Amblyseius cucumeris - Loose Predators - Thrip Curative System


Size

What Are Thrips & How Do I Identify Them?

Thrips are the smallest winged insects, and there are about six species of Thrip that cause damage to plants in greenhouses and indoor growing. Thrips have six stages in their life cycle; egg, two larval stages, pre-pupa, pupa and adult. The larvae and the adults feed on plants. The adults are tiny, dark coloured, pencil shaped insects, often found in flowers. The larvae are often found on the leaves. The Thrip pierce plants when feeding, causing plant tissue to die. This will be evidenced by silvery scratches on leaves with tiny black marks on.

What Are Amblyseius Cucucmeris Mites & How Can They Help?

Amblyseius (Neoseiulus) cucumeris is a natural predator of numerous Thrip species. The predators are packaged in a loose carrier material for instant release onto infestations. The cucumeris will consume Thrip larvae and eggs, and will continually move around the plant and flowers seeking out their prey.

The cucumeris predominantly feed on the small, or first Instar, larvae of the Western Flower Thrip (Frankiniella occidentalis). The cucumeris therefore break the Thrip life cycle by consuming the larvae and eggs before the pests can develop into adulthood. The cucumeris will also feed on flower pollen which allows for their introduction before the Thrip pests are visibly present. With predators on the plant at all times, the Thrip can be killed before they can take hold.

The cucumeris will not feed on the larger larvae or adult Thrips, however, and the application relies on breaking the Thrip life cycle. To tackle larger infestations, we would advise for an application of Amblyseius swirskii. The predatory bug, Oriuscan also be introduced to feed on adult Thrip.

Severe Thrip infestations may require more than one application of predators. Allow 7-10 days and reapply the predators if the Thrips are still visibly present. Once the infestation is controlled switch to our sachets to avoid further outbreaks.

When Should I Use Loose Cucumeris?

We advise using loose cucumeris when Thrip is already present on the plant. This immediately releases a large number of active predators to bring infestations under control. Do not apply if you have used chemical treatments in the past 2 weeks.

What Conditions Do The Cucumeris Require?

Temperatures should be between 15-30 with a relative humidity level of 70% for optimal Thrip control using cucumeris.If it is below 60% no eggs will hatch and the cucumeris population will not increase.

How Many Cucumeris Mites Do I Need?

We recommend the following application rate based on an average plant height of 1m:

- Light infestation: 200 mites per plant

- Heavy infestation: 500 mites per plant

Repeat applications may be required against heavy infestations. You should introduce fresh predators every 7-10 days until the infestation is controlled.

How Do I Apply Loose Cucumeris?

Amblyseius cucumeris are supplied in a loose bran material that can be gently sprinkled directly onto leaves or heaped onto Rockwool blocks at the base of your plants.

Cucumeriscan also be applied using our Dragonfli Distribution Boxes, which will be more effective for larger plants. Distribute the bottle contents into your boxes and hang them on the stems or leaves of your plants. The boxes act as small breeding sites for the predators before they proceed to exit the boxes and move around the plants.

Repeat applications may be required to maintain cucumeris populations, or if Thrip numbers were high when the predators were first applied.

Full application instructions are provided on delivery.

When Will I Need To Replace The Predators?

The predators will begin consuming Thrips immediately and, providing the conditions are optimal, they will continue to feed and reproduce until the infestation is controlled. If you cannot see that Thrip numbers are reducing after around 7 days, you may need to apply more predators to completely eradicate the infestation.

Can I Store The Cucumeris Predators? 

We advise using cucumeris straight away upon delivery, this ensures best results as the mites will be fresh.

Chemical Pesticides

Amblyseius cucumeris is a living creature and can be affected by any chemical pesticides used within the previous few weeks. As a general guide, refrain from using Natural Pyrethrum or SB Plant Invigorator 2 days prior to use. Other chemical insecticides can have long lasting residues that could harm cucumeris and other predatory mites for much longer periods. Refrain from using these products or check with Dragonfli for information on the effect of these products on the predatory mites.

Allergy Information 

Just as you can be allergic to cats, pollen, and dust mites, it is also possible to be allergic to the natural substances in predatory mites, feeder mites, and supplementary feeding products. If you are particularly allergy prone and concerned about the potential effects of our mites please contact your local GP prior to purchase. Please note that allergic reactions to our mites are extremely rare.

Definitely making a difference

I have had a major Thrip issue on my Dahlias for a number of years and these have definitely made a noticeable difference. I will be using them again next year, but I will apply earlier in the season (I came across them late)

There products are good , but delivery shocking , second order, first took nearly 3 weeks to come then second order got lost so then had to message for them to send out again so waited 3 weeks again

Hi Keeley,

Thanks for your feedback. Glad to hear you've been happy with the products you've ordered from us and we would like to thank you again for being a loyal customer.

There is a usual lead time on live products of up to 5 working days due to their live nature and short shelf life. These products are made to order to ensure you receive the freshest and most effective product possible. These live product lead times are mentioned under our delivery information on our website. We do offer express shipping, via DPD, which speeds up transit time from dispatch in comparison to Royal Mail and Evri shipments, but it cannot shorten the production and dispatch time. This is why we state delivery times from the dispatch day, rather than from when the order is placed.

I can see from your order history, however, that you have endured a couple of delays so please contact our customer service team and they will find a resolution for you.

Kind regards,

Julian Ives [Director, Dragonfli]

Amblyseius cucumeris

I’ve never used cany thing like this before. It was hard to tell if I was applying correctly. Also don’t don’t if it is working yet. Maybe some clearer or video instructions?
