Gonotrophic cycle of Leptoconops borealis (Diptera, Ceratopogonidae)]

Data are given concerning the gonotrophic cycle in fully engorged specimens of Leptoconops borealis, a mass blood sucker from the coast of the sea of Azov. In fully engorged females the repetition of gonotrophic cycles and degeneration of ovaries take place under the effect of Mermitoidea parasitism.     

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) and Paleotrypanosoma burmanicus gen. n., sp. n. (Kinetoplastida: Trypanosomatidae), a biting midge--trypanosome vector association from the Early Cretaceous

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) is described from a blood-filled female biting midge in Early Cretaceous Burmese amber. The new species is characterized by a very elongate terminal flagellomere, elongate cerci, and an indistinct spur on the metatibia. This biting midge contained digenetic trypanosomes (Kinetoplastida: Trypanosomatidae) in its alimentary tract and salivary glands. These trypanosomes are described as Paleotrypanosoma burmanicus gen. n., sp. n., which represents the first fossil record of a Trypanosoma generic lineage.     

Ecology of the biting midge Leptoconops albiventris in French Polynesia. I. Biting cycle and influence of climatic factors

Abstract. The diurnal biting cycle of Leptoconops albiventris de Meijere (Diptera: Ceratopogonidae) is described from beaches of Nuku-Hiva, French Polynesia. Biting activity increased during the morning, diminished during the afternoon and was sufficiently intense to constitute a nuisance throughout the whole day. Correspondence Analysis indicated that climatic factors influenced biting activity. Activity was initiated by and positively associated with sunshine, whereas high temperatures, increased wind speed and rainfall were factors limiting activity. Decreased density of females during the dry season and their low capacity for dispersal were considered potentially advantageous with respect to control.     

Ecology of the biting midge Leptoconops albiventris in French Polynesia. II. Location of breeding sites and larval microdistribution

Abstract. The habitat of the immature stages of Leptoconops albiventris de Meijere (Diptera: Ceratopogonidae) was found to be in beach sand located above the high tide level near creeping vegetation. The immatures were restricted to a narrow strip and most occurred in the upper 6 cm of sand. Within a given breeding site, larvae were aggregated in their distribution. Eggs were layed on the bare sand surface, from which the larvae apparently dispersed to the plant-covered sand and to deeper strata, before returning to the surface for pupation and emergence. The nature of these breeding sites suggests that it is possible to control L.albiventris populations. Recovery of immature stages from sand samples by a flotation method is described.     

Ecology of the biting midge Leptoconops albiventris in French Polynesia. III. Influence of abiotic factors on breeding sites. Towards ecological control?

Abstract. Correspondance Analysis was used to determine the significant abiotic factors influencing the ecology of the immature stages of Leptoconops albiventris (Diptera: Ceratopogonidae). The breeding places required strict environmental conditions: fine and well-sorted sand, with low conductivity and humidity. However, the microdistribution of the immature stages within a breeding site does not depend on such factors. Modifying physical parameters in the larval breeding areas might be an important component in future ecological control programmes against L.albiventris populations.     

Synthesis and luminescence properties of a blue-emitting Sr(3.5) Y(6.5) O(2) (PO(4) )(1.5) (SiO(4) )(4.5) :Eu(2+) phosphor

A novel blue‐emitting Sr_3.5Y_6.5O₂(PO₄)_1.5(SiO₄)_4.5:Eu²⁺ phosphor was synthesized via a solid‐state reaction. Powder X‐ray diffraction (XRD) analysis demonstrated that the Sr_3.5Y_6.5O₂(PO₄)_1.5(SiO₄)_4.5 host had a hexagonal crystal structure in the space group P6₃/m and unit cell parameters a = 9.418 Å, c = 6.900 Å. The as‐prepared phosphor showed a blue emission and all the main emission peaks were located at around 466 nm for different excitation wavelengths of 297, 333 and 391 nm. The temperature dependence of the photoluminescence property was investigated in the range 20–250 °C, and the emission intensity decreased to 71% of the initial value at room temperature on increasing the temperature to 150 °C. According to the classical theory of fluorescent thermal quenching, the activation energy (ΔE) for the thermal quenching luminescence of the as‐prepared Sr_3.45Y_6.5O₂(PO₄)_1.5(SiO₄)_4.5:0.05Eu²⁺ phosphor was determined to be 0.20 eV.
