Life histories of three new coccidian parasites from three coleopteran stored-grain pests of India.
TL;DR: Life histories of three new coccidian parasites obtained from the larvae of three different coleopteran stored-grain pests, Tribolium castaneum Herbst, Alphitobius piceus Olivier and Palorus ratzeburgii Wissmann, respectively, have been described in detail.
Abstract: Summary. Life histories of three new coccidian parasites (Protozoa: Apicomplexa: Coccidia) obtained from the larvae of three different coleopteran stored-grain pests, Tribolium castaneum Herbst, Alphitobius piceus Olivier and Palorus ratzeburgii Wissmann, respectively, have been described in detail. These coccidian parasites belong to the genus Adelina Hesse 1911 and are named as Adelina castana sp. n., Adelina picei sp. n. and Adelina palori sp. n. The complete life histories of these parasites are observed on the fat bodies along with the body fluid of the hosts. A comprehensive comparative account of three life histories is presented in tabular form.

TL;DR: Berto et al. as mentioned in this paper reviewed the genera Adelea, Adelina and Barroussia and found that the most common species belong to the generi cational coccidia found in the feces of carnivorous and omnivorous vertebrates.
Abstract: . Berto B.P., Lopes B. do B., Teixeira Filho W.L., Flausino W. & Lopes C.W.G. [Invertebrates coccidia associated to vertebrates food habit: A brief review of the genera Adelea, Adelina and Barroussia]. Coccidios de invertebrados associados ao habito alimentar de vertebrados: uma breve revisao dos generos Adelea, Adelina e Barroussia. Revista Brasileira de Medicina Veterinaria, 32(1):33-41, 2010. Curso de Pos-Graduacao em Ciencias Veterinarias, Universidade Federal Rural do Rio de Janeiro, BR-465 km 07, Seropedica, RJ 23890-000, Brasil. E-mail: bertobp@ufrrj.br Similar to the vertebrates, the invertebrates can be parasitized by coccidia. The most common species belong to the genera Adelea, Adelina and Barroussia, which use advantage of the alimentary habit of some vertebrates for feeding on invertebrate hosts with the purpose to assure their dispersion in the environment. Being thus, these invertebrate coccidia, considered as pseudoparasites of vertebrates, they acquired infection when they fed on vertebrates’ fecal debris containing sporulated oocysts. This habit can be responsible for innumerous erroneous descriptions of new genera and species of coccidia found in the feces of carnivorous and omnivorous vertebrates.

TL;DR: The present study has documented, for the first time in Egypt, the natural occurrence of four entomopathogenic protozoans (EPP) among five of the most abundant and damaging insect pests of stored grains or their products.
Abstract: The present study has documented, for the first time in Egypt, the natural occurrence of four entomopathogenic protozoans (EPP) among five of the most abundant and damaging insect pests of stored grains or their products. These insect pests (Laemophloeus (Cryptolestes) turcicus (Grouvelle), Rhyzopertha dominica (Fabricius), Sitophilus zeamais (Motschulsky), Tribolium castaneum (Herbst), and Plodia interpunctella (Hobner) were infesting lots of crushed-maize grains, wheat grains, and wheat flour, brought, in 2015, from El-Behera Governorate, Egypt. The morphological characteristics, including spore size, of the entomopathogen infective units, spores, of the isolated entomopathogenic protozoans, were closely fit with the description to the following genera: Mattesia, Farinocystis, Adelina, and Nosema. The prevalence of these entomopathogens ranged between 9 and 89%. This study seems to be the first report of Mattesia sp. on S. zeamais; Adelina sp. on L. turcicus or R. dominica, and the second report of Nosema sp. on R. dominica. The rate of natural infection by the neogregarine, Mattesia sp. (tentatively, M. dispora), was the highest in L. turcicus beetles (89%) followed by that in P. interpunctella moths (48%), larvae (40%), and pupae (32%) and then in S. zeamais weevils (42%) and R. dominica beetles with a low rate of infection (9%). The microsporidian entomopathogen, Nosema sp., (tentatively, N. whitei) was naturally occurred in 11% of the examined adult cadavers of R. dominica. The coccidian entomopathogen, Adelina sp., was found, respectively, in 60% and 27% of larval and adult cadavers of T.castaneum, while the Adelina-natural infection rates in R. dominica and L. turcicus adult cadavers were 34% and 14%, respectively. A high rate of natural infection with another neogregarine, Farinocystis sp. (tentatively, F. tribolii), has also been recorded in T. castaneum adult (50%) or larval cadavers (36%).

TL;DR: This supplement brings together the contents and authors indexes of Acta Protozoologica throughout the 40 volumes that have been published since 1963 and believes that this Cumulative Indexes will be an important contribution to the field of protistology and a useful tool for retrieving suitable references.
Abstract: This supplement brings together the contents and authors indexes of Acta Protozoologica throughout the 40 volumes that have been published since 1963. The journal gradually became established through the support of a number famous scientists who used it to publish their original articles and reviews. With the publication of our 40-th volume, we are indebted to the famous Polish scientists, Professor Zdzislaw Raabe from the Warsaw University, and Professor Stanislaw Dryl from the Nencki Institute of Experimental Biology, Polish Academy of Sciences, for their efforts and initiative in establishing the international journal Acta Protozoologica in 1963. We believe that this Cumulative Indexes will be an important contribution to the field of protistology and a useful tool for retrieving suitable references.

