Studying ants and their interactions with parasites over evolutionary time can advance our knowledge of the spread of disease throughout a society in general. In this research paper, I focus on worms infecting ants. The principal parasitic worms affecting ants are in the phylum Nematoda and the classes of Cestoda and Trematoda. Much of the previous research endeavors that have been completed on the study of worms infecting ants have been lost to time and language. The time and effort dedicated by other scientists to the study of this important relationship needs to be unearthed and that is what I attempted to do in this paper. Therefore I conducted a detailed library study of the diversity of worm parasite in ants, which involved extensive exploration of both the non-digitized corpus and non-English language corpus. Not only did I find more ant-worm parasite association records than previously known, but also I uncovered many significant records of parasite prevalence and distribution. My work lays the foundation for more research that can now be done on this subject. Furthermore, my work will hopefully resolve the ecological drivers of ant-parasite relationships and their evolutionary implications. ii TABLE OF CONTENTS LIST OF FIGURES ..................................................................................................... iii LIST OF TABLES ....................................................................................................... iv ACKNOWLEDGEMENTS ......................................................................................... v Introduction .................................................................................................................. 1 Materials and Methods ................................................................................................. 5 Results .......................................................................................................................... 7 Discussion .................................................................................................................... 21 Conclusion ................................................................................................................... 33 BIBLIOGRAPHY ........................................................................................................ 34 iii LIST OF FIGURES Figure 1.

According to a calculation done by Hölldobler and Wilson (1994), if there are one million trillion insects alive on earth, and if 1% of these insects are ants, and if individual workers weigh on average 1-5 mg, then the total weight of all the ants in the world is approximately equal to the total weight of all of the people in the world. While ants account for less than 2% of all insect species, they are the dominant fauna of all terrestrial ecosystems and they make up almost 70% of individual insects in tropical forests (Hölldobler and Wilson 1994). The dominance of ants in their environment leads them to be very involved in the lives and evolution of many other organisms. One relationship that has been studied extensively is the relationship between ants and their parasites. Ants can be a host to many kinds of organisms including viruses, bacteria, fungi, protozoa, flagellates, helminths, mites, Hymenoptera, and other types of insects (Schmid-Hempel 1998). Ants are of the most advanced type of social insects because they have the three biological traits that researchers use to define eusociality: the adults care for the young; two or more generations of adults live together in the same nest; and the members of each colony are divided into castes -a reproductive caste and a nonreproductive caste (Schmid-Hempel 1998). Eusociality makes ant colonies profitable targets for parasites because of the high density and high relatedness of ants in each colony (Schmid-Hempel 1998). Some of the qualities that make ant colonies profitable hosts also make them a difficult host for parasites to invade. Just as ants are diverse, so are the organisms that parasitize them. Therefore, parasites of ants use various strategies for infection. For example, parasites often target larvae and pupae as prime hosts which are often infected not by direct exposure to the parasite but through contamination of their food or nest material by other workers. 2 Bacteria and spores of fungi can remain infective for years and produce infections with few outward symptoms. A nematode infection occurs when the infective-stage nematode invades the host either by directly penetrating the cuticle or through natural openings, like the mouth, when the ant ingests an egg as food. Several rhabditidae nematodes have been reported in ants. Poinar (1975) grouped nematodes according to whether they are phoretic, facultative, or obligatory parasitic. Phoretic nematodes are not known to be associated with ants. The facultative nematodes are able to complete their life cycle outside the host. In insects they can be found in the body cavity, intestinal tract, pharyngeal and other glands or in the trachea. Obligate parasitic nematodes cannot live without a host and have no free-living stages. Generally these species are found in the insect’s body cavity; some may be found in the intestinal tract and reproductive system. A nematode’s life cycle can include intermediate hosts but they tend to have few host species. Several rhabditid nematodes have been reported from ants. Typically they parasitize the pharyngeal glands in the head of their host. Examples are Caenorhabditis dolichura (Janet 1983) in Formica fusca (Nickle and Ayre 1966), in Camponotus herculeanus and Acanthomyops claviger (Wahab 1962), and in other ants. Trematodes are a class of parasitic flatworms known as flukes. Parasitic trematodes use multihost life cycles involving two to three hosts in which molluscs serve as the first intermediate hosts and vertebrates serve as final hosts (Barger and Fellis, 2002). Krull and Mapes are credited with being the first to reveal the life cycle of a well-studied trematode, Dicrocoelium dendriticum (1952, 1953). They discovered that the adult D. dendriticum lays its eggs in the liver or bile-duct of certain mammals. The eggs are transferred to the first intermediate host, a mollusc through the feces of 3 the mammal. The infected snails produce slime balls which contain the trematode which by then has developed from eggs into cercariae. Ants are the second intermediate host and become infected because they use snail slime balls as a source of water, so they end up ingesting the cercariae with the slime. While inside of the ant, the trematodes penetrate the ant’s stomach in and enter the hemocoel. From there, they move through the ant’s body to its brain where they develop into metacercarial cycts. When the trematodes are in the ant’s brain, they can cause the ant to behave differently than normal in order to facilitate the trematode’s passage to its final host, livestock like sheep. For example, the ant will become more sluggish and lose sensitivity to light. Both of these things will cause the ant to spend more time outside the nest and therefore be more likely to be eaten by grazing livestock so that the trematode can complete its lifecycle (Carney 1967, 1969). This is just one example of how parasitism by worms can change the ant behavior. Cestodes are a class of parasitic tapeworms that are known for living in the digestive tracts of vertebrates as adults and the bodies of other species of animals as juveniles. Parasitic cestodes

