Abstract: The applied biological control is one of the integrated pest management (IPM) tactics. Many insect parasitoid species can be mass-reared under controlled conditions, followed by field releases aiming to control specific pests. Among them, Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae) is one parasitoid that attacks pupae of different pest species, for example, the sugarcane bores Diatraea spp., the diamondback moth Plutella xylostella L. (Lepidoptera: Plutellidae), and other leaf-eating caterpillars as Oxydia vesulia Cramer (Lepidoptera: Geometridae), etc. Biological, behavioral, and production traits such as: location and parasitism capacity of concealed hosts, high number of descendants per parasitized pupa, lack of host resistance to parasitism, large-scale rearing feasibility on alternative host, and low production costs in insectaries maintaining parasitoid quality, make T. howardi a potential natural enemy candidate to be used in IPM of different crops to reduce lepidopteran pest populations. Moreover, using this parasitoid is a sustainable control strategy, an alternative to chemical control, meeting the growing market demands for agriculture products free (or with low use) of pesticides, especially in areas of organic agriculture.
