Our Biological Control System

Unlike most greenhouses that use chemical-based pesticides, we pride ourselves on using biological control insects. In our greenhouse, we release specific, natural, insects throughout our seasons, that are meant to protect our crop, by eating plant-eating insects. These beneficial insects (Beneficials as we call them) help our plants grow full and healthy, without compromising on quality. We stay away from chemical pesticides because we know that once our product is at your home, the chemicals can run off and harm other plants.

Check out some of the beneficial insects we use below!

Aphid Control

 

Aphids are one of them most aggressive pests we have. In winter months they are male and female but in the summer months they are typically female (Some months sexual some months asexual). They are born pregnant and give birth to live young. They live 20-40 days depending of temperatures. They can produce billions of offspring in one growing season if not kept in check.

Aphidius colemani- These miniature wasps lay their eggs inside of the aphid and when they are ready to hatch they carve a hole in the back of the aphids to emerge from.

Aphidoletes aphidmyza- These orange larvae feed on aphids by sucking their bodies dry. Only the larvae attack aphids the adults do not.

Chrysoperla Carnea - These are one of the only curative insects we release. They are great to release when you are starting to have a population become a little higher. They also suck the bodily fluids from their prey. Chrysoperla will also feed on Thrips and Whitefly.

Thrips Control

 

Thrips lay their eggs inside of the plant tissue making it extremely difficult to find them. When they hatch their larvae fall into the soil to pupate. We release Neoseiulus cucumeris, Stratiolaelaps scimitus and Dalotia coriaria to control Thrips larvae. All three of these beneficial insects control a different life stage of the Thrips larvae. They are one of the hardest insects to control chemically. They can fit their small bodies inside of flower buds making it impossible to reach them with sprays. Orius Insidiosus can also get into the flower buds and have controlled our Thrips population better than chemicals ever have.

Orius Insidiosus- This true bug is the only insect that feeds on adult thrips! I is considered a generalist predator and will eat aphids and moth eggs as well but only when its preferred food source is low.

Neoseiulus Cucumeris- This is a tiny mite that feeds on thrips, fungus gnat and shorefly larvae- they feed on the hatching eggs and first larval stage. These are the mites inside of the sachets in each hanging basket.

A Few Others

Rove Beetle

Rove Beetles are good for controling Fungas Knats in our greenhouse. Both the larve and adult beetles, feed off of these knats and are one of our primary knat control insects

 

The Lacewing Larave is another Aphid control insect that we release. In the picture above, you can see a Lacewing just above an Aphid.
