Between March 2019 and February 2020, Asian long-horned ticks (Haemaphysalis longicornis Neumann, 1901) were discovered and collected for the first time in one middle and seven eastern Tennessee counties, facilitated by a newly developed passive and collaborative tick-surveillance network. Network collaborators included federal, state, county, university, and private resource personnel working with companion animals, livestock, and wildlife. Specimens were collected primarily from dogs and cattle, with initial detections of female adult stage ticks by stakeholders associated with parasitology positions (e.g., entomologists and veterinary parasitologists). Initial county tick detections were confirmed with morphological and molecular identifications, and then screened for the presence of animal-associated pathogens (Anaplasma marginale, Babesia species, Ehrlichia species, and Theileria orientalis), for which all tests were negative. Herein, we describe the identification and confirmation of these tick specimens as well as other results of the surveillance collaboration.

The Early Carnian (Upper Triassic) phaceloid coral originally described by Volz (1896) asHexastraea fritschi, type species ofQuenstedtiphylliaMelnikova, 1975, reproduced asexually by “Taschenknospung” (pocket-budding), a process documented herein for the first time. This type of budding is recognized only in the Amphiastraeidae, a family thus far recorded only from Jurassic-Cretaceous strata. Similar to amphiastraeids,Quenstedtiphyllia fritschi(Volz, 1896) has separate septal calcification centers and a mid-septal zone built of serially arranged trabeculae. The most important discriminating characters of the new amphiastraeid subfamily Quenstedtiphylliinae are one-zonalendotheca and radial symmetry of the corallite in the adult stage (in contrast to two-zonal and bilateral symmetry in the adult stage in Amphiastraeinae).Quenstedtiphyllia fritschishares several primitive skeletal characters (plesiomorphies) with representatives of Triassic Zardinophyllidae and, possibly, Paleozoic plerophylline rugosans: e.g., thick epithecal wall and strongly bilateral early blastogenetic stages with the earliest corallite having one axial initial septum. To interpret the phylogenetic status of amphiastraeid corals, we performed two analyses using plerophylline rugosans and the solitary scleractinianProtoheterastraea, respectively, as the outgroups. The resulting phylogenetic hypotheses support grouping the Zardinophyllidae with the Amphiastraeidae in the clade Pachythecaliina (synapomorphy: presence of pachytheca). Taschenknospung is considered an autapomorphy for the Amphiastraeidae. This study is the first attempt to analyze the relationships of the Triassic corals cladistically.

Bucephalus haimeanus is shown to be an estuarine species. The cercaria from Cardium edule is briefly redescribed to include details of the nephridial system. The metacercaria is described for the first time, having been obtained experimentally in Pomatoschistus microps and Pleuronectes platessa. In Pomatoschistus microps it survives at least 10 months, development within this host being completed within 2 months. The main site of infection is the liver. Migration is completed within 1 h and in some instances within 10 min. During this period the metacercaria actively feeds on host tissue, the gut being greatly distended with food on encystment. A hyaline cyst wall is maintained throughout the remaining life of the metacercaria. ‘O’ group plaice are highly susceptible to invasion by B. haimeanus during early summer and 100% infections were recorded in catches from Ynys-las, Dovey Estuary, in June. Experiments showed that only 2% of the metacercariae survived more than two weeks and that ‘l’ group plaice were non-susceptible to infection. Plaice are therefore considered accidental hosts. The metacercaria was linked with the adult stage from Morone labrax on the basis of comparative morphology and the ecology of the hosts, the bass entering the estuarine habitat during the summer months. The adult is considered synonymous with Bucephalus minimus Stossich, 1887.

AbstractThe six-spotted leafhopper, Macrosteles fascifrons (Stål), is the only known host of Pachygonatopus minimus Fenton; parasitism has reached 37%. The female adult is also a predator of the leafhopper. In the adult stage of the parasite the sexes differ in form, color and habits; the male is winged and the female wingless. The egg is laid in the abdomen of the host. As the larva develops it protrudes through an intersegmental membrane. There are five larval instars. The first four are sedentary and attached to the host; the fifth is an active feeding stage. The larva spins a cocoon within which it pupates. The period from egg to adult is about 28 days. P. minimus does not provide effective control of the leafhopper.

Four new leaf mining Oecophyllembiinae (Gracillariidae) species are described from Chinaand Japan: Metriochroa sym-plocosella sp. nov. (host plants: Symplocos anomala, S. sumuntia, Symplocaceae) from China, Guttigera schefflerella sp. nov. (host plant: Schefflera octophylla, Araliaceae), Eumetriochroa araliella sp. nov. (host plants: Dendropanax trifidus, Evodiopanax innovans, Eleutherococcus sciadophylloides and Fatsia japonica, Araliaceae) and Corythoxestis tricalysiel-la sp. nov. (host plant: Tricalysia dubia, Rubiaceae) from Japan. Corythoxestis sunosei (Kumata, 1998) is recorded from new host plants: Adina pilulifera and Mussaenda parviflora, Rubiaceae, from Japan. The female adult and pupal morphol-ogies, life history and host plant of the genus Guttigera are described for the first time. Pupae of seven species of four genera: Corythoxestis, Eumetriochroa, Guttigera, and Metriochroa, are described for the first time. We provide morpho-logical diagnostic differences between species and genera of Oecophyllembiinae and Phyllocnistis. Our preliminary data suggest that Oecophyllembiinae species have three valuable pupal diagnostic characters: 1) cocoon cutter with unique lat-eral processes or setae on the clypeus, 2) tergal spines with only a pair of dorsal setae, and 3) cremaster with more than two pairs of caudal processes, while Phyllocnistis species possess 1) cocoon cutter without lateral processes or setae on clypeus, 2) tergal spines with a pair of dorsal setae and dorsal hooks, and 3) cremaster with only a pair of caudal processes.

AbstractThis communication presents precise percentile values for birth weight, birth length and cranial circumference of infants in Mecklenburg-Pomerania, Germany.Based on data from the German Perinatal Survey of the years 1994–2011 in Mecklenburg-Pomerania, the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for birth weight, birth length and head circumference are specified. The measurements of a total of 174 084 infants from non-multiple births are shown.The statistically calculated percentile values are presented in tabular and graph forms. The mean birth weight of the infants was 3 437.8 g. The average age of the mothers was 27.9 years. The average duration of pregnancy was 39.4 complete weeks.The insights gained from many years of data collection are presented as standardised, regional percentile values and curves for Mecklenburg-Pomerania for the first time. The differentiated presentation for the federal state opens the possibility for individually tailored consultations in clinical practice and may provide support for recognised national curves for these values.

The goal of this research was to understand the biology of P. marginatus, a common pest for papaya plants.  This research used 1 type of treatment which was repeated 10 times. The results of this research were intended to illustrate the average development time of each development phase of P. marginatus.  These phases were: the egg phase (6 days), the female nymph phase (10 days),  the male nymph phase (17 days), female adult stage (11 days), male adult stage (3 days).  On average, the female life cycle was 27 days, and the male life cycle was 26 days.  On average, the pre-fertile stage lasted 4 days, the fertile stage lasted 6 days and the post fertile stage lasted 1 day. On average the pre-egg-laying adult stage lasted 4 days, the egg-laying adult stage lasted 6 days and the post-egg-laying stage lasted 1 day.  After the egg-laying stage, the average fecundity of P. marginatus was 370 eggs per female and from these, a total of 350 offspring were hatched per individual.  The ratio of surviving Descendents to reproductive couples of P. marginatus white lice was 9:1.
