This greenhouse utilizes sticky traps equipped alongside their irrigation booms, resulting in a clever, dual-purpose IPM technique used primarily in greenhouse farming. As the automated watering boom travels along its rails over the crops, the attached sticky cards serve two major functions simultaneously: mass pest trapping and labor saved!

◇ Disturbance-Based Trapping: Many greenhouse pests (like thrips, whiteflies, fungus gnats, and shore flies) rest on the upper foliage. The physical movement of the boom and the slight air disturbance or water coming down scares the insects into flight. Once airborne, they are immediately drawn to and trapped by the passing cards.

◇ Because the boom is already automated to run on a schedule, you collect pest data and suppress populations across the entire facility without manually walking the aisles to check individual traps.

◇ Uniform Scouting: Instead of hanging stationary cards that only monitor a fixed radius, attaching a long sticky strip or a sequence of cards to the irrigation boom allows you to sample the insect population across the entire length of the greenhouse bay.

Did you know- Persimilis are one of the only biocontrol agents regularly released after their target pest is detected in the crop, as opposed to preventively, in advance?

While most beneficial insects need to be released early in the season to establish a population before pests arrive, Persimilis operates differently due to its unique biological traits:

🍬 Special diet: Persimilis feeds exclusively on two-spotted spider mites and cannot survive other insects, so it goes after them expeditiously!

⛷️ They reproduce much faster than the spider mites themselves and reproduce rapidly after finding a pest colony.

🧑‍🤝‍🧑 Adults and nymphs are both hunters, patrolling undersides of leaves and near mite colonies.

💡Help them to help you! Try to knock down the spider mite pest population first with a safe, compatible insecticidal soap or oil before releasing persimilis, or wipe webbing away so they can easily attack at the source. 🧼

Persimilis' instinct is to run straight up, so it is ideal to release them near the base of where spider mites' populations are being detected. Leave the bottle or vial in the treatment area for 24 hours after release to ensure all mites haves exited!

It is important to prioritize getting persimilis out the same day it is received since these mites are not shipped with food. Remove persimilis from the ice that they are being shipped on and leave to acclimate out of direct light in room temperature for 2 hours.

Dalotia coriaria (Atheta) are predatory rove beetles that are fast runners and active fliers, able to rapidly scour many types of media and soil!

These are aggressive generalists that feed on many soil pests, eggs, and pupae including: fungus gnat larvae, shore fly eggs and adults, thrips pupae, springtails, root mealybugs, and moth flies.

When quality testing, scatter a small sample of beetles and carrier on white paper. Beetles should be active and visible. Adults are dark brown to shiny black, 3-4 mm long and are completely covered with hair. Immature larvae change from white to orange brown.

Apply bulk Dalotia as small piles (carrier is peat/coir/vermiculite or peat/coir with no vermiculite), with 25-50 rove beetles in each pile, distributed throughout the greenhouse on potting media or on the floor.

Keep piles moist but not wet. Bulk release application is 25-50 beetles per 100 sq ft for low pest pressure; increase to 100 beetles per 100 sq.ft for moderate pressure. Release late in the day.

Breeder boxes can be created for the greenhouses using Styrofoam boxes with holes drilled in sides. Beetles are added to the box containing moist peat along with a handful of trout pellets or other protein source, and the lid is secured. The trout pellets should provide adequate protein for about four weeks, after which a new handful would need to be added every two weeks!

Growers Beware you're in for a scare!
Aphids and other sucking insects can distort leaves just by their feeding, so don't always assume the presence of a virus only by seeing signs of distorted leaves and insects, without ID'ing them properly! 🔎

Aphids, mealybugs and other sucking insects can distort leaves: the leaves are unable to expand properly as the sap is being sucked from them, and this distorts the leaf. This distorted growth may be mistaken as herbicide injury, or other leaf curl viruses, so be sure to keep records, notes and photos when you walk through the greenhouses! 📝

Some aphids are very important vectors of plant viruses. However, it is seldom possible to control these diseases by attempting to kill the aphid vectors with an insecticide. Aphids carrying viruses on their mouthparts may have to probe for only a few seconds or minutes before the plant is infected! 🧟‍♂️

Resistant varieties or sequential plantings may be helpful in reducing problems with some viruses that attack annual plants.

