About whitefly
Whiteflies are a common pest we struggled to manage when we started our urban food forest. These insects have white wings and come from the Hemipteran family called Aleyrodidae. They feed by sucking sap from leaves and laying eggs on the underside of leaves. Whiteflies can change colour to black in shaded areas and can be a nuisance by flying into your nose and eyes.
Whitefly Host Plants
These pests are commonly found on plants in the Solanaceae or nightshade family, which includes tomatoes, potatoes, eggplants, and tamarillo plants. They can also be found on chicory, cabbage, and kale leaves. Unfortunately, these pests are particularly fond of weeds such as dandelions and amaranths. Once they become established, they are challenging to get rid of.
Effects of Whitefly Infestations
Whiteflies can cause damage to plants and affect their ability to produce crops. These insects may lay eggs on the undersides of leaves, leading to spots that remain even after the pests have been eliminated. In addition, whiteflies can transmit viruses and other diseases harmful to plants. It is essential to take preventive measures and control whitefly populations to ensure plant health and high crop yields

Whitefly Prevention and Control
There are several strategies that you can use to prevent infestations of whiteflies. Firstly, spraying new plants with Neem oil or its derivatives is a good idea. If they’re already infested, try spraying the underside of leaves with water to dislodge adult insects. Keeping your garden free of host weeds like dandelions and amaranths can also be helpful. If you have a small garden with only a few plants, you may want to consider using mineral oil to suffocate the larvae, although you should be aware that this can cause leaf damage.
Sticky traps can also be effective for controlling adult fruit flies. Make sure to place the traps in the east-to-west direction and at double the height of your crops. Other small insects like Tuta absoluta and Diamond black moths may also be caught in the traps, but using pheromone traps specific to those pests is the most effective control method.
Managing Whitefly infestations
Effectively controlling whitefly infestations over larger areas or severe infestations may require regular pesticide sprays with neem oil derivatives like nimbocidine. Organic farmers can opt for these products that are acceptable for organic farming. However, keep in mind that pests might become resistant to neem oil derivatives, making it necessary to combine them with Emamectin Benzoate compounds like Destroyer. Additionally, sticky whitefly traps can bring down the population. Introducing whitefly parasitic fungi like Beauveria bassiana can also help organic farmers. During the rainy season, take advantage of the rain to dislodge whiteflies from leaves, making them easier to control when spraying.
