Biology and Ecology of Sirex, Deladenus and Amylostereum in North America
BIOLOGY AND ECOLOGY OF SIREX, DELADENUS AND AMYLOSTEREUM IN NORTH AMERICA A thesis Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Master of Science By Isis Andréia Lima Caetano January, 2017 i © 2017 Isis Andréia Lima Caetano iii Abstract Sirex noctilio is a woodwasp that attacks stressed or dying pine trees. It is native to Eurasia and North Africa but has been invasive in the southern hemisphere since the early 1900s. It was found for the first time in the United States in New York State in September 2004 and in Ontario in 2005. Since then it has spread to a total of seven northeastern US states. S. noctilio is more aggressive than the native pine specialist Sirex nigricornis and it is able to kill living pines by injecting a phytotoxic venom and its symbiotic fungus Amylostereum areolatum into tree trunks. The Kamona strain of the nematode Deladenus siricidicola has been extensively used as a biological control agent against invasive S. noctilio in the Southern Hemisphere, where it sterilizes female hosts by entering the eggs and making them inviable. In North America, a non- sterilizing (NS) strain of D. siricidicola, thought to have been introduced with S. noctilio, is commonly found parasitizing this invasive woodwasp. Species of Deladenus that parasitize Sirex have a parasitic form as well as a mycophagous form. Studies were conducted to understand 1. Sirex mating behavior and sexual receptivity, 2. the growth of two strains of D. siricidicola, Kamona and NS, with different strains and species of Amylostereum spp. -

E-mail: [email protected] ABSTRACT: The prevalence of intestinal helminth of residents of Naraguta rural community in Central Nigeria is presented. Out of 700 stool specimens examined between January and July 1999, 261 (37.3%) were positive for helminthic infections. Helminths encountered include Hookworm, Schistosoma mansoni, Trichuris trichiura, Strongyloides stercoralis, Ascaris lumbricoides, and Hymenolepis nana. Hookworm was the most predominant, followed by S. stercoralis, S. mansoni and A. lumbricoides with T. trichiura as the least. Intestinal helminthiasis was equally prevalent for males and females. However, infection rates were high among persons below ten years of age, in toddlers, housewives and farmers than others. Persons defecating in the bush harbored more worms (56.7%) than pit latrine users (43.3%). Free medical diagnosis in most rural communities in Nigeria are probably justifiable and should be promoted and/or sustained by government. -
Hymenolepiasis in a Pregnant Woman: a Case Report of Hymenolepis Nana Infection
Open Access Case Report DOI: 10.7759/cureus.3810 Hymenolepiasis in a Pregnant Woman: A Case Report of Hymenolepis nana Infection Venkataramana Kandi 1 , Sri Sandhya Koka 1 , Mohan Rao Bhoomigari 1 1. Microbiology, Prathima Institute of Medical Sciences, Karimnagar, IND Corresponding author: Venkataramana Kandi, [email protected] Abstract Hymenolepiasis is an infection caused by Hymenolepis nana (H. nana) and H. diminuta (H. diminuta). Hymenolepiasis is prevalent throughout the world with human infections with H. nana being frequently reported in the literature as compared to H. diminuta. Hymenolepiasis is more frequent among children, and most human infections remain asymptomatic and self-limited. Symptoms including abdominal pain, diarrhea, and vomiting are frequently noted in the cases of heavy infections. We report a case of hymenolepiasis caused by H. nana in a pregnant woman. Categories: Obstetrics/Gynecology, Infectious Disease, Public Health Keywords: hymenolepiasis, hymenolepis nana, h. nana, h. diminuta, children, adults, asymptomatic, pregnant woman Introduction Human infection caused by the cestodes belonging to the genus Hymenolepis is called as hymenolepiasis. The cestodes are broadly classified as pseudophyllidean and cyclophyllidean cestodes. Hymenolepis species (spp.) fall into the cyclophyllidean group, which is characterized by the presence of four cup-like structures in the scolex/head called as suckers. The suckers are either armed (presence of hook-like structures) or unarmed (no hooks). Hymenolepis spp. are armed with the presence of a single round of hooks around the suckers. Among the Hymenolepis spp., H. nana is commonly called as a dwarf tapeworm and H. diminuta is referred to as a rat tapeworm. H. nana frequently causes human infections and may also cause infections in rats, whereas H. -
The Sirex Woodwasp, Sirex Noctilio: Pest in North America May Be the Ecology, Potential Impact, and Management in the Southeastern U.S
SREF-FH-003 June 2016 woodwasp has not become a major The Sirex woodwasp, Sirex noctilio: pest in North America may be the Ecology, Potential Impact, and Management in the Southeastern U.S. many insects that are competitors or natural enemies. Some of these insects compete for resources AUTHORED BY: LAUREL J. HAAVIK AND DAVID R. COYLE (e.g. native woodwasps, bark and ambrosia beetles, and longhorned beetles) while others (e.g.parasitoids) are natural enemies and use Sirex woodwasp larvae as hosts. However, should the Sirex woodwasp arrive in the southeastern U.S., with its abundant pine plantations and areas of natural pine, this insect could easily be a major pest for the region. Researchers have monitored and tracked Sirex woodwasp populations since its discovery in North America. The most common detection tool is a flight intercept trap (Fig. 2a) baited with a synthetic chemical lure that consists of pine scents (70% α-pinene, 30% β-pinene) or actual pine branches (Fig. 2b). Woodwasps are attracted to the odors given off by the lure or cut pine branches, and as they fly toward the scent they collide with the sides of the trap and drop Figure 1. The high density of likely or confirmed pine (Pinus spp.) hosts of the Sirex woodwasp suggests the southeastern U.S. may be heavily impacted should this non-native insect become into the collection cup at the bottom. established in this region. The collection cup is usually filled with a liquid (e.g. propylene glycol) that acts as both a killing agent and Overview and Detection preservative that holds the insects until they are collected. -

