Average weight of mealworm at harvest (milligrams)Mealworms per kilogram

We've assumed an average weight at harvest of 110mg, based on available information. Modify this number to see the impact of mealworm weight on the amount of area required for farming.110The number of mealworms per kilogram at the point of harvest. This is derived from the average weight, so there's no need to change it manually.9,091

Area required per mealworm (cm²)Depth of container (cm)
16
Based on literature review, an optimal density of 2-2.55 larvae per cm² was indicated. Change this number to see how larval density will impact the number of worms produced. Note that this model does not take into account the impact of density on yield, so weight is inaccurate outside of the indicated range.0.45Assuming mealworms are housed within a tray-like container, this depth is used to calculate the volume of feed that can be placed within each. It can be varied based on the containers locally available.10

The ratio of feed input to insect mass output. Change this number to see how the cost of feeding a colony varies with the efficiency of feed conversion.2.2The cost, in dollars, of a kilogram of feed. Change this number to see the impact of feed prices on the cost of raising mealworms.$2.20
