New and Emended Descriptions of Gregarines From Flour Beetles (Tribolium Spp. And Palorus Subdepressus: Coleoptera, Tenebrionidae)

First record of gregarines (Apicomplexa) in seminal vesicle of insect

“…In this study it was reported that the gregarines enter into the intestinal cavity through ingestion, go through the intestinal wall and reach the accessory gland, where they adhere to the wall and finally are released into the gland lumen. The occurrence of intestinal gregarine has already been recorded for several insects, including the tenebrionid beetles 4, 19 , and the contamination process is known, which occurs through ingestion of oocysts during feeding 10, 20 . In the earthworm seminal vesicles the life cycle and infection process were well established and showed that the contamination occurred by an oro-fecal route, with the parasite crossing the intestinal wall to reach the dorsal vessel and the heart from where it was transported to the seminal vesicles 21 .…”

“…Among insect, Orthoptera, Odonata, Blattodea, Diptera, and Coleoptera have been reported to be infected by gregarine 1, 4, 5, 10 . The presence of these parasites is recorded especially in digestive tracts of larvae and adults, Malpighian tubules, fat bodies and eggs 10 .…”

Challenges of metamorphosis in invertebrate hosts: maintaining parasite resistance across life‐history stages

“…This naturally produces uninfected adults and offers a convenient way to manipulate the infection in the adult and larval stage independently, without the use of artificial treatments or the risk of overlapping parasite cohorts. In addition, T. confusum should greatly benefit from immune priming because it lives in dense colonies and is prone to re‐infection by the same parasite (Janovy et al , 2007). Previous studies on the closely related Tribolium castaneum also suggest that Tribolium can show highly specific immune priming (Roth et al , 2009) and alter their development in response to different bacterial pathogens (Roth & Kurtz, 2008).…”

Why American Higher Education Needs Parasitologists

“…The new species that I've had a hand in describing, including those by my students and colleagues working with my students, are in 4 different phyla-Platyhelminthes, Apicomplexa, Myxozoa, and Euglenozoa-as well as several genera within a single phylum (Self and Janovy, 1965;Daggett et al, 1972;Janovy et al, 1989Janovy et al, , 2007Richardson and Janovy, 1990;Clopton et al, 1991Clopton et al, , 1992Clopton et al, , 1993Ferdig et al, 1991;Percival et al, 1995;Helt et al, 2003;Jirku˚et al, 2006). Although this list is far short of those compiled by parasitologists working primarily in systematics, what I've come to call the ''Olsen lessons'' were learned not only by me, but also, and more importantly, by my students in the act of compiling it.…”

“…My impression, shared by many colleagues, is that these forces are shaping our nation's intellectual resources in a way that is not necessarily consistent with the traditional ideals of American higher education (Delbanco, 2012; see also http://chronicle.com/article/College-at-Risk/130893/). Yet it doesn't take much of a hands-on field experience, especially under the guidance of a parasitologist, to capture that sense of wonder, re-kindle the kind of curiosity that flourishes in an exploratory situation, and foster the multi-lens view of nature described above (Janovy, 1994Esch, 2004;Janovy and Major, 2009). I've seen it happen countless times: cut open a host, find parasites, wonder how they got there, get introduced to relevant literature, struggle through the art of specimen preparation, talk about your experience with people who appreciate the seductive power of discovery, and you're hooked.…”
