Tribolonychus collyerae Zhang & Martin is redescribed based on the larva, protonymph, deutonymph and adult male and female specimens from New Zealand. The ontogenetic development of chaetotaxy in Tribolonychus and the number and position of solenidia on tibia I are discussed. Patterns of setal addition on leg III and IV from larva to adult in Trilobonychus are different from the basic pattern o...
Abstract Background An entomopathogenic nematode (EPN) was recovered by using Galleria baiting technique from the soils of marigold fields Noida, Uttar Pradesh, India. Based on morphological, morphometrical and molecular characterizations, isolated strain identified as Steinernema abbasi tagged CS38. The conspecific to original description with minor deviations. Infective juveniles (IJs) presen...
The nemertide toxins from the phylum Nemertea are a little researched family of neurotoxins with potential for development as biopesticides. Here we report recombinant production α-1 (α-1), 65-residue inhibitor cystine knot (ICK) peptide Lineus longissimus, known to target insect voltage-gated sodium channels. insecticidal activity was assessed and compared well characterised ICK venom peptide,...
Two brothers with visceral larva migrans caused by Trichuris vulpis were diagnosed after they had been investigated for an eosinophilia. Both patients were almost asymptomatic. The diagnosis of visceral larva migrans was based on the results of immunoelectrophoretic studies and no liver biopsy was performed. After administration of thiabendazole, the number of eosinophils and serum total IgE le...
Immatures of Mesomphalia gibbosa (Fabricius, 1781) and Mesomphalia turrita (Illiger, 1801) (Coleoptera, Chrysomelidae, Cassidinae, Mesomphaliini) are described based on specimen collections from Rio de Janeiro state, Brazil. The last-instar larva and pupal exuviae of M. gibbosa (Fabricius, 1781) and the eggs, first-instar larva, and pupa of M. turrita (Illiger, 1801) are described, photographed...
The fourth instar larva and pupa of Bezzia blantoni Spinelli & Wirth (1989) are described, illustrated and photomicrographed by using phase-contrast microscopy and Scanning Electron Microscope (SEM). The larva, which shows features typical to carnivorous larvae, is compared with that of B. roldani Spinelli & Wirth. The species is recorded for the first time from the Martín García island, locate...
The fourth instar larva and pupa of Culicoides debilipalpis Lutz, 1913 are described, illustrated, and photomicrographed from material collected in tree-holes of Salix sp. in Entre Rios Province, Argentina by using binocular, phase-contrast, and scanning electron microscopy. Measurements of instars I–IV are also presented. The larva shows features typical to carnivorous-predatory larvae, as wel...
Cutaneous larva migrans caused by the larvae of animal hookworms is the most frequent skin disease among travelers returning from tropical countries. Complications (impetigo and allergic reactions), together with the intense pruritus and the significant duration of the disease, make treatment mandatory. Freezing the leading edge of the skin track rarely works. Topical treatment of the affected ...
A forensic entomological study was conducted using monkey carcasses (Macaca fascicularis Raffles) that were placed in either an outdoor or indoor environment at a coastal area in Tanjung Sepat, Selangor, Malaysia during May until August 2008. We collected pupae of Chrysomya rufifacies (Marquart) from the carcasses and kept them individually. The emergence of 13 parasitic microhymenopteran, from...
