coloured, legs dark as well; body slender, proximal part of the wings pointed; rest of the wings translucent, larvae are white, translucent; they carry a droplet of excrements at the distal part of their body, larvae pupate on the leaf, they prefer the underside of the leaves but occur at the upper side and in flowers as well, mainly in the bottom layer of the vegetation, in northern Europe only in greenhouses natural enemies: Franklinothrips vespiformis Waardplanten: e.g. Dieffenbacchia, Hibiscus, sweet pepper |
characteristics: leaf inhabiting thrips; about 1,5 mm. in size, on the upper- as well as the underside of leaves, adult thripses are dark coloured, legs mostly dark as well, wings are dark with 3 bright bands, larvae yellow, often with dark dot; they carry a droplet of excrements at the hind part of their body, in northern Europe indoors as well as outdoors natural enemies: Franklinothrips vespiformis, Thripobius semiluteus hosts: often on monocotyledons |
Frankliniella occidentalis
characteristics: about 1,3-1,4 mm. in size, adult thripses are yellow to orange coloured, adults mainly in the upper part of the plants, flower buds as well as new growth can be heavily distorted due to infestation of western flower thrips, thripses prefer flower buds, this species is also eating pollen, so occurs often in flowers, pupation takes place in the ground, no diapause, can transmit viruses, closely resembles Thrips tabaci natural enemies: Amblyseius cucumeris, Amblyseius swirskii, Orius spp., Hypoaspis aculeifer, Hypoaspis miles, Franklinothrips vespiformis hosts: many different greenhouse vegetables as well as ornamental plants |
Thrips tabaci (tabakstrips)
characteristics: about 0,8 -1,2 mm. in size, colour of adult thripses depending on the food, mostly occurs along the major veins, damage mostly on the leaves, pupation takes place in the ground, diapausing occurs, can transmit viruses, much alike western flower thrips natural enemies: Amblyseius cucumeris, Amblyseius swirskii, Orius spp., Hypoaspis aculeifer , Hypoaspis miles hosts: many different greenhouse vegetables as well as ornamental plants |
