Thrips Prevention - Thrips are very difficult to reach with chemical sprays but Amblyseius predator mites are small enough to find and eat them, release early as they control the larval stage.
Sold in sachets and shakers, all our prices include P&P. Orders placed by 10am Monday will be despatched later in the week.
Thrips suck juices out of leaves and emerging flowers, leaving them with a 'rasped' look. They do not generally kill plants, but make them look tired and unsightly. If they attack young emerging shoots then leaves may be crooked and misshapen.Amblyseius cucumeris is a tiny, pale coloured beneficial mite. It is used by professional glasshouse growers to control thrips and tarsonemid mites. It can be used in gardens outside in the summer months in sheltered areas and in heated glasshouses and conservatories.
These mites crawl around on the leaves and within the flower buds looking for their favourite prey which are thrips larvae. They usually target the smaller, newly hatched young, but they have been known to tackle larvae bigger than themselves. The mites also work well to prevent outbreaks of broad and cyclamen mites.
Amblyseius Cucumeris can tolerate hot, dry conditions, suitable for glasshouses and conservatories, as well as outside during the Summer.
Amblyseius spp. are difficult to spot with the naked eye, and to tell apart even with the benefit of a microscope. The colour of the mites vary according to what they have been feeding upon.
Which format to choose;
SachetsRelease a breeding colony of mites onto the plant, even before the target pest is present. The breeding colony is contained within a small paper sachet, which is carefully designed to maintain the colony in good condition. Mites continue to emerge from sachets over several weeks and in much higher numbers than with a single broadcast release.
Loose MaterialAn immediate and high dose of predatory mites. Good for quickly establishing a population of mites and providing an immediate defense for your crop.
Instructions for use
These mites need to be within crawling distance of their prey. Simply hang the sachets among the leaves away from direct sunlight and within reach of their prey. The mites crawl out of the back of the sachet through the little round hole so there is no need to make a further tear or hole.
You can prop the sachets up on the base of the plant if the plant is not big enough to support the sachet. The sachets will last longer if they are out of direct sunlight and sheltered from overhead watering. The mites will leave the sachet over the next 4 to 6 weeks so be careful not to take it away too soon.
These little predatory mites work best in temperatures between 10°C – 27°C, and appreciate some humidity to help them gain control of their prey more quickly.
For best results, introduce the Amblyseius in mid-May for frost-free conservatories, or earlier where temperatures are constantly warm. Amblyseius will survive on pollen from flowers until the young thrips start to appear and provide them with a preferred diet, thus preventing an infestation from taking hold.
The most serious type of thrips is the Western Flower Thrips. The insects are generally hidden inside flowers, but can be seen by shaking a flower onto an open hand, or by trapping them onto glue traps (blue is the best colour for thrips).
They drop to the ground to pupate, so keeping the ground or bench clean may discourage development of succeeding generations.
