Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the canine respiratory system (final host). The discharged eggs infect many plant feeder animals including human causing visceral and nasopharyngeal linguatulosis which is known as "Marrara syndrome". In current study, the prevalence of infection with L. serrata nymphs in mesenteric lymph nodes (...

Eggs, crawlers, early nymphs, late nymphs, and adults of the pink hibiscus mealybug, Maconellicoccus hirsutus (Green), were tested for their susceptibility to methyl bromide in 2-h laboratory fumigations at ambient conditions (25 degrees C, 95% RH). Dose-response tests indicated that the egg was the most susceptible life stage with an LC99 of 20.2 mg/liter. Based on probit analysis of dose-resp...

The insecticidal toxicities of five essential oils against Pochazia shantungensis adults and nymphs, newly recorded pests, were evaluated. The LC50 values of Thymus vulgaris, Ruta graveolens, Citrus aurantium, Leptospermum petersonii and Achillea millefolium oils were recorded as 57.48, 84.44, 92.58, 113.26 and 125.78 mg/L, respectively, against P. shantungensis nymphs using the leaf dipping bi...

This is a report of tick species, parasite prevalence and infestation intensity of birds in a forest fragment (18° 56' 57'' S and 48° 12' 14'' W) within the Brazilian cerrado (savanna), in the municipality of Uberlândia, State of Minas Gerais, Brazil. A total of 162 birds from 26 species were captured. One adult tick, 296 larvae and 67 nymphs were found on passerine birds. Of these, it was iden...

Crimean-Congo hemorrhagic fever (CCHF) virus was transmitted from infected adult Hyalomma ticks to uninfected larval and nymphal Hyalomma ticks while cofeeding on a guinea pig host that did not have a detectable viremia. When tested after feeding with infected adults, three (0.8%) of 370 H. truncatum larvae contained detectable CCHF virus (mean virus titer 10(1.6) plaque-forming units [PFU]/tic...

Abstract The family Polymitarcyidae, with a worldwide distribution, includes mayflies large burrowing nymphs. South America harbors the highest diversity of this family, including subfamilies Asthenopodinae and Campsurinae. In work, three new species belonging to genera Tortopsis Tortopus (Campsurinae) are described based on adults nymphs from Colombia: toro sp. nov. , andaki coreguaje Addition...

Material collected between 1984 and 1988 in Guinea Mali 2003 2008 the Ivory Coast substantially increased our knowledge of Labiobaetis Novikova & Kluge West Africa. We identified eight different species using morphological characters. One species, L. ediai sp. nov. , is new to science; it described illustrated, based on its nymphs. The status boussoulius (Gillies, 1993) discussed diverg...

Atopophlebia pitculya is described from adults and nymphs from western Ecuador. Nymphs were found in leaf packs in small streams that can be intermittent in the dry season. This species along with Atopophlebia fortunensis are found associated with the accreted terranes of Central America, the Western Andes of Colombia, and the coastal mountains in northwestern Ecuador.

The cicada Meimuna mongolica (Distant) (Hemiptera: Cicadidae) is one of the most important pests of economic forest in Guanzhong Plain of Shaanxi Province, China. Information about ecological characteristics and some sustainable control measures of this species is urgently required for its control. In this study, nymphal instars, morphological variation, vertical distribution, and population de...

Recent research on the treehopper tribe Telamonini has focused on their classification and Nearctic distribution but little has been published on their biology, including detailed information on their host plants as well as data on their nymphal stage. Any studies including host plant data have emphasized adult records (often unreliable due to their movements), largely ignoring the nymphs, whic...
