  By Jasti Sri Vishnu Murthy, N.S. Satpute, Mani Chellappan, Ranjith M.T

  Abstract: Trichogrammatoidea bactrae Nagaraja (Hymenoptera: Trichogrammatoidea) is a highly effective egg parasitoid for controlling lepidopteran pests. This study evaluates its host suitability and biological characteristics across various lepidopteran eggs, specifically Corcyra cephalonica Stainton (Lepidoptera: Pyralidae), Spodoptera litura Fabricius (Lepidoptera: Noctuidae), Helicoverpa armigera Hubner (Lepidoptera: Noctuidae), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), and Pectinophora gossypiella Saunders (Lepidoptera: Gelechiidae). The results indicate that T. bactrae shows the highest parasitization rates on C. cephalonica, …

  Didymophyes bayaramae sp.nov., a new septate gregarine (Protozoa: Apicomplexa) from Aphis fabae of Manipur

  By Loukrakpam Bina Chanu, Indira Yumnam, Naorem Mohilal

  Abstract: The protozoa septate gregarines infect the midgut of Aphis fabae and cause severe infection to the intestinal tissues of the host. During a biodiversity survey on the septate gregarines parasite by the Aphud groups, we collected specimens of Aphis fabae from a bean farm in Imphal, Manipur, India. We dissected the host and isolated some protozoan parasites from the host's midgut. We encountered a new species of septate gregarine, Didymophyses …
