Description Tetrastichus howardi was identified as a hyperparasitoid of the tachinids Goniophthalmus halli and Senometopia illota, both parasitoids of Helicoverpa armigera pupae, in pigeon pea fields in southern India. Fifty-nine percent of G. halli and S. illota pupae were parasitized by T. howardi, resulting in a hyperparasitism rate of 1.9%. Unlike previous studies, T. howardi was not recorded as a primary parasitoid of H. armigera pupae. Rather than behaving as a pupal guild parasitoid, the data suggest that T. howardi oviposit in the larval stage of tachinid parasitoids while they are developing inside H. armigera pupae. The fact that T. howardi was not a primary parasitoid of H. armigera pupae suggests that this species is able to distinguish between parasitised and unparasitized H. armigera pupae.