The nematodes may contribute to ant mortality and collapse of colonies by transferring environmental bacteria. M. rubra ants naturally hosting nematodes were collected from collapsed wild nests in Maine and used for bacteria identication. Virulence assays were carried out to validate acquisition and vectoring of environmental bacteria to the ants. Results: Multiple bacteria species, including Paenibacillus spp., were found in the nematodes’ digestive tract. Serratia marcescens, Serratia nematodiphila, and Pseudomonas uorescens were collected from the hemolymph of nematode-infected Galleria mellonella larvae. Variability was observed in insect virulence in relation to the site origin of the nematodes. In vitro assays conrmed uptake of RFP-labeled Pseudomonas aeruginosa strain PA14 by nematodes.

    Received: 23rd May-2013 Revised: 01st June-2013 Accepted: 05th June-2013 Research article A STUDY ON THE SEASONAL PREVALENCE OF RAILLIETINA TETRAGONA IN DOMESTIC CHICK (GALLUS DOMESTICUS) FROM WARANGAL REGION OF ANDHRA PRADESH. Achaiah.N*and N.Vijaya Kumar Dept of Zoology, Kakatiya University, Warangal, A.P, India. E mail: [email protected] ABSTRACT: The prevalence of Raillietina tetragona, a helminth parasite was examined in domestic chick for a period of two annual cycles to determine the effects of seasonal variation on intensity and incidence of infection. The results show that the infection was more during summer followed by rainy and winter seasons. The infection was single or in association with other helminth parasites like Raillietina echinobothrida, Raillietina cesticillus and Ascardia galli. The results are discussed in relation to seasonal variation. The results were analysed by student t-test (P<0.05). Key words: Raillietina tetragona, domestic fowl, prevalence, seasonal variation. INTRODUCTION Parasite represents an important component of natural community (Preston and Jhonson, 2010). Parasites have a wide impact on ecology of their hosts like health (Arme and Owen 1967) and regulation of host population (Freeland, 1979) and behavior (Millinski, 1984 and Moore, 1984). Most of the families in rural areas is associated with poultry production either directly or indirectly. Chickens are allowed to move freely in and around in surrounding areas of houses in search of food, which makes them more exposed to infections (Soulsby 1982). The helminth infection in chicken has considerable economic importance as it causes reduction in growth and weight, decrease in egg production, predation and mortality (Nair and Nadakkal, 1981 and Belghyti 2006).

  • Ants Inhabiting Oak Cynipid Galls in Hungary
    North-Western Journal of Zoology 2020, vol.16 (1) - Correspondence: Notes 95 Ants inhabiting oak Cynipid galls in Hungary Oaks are known to harbour extremely rich insect communi- ties, among them more than 100 species of gall wasps (Hy- menoptera: Cynipidae) in Europe (Csóka et al. 2005, Melika 2006). Some gall wasp species are able to induce large and structurally complex galls that can sometimes be abundant on oaks, providing attractive shelters for several arthropod taxa including ant species. Ants are among the most important players in many ecosystems and they are also considered to act as ecosystem engineers (Folgarait, 1998). They are also famous for having ecological or physical interactions with a great variety of other organisms, such as gall wasps. Ants are known to tend Figure 1. Inner structure of the asexual Andricus quercustozae gall in- aphid colonies on the developing galls and, as general pred- habited by ants. ators, they prey on arthropods approaching the protected aphid colonies. Some oak cynipid galls secrete honeydew on their surface. This sweet substrate attracts ants and, in re- turn, the ants protect the galls from predators and parasi- toids (Abe, 1988, 1992; Inouye & Agrawal 2004; Nicholls, 2017). Beyond this obvious ecological interaction between gall wasps and ants, this association continues after the gall wasp’s life cycle has ceased. Certain galls are known to serve as either temporary or permanent shelter for many ant species. Some galls (e.g. An- dricus hungaricus (Hartig), Andricus quercustozae (Bosc), Aphelonyx cerricola (Giraud)) are large enough even for re- productive ant colonies. The advantages of galls as nesting logs are multifaceted.

The main purpose of factor analysis - reducing the dimension of the source data for the purpose of economical description by providing minimal loss of the initial information. The result of factor analysis is the transition from the set output variables to significantly fewer new variables - factors. Factor is interpreted as a common cause of the variability of the multiple output variables. The value of the revealed factors is 4,37 and 1.98 respectively. The selected factors include 79,5% of general dispersion (54,7 and 24,8 % respectively). Thus the accumulated percentage of both factors dispersion (79,5 %) defines how fully we can describe the set of date with the help of selected factors. The higher this index is the larger part of the data was factorized and the more credible the factorial model is. In widespread application of modeling in solving the problem of knowledge and environmental protection the combination of two tendencies which are characteristic of the modern science are singled out – cybernation and ecologization. The information systems are used to choose the optimal ways of different resources application in order to predict the consequences of environmental pollution.
