Methods and platforms are provided for maintaining a population of natural enemies on plants, prior and/or parallel to an occurrence of respective prey pests, by associating with the plants platform(s) comprising mechanical support(s) with attached feeding elements for the natural enemies. The platform may be configured to keep the feeding elements close to but not on the plants, protecting them and enhancing the distribution efficiency and life time, while maintaining good availability of the feeding elements to the natural enemies. Various features may enhance supporting the natural enemies' population prior and/or parallel to the occurrence of the pest prey such as olfactory and/or visual cues to the feeding elements as well as sheltering elements such as artificial domatia on the surface of the mechanical support—to enhance biological pest control. Moreover, methods for preparing decapsulated Artemia cysts as feed for predatory arthropods are provided.

A system controls the air climate in an insect rearing climate housing. The system has an insect rearing climate housing with clusters of one or more stacks of crates with insects. The crates have at least two ventilation openings associated with each crate. An aeration system has an air control unit with a database having a reference table with conditioned air properties in relation to input parameter(s). Aeration devices are connected to the air control unit adjacent to each stack of crates, and have a plurality of exit openings that provide airstreams over the insects. The method retrieves input parameter(s) for the air control unit per cluster of crates, the air control unit determines appropriate conditioned air properties of the airstreams based on the retrieved input parameter(s), and for each individual cluster of crates separately, the air control unit sets the determined conditioned air properties of the airstreams.

An oviposition tray for ovipositioning of insect eggs, such as eggs of adult female black soldier flies, comprises a plastics oviposition tray body in the form of a planar block having a front and rear sides. The front side has a flat face defining a plurality of spaced, parallel, elongate egg laying recesses. Each recess has a length of between 8 mm and 25 mm, optimally approximately 17 mm, a width of between 1 mm and 6 mm, optimally approximately 2 mm, and a depth of not less than 2 mm. The oviposition tray body defines a number of ventilation apertures allowing for an airborne attractant to flow through the oviposition tray body for attracting insects to the oviposition try body to lay eggs. The oviposition tray body includes four spacers for spacing the oviposition tray body from other similar oviposition tray bodies in a stacked configuration of the oviposition tray bodies.

A storage and release mechanism for aerial distribution and release of insects from an unmanned aerial vehicle, the release being aimed at controlling a wild insect population, the wild population having fluctuating local densities, the mechanism comprising a switch for switching between two or more different sustainable insect delivery rates for release of the insects. The method is particularly suitable for sterile male mosquitoes in programs to control wild mosquito populations.
