Mosquito Larvae Trays. Standardised larval rearing units for insect production are essential for the establishment of insect mass-rearing facilities. We offer water-filled mosquito rearing trays according to the specifications by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture (FAO/IAEA-IPCL; Balestrino et al., 2012). The trays are compatible with the Mosquito Mass Rearing Tray & Racks / modules; each holds 30 mosquito rearing trays (50x in the XL version). The mosquito trays are optimized to work with the automatic larvae feeder.
According to research, the mosquito tray is applicable for rearing larvae of several mosquito species. For Aedes albopictus, for example, the optimal larval rearing density in the water-filled trays is about 18,000 larvae (3.6 larvae cm-2 inner surface). At thirty-four hours after the first pupation, the average male pupae production was found to be ca. 3.16 × 105; no impact on male mating competitiveness to wild type females was found and the tray was recommended to be used in mosquito mass rearing facilities (see Zhang et al., 2017 for details). Regarding Anopheles sp., each trays can hold about 4,000 larvae (Mamai et al., 2018). The use of the trays for rearing other insect species requiring similar environmental conditions for pupation is likely but can also be adjusted on request.

Mosquito Tray (IR-MMR-Tray) specifications are based on Balestrino et al. (2012) & technical requirements of IAEA/FAO Insect Unit (Seibersdorf, AT).
ABS has been approved by the IAEA insect laboratory as a suitable material for the mosquito trays, while fiberglass and metal trays are not currently considered.
Add the recommended, species-specific number of L1 larvae to each tray. Prepare the eggs/larvae either in batches or in larger containers and take aliquots; it is a good practice to determine the hatch rate on subsamples before calculating the final number of collected mosquito eggs to be reared for each tray.
To ensure consistent and reliable pupae development, larvae should be reared under controlled and stable environmental conditions (temperature, humidity and (partially) photoperiod). Therefore, Aedes larvae mass rearing trays, for example, should be placed in a climate-controlled room at a temperature of 28±1ºC and a relative humidity of 70-80%. Establishing an illumination schedule that mimics the day/night cycle will help synchronize larval pupation and emergence regardless of the season. Synchronized pupation is a key requirement for the cost-effective use of mass rearing trach & rack systems for both mosquitoes and mealworm farming.
Overall, a very large diversity of larval mass rearing trays sizes, shapes and forms exist. However, trays are an essential tools for efficient and effective mass rearing of insects and their design must be tailored to the specific needs of the insect species life stage and the intended application. Vienna Scientific is happy to support this process and help you realize optimized trays for the insect species of choice - contact us!