Departamento de Biologia Animal, Instituto de Biologia, Universidade Federal Rural do Rio de Janeiro. BR-465 km 7, 23897-970 Seropedica, RJ, Brasil. E-mail: bertobp@ufrrj.br The insectivorous habit of some vertebrates is essential for the life cycle of some coccidia of invertebrates because they depend of the feeding habits of vertebrates which ingest invertebrate hosts to ensure that the adeleid oocysts will be dispersed. This study reports adeleid polysporocystic oocysts from feces of the frog Thoropa miliaris Spix in Marambaia Island, State of Rio de Janeiro, Brazil. This sporulated oocysts belong to the genus Adelina, which was parasitizing an invertebrate ingested by T. miliaris. The oocysts were ellipsoidal, 37.6 × 31.4 μm, with a smooth, bilayered wall. Micropyle, oocyst residuum and polar granule were absent. The number of sporocysts per oocyst varied from 14 to 21. The sporocysts were subspherical, 9.1 × 8.5 μm. Stieda and substieda bodies absent. Sporocyst residuum composed of scattered granules. Sporozoites present subspherical refractile bodies at both ends. This is the first report of a pseudoparasite in amphibians. Comparative morphology of 29 Adelina spp. is presented in tabulated data.

TL;DR: The coccidian dealt with in this paper is a parasite of the blood, fat bodies and connective tissue of Tribolium ferrugineum as mentioned in this paper, which is a species of caterpillar.
Abstract: The coccidian dealt with in this paper is a parasite of the blood, fat bodies and connective tissue of Tribolium ferrugineum. W. A. Riley and L. Krogh were the first and perhaps the only ones who noticed stages of this parasite, when studying the histology of the larvae of this beetle. They found the pupae and adults uninfected, but in the course of the present work some of them were heavily infected, though only a small number could be examined.

TL;DR: The coccidian from the black beetle, Heteronychus arator (Fabricius), in New Zealand was identified as Adelina tenebrionis Sautet 1930, and electron micrographs of merozoites and gametocytes are presented.
Abstract: The coccidian from the black beetle, Heteronychus arator (Fabricius), in New Zealand was identified as Adelina tenebrionis Sautet 1930. Its development occurs in the fat body of the host. Merogony produces bundles of 8–19 vermiform merozoites, which range in length from 12.0 to 24.1 Μm. Spherical macrogametocytes and small, vermiform microgametocytes fuse to form a zygote. Sporogony produces an oocyst 29.2–45.0 Μm in diameter, containing 3–13 sporocysts, 12.3–14.0 Μm in diameter. The life cycle takes about 46 days in an alternative host, Planotortrix excessana (Lepidoptera: Tortricidae), at 22‡ C. Electron micrographs of merozoites and gametocytes are presented.

TL;DR: Artificial infection experiments were carried out and material was furnished for determination of succession of stages in the life cycle of the organism, finding evidence that both male and female gametoblasts are formed from a single schizont.
Abstract: 1. The occurrence of Adelina cryptocerci in the host, Cryptocercus punctulatus , and its probable means of natural transmission are discussed. 2. Artificial infection experiments were carried out and furnished material for determination of succession of stages in the life cycle of the organism. The cycle is briefly as follows: ( a ) Mature cysts are ingested by the hosts with tissues of infected roaches. Sporozoites enter the host's tissues by passing through the midgut wall. ( b ) The first schizogony, in which merozoites are produced, ocurs in the fat-bodies between the sixteenth and twenty-fifth days after ingestion of cysts. ( c ) In the second schizogonial generation two types of schizogony produce merozoites and gametoblasts, respectively, between the twenty-fifth and twenty-ninth days following infection. There is evidence that both male and female gametoblasts are formed from a single schizont. ( d ) Male and female gametoblasts become associated during the growth period of the latter. When fully grown, they are surrounded by a membrane, the gametocyst. The male gametoblast undergoes 2 divisions, forming 4 microgametes, of which 1 fertilizes the macrogamete and the other 3 lie unused between the gametocyst and the first oocyst, which is formed shortly after fertilization. A second oocyst is formed before the first division of the synkaryon. ( e ) By repeated divisions of the synkaryon a multinucleate sporont is formed. This divides into uninucleate sporoblasts. Each sporoblast divides once, forming a sporocyst containing 2 sporozoites. Mature cysts occurred in experimentally infected roaches from 40 days onwards. 3. The stages in the life cycle are described in detail. 4. Evidence for zygotic meiosis in Adelina cryptocerci is presented. 5. The effect of the parasite on the host is discussed. This investigation has been made at the suggestion of Dr Harold Kirby, Jr., and under his direction and that of Dr C. A. Kofoid. I wish to express here my grateful appreciation to both for their interest and many valuable suggestions and criticisms.
