Description and Biology

Dalotia coriaria are slender black/brown beetles, each about 3-4 mm long, known for their agility and rapid movement in soil. Both adult beetles and larvae are formidable predators, feeding on a variety of small insects and mites, making them particularly effective against fungus gnats and shore flies. They thrive in environments above 65% relative humidity, although their eggs can survive down to 40% RH. The beetles have a short development time, maturing from egg to adult in about three weeks at optimal temperatures (25°C), and can consume up to 150 fungus gnat eggs per day.

Suitable Crops and Environment

Dalotia coriaria is highly adaptable and can be used in a range of environments, from indoor greenhouses to outdoor crops. They perform exceptionally well in nurseries and are commonly used in cannabis cultivation, as well as in a variety of vegetables and ornamental plants. These beetles prefer warm, humid conditions for optimal development and are particularly suited to environments where the growing medium might become waterlogged.

Release Instructions

Dalotia should be released as soon as possible upon delivery. For preventative measures, distribute 2-5 beetles per square meter, repeated bi-weekly. For curative treatments, especially in hotspots, release rates can be increased to 10 beetles per square meter weekly until control is achieved. The beetles should be distributed directly onto the surface of the growing medium or at the base of plants for effective integration.

Monitoring and Maintenance

After release, monitoring Dalotia populations can be challenging due to their quick dispersal and integration into the growing medium. Adults might be spotted on the soil surface or caught in yellow sticky traps, while larvae can be detected with a simple potato slice test. It's recommended to maintain cultural practices that support their establishment and effectiveness, such as ensuring the growing medium is not overly saturated.

Chemical Sensitivity

Dalotia are sensitive to many pesticides, particularly pyrethroids, organophosphates, and neonicotinoids. It’s crucial to avoid these chemicals as they can severely impact the beetles' survival and efficacy. Always opt for pesticides that are least harmful to beneficial insects to support a successful integrated pest management (IPM) program.

By integrating Dalotia coriaria into your pest management strategy, you're choosing a natural, sustainable method to protect your crops, enhancing the health and productivity of your garden or farm without the reliance on harsh chemicals.