Hurley. Tel.: +27 12 4205822; fax: +27 12 4203960. e-mail: [email protected] Abstract 1. The parasitoid wasp Ibalia leucospoides is native to the northern hemisphere and has been introduced to the southern hemisphere as a biological control agent for the invasive woodwasp Sirex noctilio. Two sub-species of the parasitoid, I. leucospoides leucospoides (Palearctic distribution) and I. leucospoides ensiger (Nearctic distribution), were introduced and are reported to have hybridized. 2. Despite extensive records of the numbers and origins of the wasps imported into the southern hemisphere, nothing is known regarding their current population diversity. We investigated the genetic variation of I. leucospoides in its native and introduced ranges using mitochondrial (COI) and nuclear (ITS) markers. 3. Mitochondrial DNA diversity in the introduced range was limited, with only five haplotypes, but sequence divergence between these haplotypes was high. Similarly, the ITS rDNA sequences revealed multiple clades present in the introduced range. 4. These results reflect introductions from a wide geographical range, but where genetic bottlenecks have possibly reduced the genetic diversity. The data further reflect the origin of the I. leucospoides populations in South America and South Africa from New Zealand or Australia. -

Abstract Hymenolepis nana infestation is commonly diagnosed in school-aged children and very rarely reported in adults patients in Saudi Arabia. We encountered an adult Saudi patient with a H. nana infection. The patient presented with a chronic history of vague abdominal pain and diarrhoea. He had negative laboratory examinations as well as a negative report on stool sample analysis. After misdiagnosis of his symptoms as Irritable Bowel Syndrome and failed treatment for Irritable Bowel Syndrome, he was readmitted to hospital. After thorough but negative physical, systemic and laboratory examinations, and stool sample microscopy, the patient underwent careful ileo-colonoscopy. -

SIREX NOCTILIO HOST CHOICE AND NO-CHOICE BIOASSAYS: WOODWASP PREFERENCES FOR SOUTHEASTERN U.S. PINES by JAMIE ELLEN DINKINS (Under the Direction of Kamal J.K. Gandhi) ABSTRACT Sirex noctilio F., the European woodwasp, is an exotic invasive pest newly introduced to the northeastern U.S. This woodwasp kills trees in the Pinus genus and could potentially cause millions of dollars of damage in the southeastern U.S., where pine plantations are extensive. At present, little is known about the preferences of this wasp for southeastern pine species, and further, little methodology exists as related to conducting host choice or no-choice bioassays with this species. My thesis developed methodology to successfully perform S. noctilio host choice and no-choice bioassays (both colonization and emergence from bolts), examined S. noctilio behavioral and developmental responses to southeastern U.S. pine species using bolts, and investigated possible mechanisms to explain these behavioral responses. Results indicated larger bolts were preferred to smaller bolts by S. noctilio, and P. strobus and P. virginiana were preferred out of six southeastern species in host choice bioassays.
