Pathogenic Protozoans of Grasshopper from Imphal, Manipur, India

Septate gregarines or Cephaline gregarines are a group of parasitic protozoans of Grasshopper. Eugregarines are the most common; these species inhabit the midgut though rarely pathogenic in the mid-gut, they have been reported to block the gut of the host. Those inhabiting the gastric caeca cause serious pathologies than the midgut-inhabiting species. Some of the best known genera found in Manipur are Gregarina, Phleobum, Didymophyes, Amphiplatyspora, Lepismatophila, Quadruspinospora and Quadruknobspora. The study reports the morphological details of 16species of the above genera collected from Imphal. Illustrative diagrams and photomicrographs are provided for better species identification

Redescription of Lepismatophila cruszi Kundu and Haldar, 1984 (Apicomplexa : Sporozoea) from Chondracis rosea (Order: Orthoptera)

This study describes external characteristics and life history of a species of cephaline gregarine (Apicomplexa: Sporozoea) of the genus Lepismatophila [1], from Chondracis rosea (Order: Orthoptera)of Manipur, India. Diagnosis characteristic of the species the epimerite a simple symmetrical knob, Protomerite present throughout trophozoite stage, Solitary nature of Sporadins, Cyst without ducts dehiscence by simple rupture and Spores in uncoiling chains, ellipsoidal, boat shaped, without any filamentous process are discussed. And the morphological details of the different stages supported with photomicrographs are also provided

First Report of Amphiplatyspora striata Kundu and Haldar, 1984 from Chondracisrosea (Order: Orthoptera) of Manipur, India.

The present communication deals with the complete life history of a Septate Gregarine (Protozoa:Sporozoa) found in Grasshoppers. Gregarines found in the mid-gut region of Grasshoppers were collected and examined for parasites. A species belonging to the genus Amphiplatysporawas obtained from Chondracisrosea. The morphology of the gregarine and its affinities with the other genera of the family Amphiplatysporidae [3] are discussed. The morphological details of the different stages supported with photomicrographs are also provided