Aphid mummies shown above are killed by Aphidius wasps >> the wasp turns an aphid pest's body into a mummy, cutting a hole from the inside out, then emerging from the exit hole in search for more pests!

Action thresholds or Damage thresholds are not one size fits all! These thresholds can be difficult to correlate with pests, as the level will differ between type of crop, type of pest, stage of plant growth, and environmental conditions to name a few 📊

A few pests on a hardy vegetative crop may be tolerable enough to leave alone, as is, while the same number of that pest on a flowering ornamental, or fruit crop, could cause unacceptable damage and cannot be ignored! 🫯

📍Pest location, natural enemy activity, rate of population increase, and the value or the sensitivity of the cash crop can also impact the decision on what IPM tactics to use. Action thresholds are best treated as a starting point for decision-making, not a universal or definitive plan!

Good IPM means looking at the whole situation and pivoting depending on the data, not simply counting the bugs that are identified! 📌

Temperature and humidity is fundamental for roses and many other flower crops; these parameters will dictate the overall performance of biocontrols, biopesticides and some chemicals.

Unheated greenhouses often present problems with humidity, as they cool very rapidly after sunset, which may be hard to notice if growers are only working during daylight hours!

🕸 Exclusion of pests via insect netting can massively reduce the pest pressure by preventing insects entering the greenhouse e.g. thrips, whiteflies, aphids.

🕸 However, using extemely fine mesh or netting also reduces air movement, which can result in poor climate control. These pros and cons are worth weighing at this time of year, before cleaning up and sanitizing for the next spring season!

There are other types of vestibules to slow down pests that are hanging right outside the main greenhouse entrances:

🚪 Constructing double-doors with netting or plastic can be a low-cost compromise that you can advise to exclude pests if netting vents is not practical too.

Talking about climate, weather, and what influences the specific crop type, region, and seasonal situation is a great way to learn from our partners and vice versa!

Inevitably, many variables affect the successes of IPM. We are dealing with complex interactions between environment, plant, pest, beneficial organisms, chemicals and people. Monitoring, recording, and taking proper timed actions can help us get to the "root" of the problem!

Releasing Orius (Minute pirate bugs) at sundown on the day of delivery keeps these strong-flying predators in the crop canopy through their first night! 🌇

🔃 Gently rotate or roll the shipping bottle gently end-over-end to spread the bugs evenly through the carrier material (such as buckwheat hulls or vermiculite).

🧂 Open the bottle over the plant canopy, and gently tap out the carrier material and insects directly onto the leaves! Or place into Universal Release Boxes to let them disperse by themselves on one stem.

💡 Concentrate larger groups on or near plants with heavy thrips pressure, or distribute evenly for widespread populations.

🌱🤏 Wedge the open bottle into the branches or stems of a target plant so any remaining bugs can crawl out overnight, then avoid top-watering, overhead irrigation, or applying pesticides for a few days after release.

❄️ Watch out for extreme cold shipments; let them recover for a while!❄️

Sometimes, predatory insect and mite populations decline after their main source of food they predate on disappears! To combat this, we make some supplemental food sources to keep the bios comfortable in the protected crop.

NUTRIforce™ is Ephestia kuehniella sterilized frozen moth eggs used to feed beneficial insects such as minute pirate bugs (Orius), Green lacewing larvae (CHRYSOforce™), and Dicyphus.

To strike a balance between too many and too 'few" pests, it takes a focused IPM specialist to help prevent biological control "crashes"! Once the pest has been positively identified, we determine:

1. Which predators / predatory mites / parasitoids are best for the crop ➡️🌹

2. Which part of the pest life cycle should be targeted, and

3. The biocontrol rate, ratio, and method of distribution 📋

The Predatory gall midge Feltiella 𝘢𝘤𝘢𝘳𝘪𝘴𝘶𝘨𝘢 is one of the most effective and widespread natural enemies or spider mites (Tetranychidae ) because of their flying skills, prey-detecting capabilities, and high feeding potential 🕷🍴

Feltiella are known to feed on other pest mites such as brown almond mite, carmine spider mite, and European red mite.

Feltiella along with Phytoseiulus persimilis, Neoseiulus californicus, Amblyseius swirskii--are all important predators for spider mite eggs and nymphs, a decision which depends on pest pressure, type of crop, and season!
