Thripobius javae (= semiluteus) sluipwesp tegen trips
Appearance: The adults of Thripobius are ± 0,6 mm in length. The head and the thorax are black coloured. The abdomen is yellow with dark spots. The legs and the antennae are yellow. All adults are females. Trips larvae, parasitized by Thripobius, are yellow in the beginning and later on they turn into black cocoons. These cocoons are irregular shaped. You can often find them in groups on the underside of the leaves. The adult parasitic wasp leaves the cocoon by tearing it into pieces. Effect/Activity: The parasitic wasp Thripobius is effective in controlling the trips species Heliothrips haemorrhoidalis; it is less effective in controlling other trips species, like Hercinothrips femoralis. Thripobius mainly parasitizes small trips larvae. A female lays one egg in a trips larva. Ants disturb Thripobius in its activity. Conditions: Thripobius likes high temperatures (18-30ºC) and a high light intensity. It is effective at lower as well as higher humidity levels. Biology: At 25ºC the development from egg to adult takes about 22 days. Female don't need males to lay eggs. For Thripobius males are not known. A Thripobius female can live for a maximum of 10 days. During her lifetime she lays about 40-60 eggs; most of them on the second day. Application: THRIPOBIUS SEMILUTEUS can be used in botanical gardens, interior landscapes, zoo's and research greenhouses. |

Franklinothrips vespiformis predatory thrips against thrips
Appearance: Adult females of Franklinothrips are 2-3 mm long; their body is black with banded black and white wings and a white band at the base of the abdomen. Males are very rare. Both males and females look like ants. Larvae are bright red in colour with pale yellowish bands. Pupae can be found at the underside of the leaf, covered by a white tiny skin, along the veins. Effect/Activity: Franklinothrips is a predator of several trips species, mainly Parthenothrips dracaenae and Echinothrips americanus; other trips species are also preyed upon for example Frankliniella occidentalis. Both larvae and adults of Franklinothrips are predacious, sucking from trips adults and larvae. Pre-pupae and pupae of leaf inhabiting trips species are also eaten by Franklinothrips. Conditions: Franklinothrips is not very critical towards temperature and humidity. It is best active when temperature is above 18ºC. In winter Franklinothrips is less effective. Although no diapause occurs. Biology: Development from egg to adult is completed in approximately 3,5 weeks at 25ºC. Adult survival depends on the presence of prey or alternative food, like spider mite, young aphids or pollen. A female of Franklinothrips can live for a maximum of two months. Females can produce eggs without mating. During her entire life-span a female can lay 150 - 200 eggs. The eggs are usually laid in soft stem parts and leaves, difficult to recognize. Application: FRANKLINOTHRIPS VESPIFORMIS can be used in botanical gardens, zoo's, interior landscapes, research greenhouses, nurseries with ornamental plants as well as outdoors in (sub) tropical regions. |

Amblyseius swirskii predatory mite against thrips
Appearance: Mobile stages: beige-pink, droplet shaped, 'pushed down' position on short legs Eggs: oblong, transparant white All stages can be found in the corner of main vein and lateral veins and in the flowers. It is not possible to distinguish Amblyseius swirskii in the field from Amblyseius cucumeris and Amblyseius californicus. Effect/Activity: Adult predatory mites search for their prey or wait for it to pass by, then suck it dry. Conditions: The predatory mite Amblyseius swirskii is: not susceptible to diapause, so can be introduced in winter tolerant to high temperature A. swirskii population starts to develop when daytemperature regularly exceeds 20-22°C Biology: Amblyseius swirskii can also develop on pollen of sweet pepper and aubergine apply preventive introduction on pollen only from the moment when crop flowers continuously Application: SWIRSKI-MITE (PLUS) can be used successfully in interior landscapes, botanical gardens, zoo's, research greenhouses and ornamental plants. |

Neoseiulus cucumerispredatory mite against thrips
Appearance: Adult Neoseiulus cucumeris are beige-pink in color and have short legs. Their body is pear-shaped and slightly flattened. They are about 0.4 mm. They are hardly visible in the crop. The nymphs are pale brown in color. They are very moving corpse as the adults. The eggs are translucent white. Thrips, Neoseiulus which sucked, are difficult to observ Effect/Activity: Predatory mites pierce their prey and suck it dry. Besides thrips eat pollen and mites N. cucumeris also, including spider mites. This is important because it enables the mites themselves in the absence of thrips larvae to maintain plants in the greenhouse and also multiply. A. cucumeris up especially thrips larvae in the first stage. N. cucumeris can be used preventively. Conditions: When humidity is below 60% dry up all the eggs. The temperature should be regularly above 20 ° C and released must not exceed 35 º C.. The minimum development temperature is 8 ° C. A. cucumeris does not go into hibernation and can also be applied to short days. Biology: The development from egg to adult mite takes 8-9 days at 25 º C. A predatory mite must mate to have offspring. The first 2 days after egg laying adult. A female lays eggs in her lifetime about 2 per day. A predatory mite lives for about 20 days. The predatory mite is about 6 at 25 ° C in the first stage thrips larvae are eaten. Application: THRIPEX can be used successfully in interior landscapes, botanical gardens, zoo's, research greenhouses and ornamental plants. |

Orius spp. roofwants tegen trips
Appearance: Adult Orius predatory bugs are brown to black with lighter patches on the wings. Males and females look alike. Just when nymphs hatch, they are almost colorless, soon they will be yellow to orange or brown. Almost all nymphal stages have red eyes. Depending on the size of the species varies from 1.5 to 3 mm. Thrips are sucked dry and there is a skin on. It is difficult to observe. Effect/Activity: All stages of Orius and thrips can kill mites. These are punctured and drained. At high densities, more prey than are slain for food is needed. At the moment, Orius laevigatus most commonly used for biological control of thrips. This species does not go into diapause. O. majusculus is a native species that are going into diapause and can be used from mid-March. This species also eats aphids except trips. Conditions: The optimal temperature for Orius is between 20 º C and 30 ° C. At a constant temperature of 11 ° C is no development taking place. A somewhat higher humidity (60%) is desirable Biology: In Orius are seven stages of development, the egg stage, five nymphal stages and adult stage. Eggs are laid in plant tissue. The development from egg to adult takes assassin at 25 º C 18 days. A thrips Orius female eats about 12 a day and puts about 150 eggs at this temperature. Adult assassin bugs live three to four weeks. Application: THRIPOR can be used successfully in interior landscapes, botanical gardens, zoo's, research greenhouses and ornamental plants. |
