Parasites of the pigeonpea podfly, Melanagromyza obtusa (Malloch), in India.
The parasitoids of Melanagromyza obtusa were surveyed in pigeon pea [Cajanus cajan] fields in India, in 1977-1983. Six genera were recorded: the eulophid Euderus, Eupelmus, the eurytomids Eurytoma and Plutarchia, the torymid Antistrophoplex and Ormyrus. There was a peak in overall parasitism in February-March, when the pest populations were also high. Euderus and Ormyrus were the dominant parasitoid genera in Andhra Pradesh and were generally widespread in India. There was a significant difference in the extent of parasitism on 2 C. cajan cultivars, ICP 1 and HY 3C, which was probably related to host abundance.
