Beneficial insects

Colkim’s bio-factory, BIO-FAB, was created for the mass breeding of beneficial insects. These are used in biological control programmes to reduce pest populations by exploiting the phenomena of natural antagonism between species.

Habrobracon Hebetor

Ectoparasitoid antagonist of several lepidopteran species. The female H. Hebetor paralyses the larvae of food moths by injecting an insecticidal toxin and lays her eggs, thus parasitising the host.

Tricogramma Evanescens

Entomoparasitoid antagonist of several lepidopteran species. The female of T. Evanescens parasitises moth eggs by laying her own inside them. The Trichogramma egg feeds on the host until it disappears completely.

MusciTex

Nasonia and Muscidifurax species are larval-pupal parasitoids whose reproduction hinders the fly’s life cycle. The pupa of the fly is parasitised and does not complete its life cycle: the adult useful insect emerges from it.

Useful insects in biological control

Integrated biological control is a safe, sustainable and non-harmful strategy for pest control. Biological control applied to food farms involves the use of beneficial insects by the inoculative method. This consists of the periodic release of biological control agent organisms in the area to be controlled, which is necessary if the species is not present and/or scarce in the area to be controlled.

In BIO-FAB, Italy’s first biofactory in the pest control industry, we have bred the beneficial insects H. hebetor and T. evanescens for the control of food pests.

Biological lot against flies in animal husbandry

Pest control on livestock farms is related to animal welfare: a high number of flies on the farm causes stress to farmed animals with risk of disease and a decrease in milk production. Biological control for fly control involves releasing into different substrates a combination of beneficial insects (Nasonia spp. – Muscidifurax spp.), small hymenoptera that interrupt the reproductive cycle of flies by parasitizing the pupae.
