Catalog of the Eriophyoidea (Acarina: Prostigmata) of the world.

This catalogue of the Eriophyoidea includes all eriophyoid mites acknowledged to the authors on a world-wide basis, as of August, 1993. Indexes to species names, food plants and food plant common names, and a precis of the Eriophyoidea, area unit enclosed. Replacement names for pre-occupied names of one genus and seventeen species area unit provided. These embody the renaming of Aculus ribis Manson, 1989, as A. mansoni; of Eriophyes euphorbiae (Mohanasundaram), 1983, as E. antiquorum; of E. alangii (Mohanasundaram), 1981, as E. coimbatoriensis; of Knorella bambusae Kuang & Zhuo, 1989, as K. fuzhoui; of Phyllocoptruta sapii Kuang and Zhou, 1989, as P. kuangii; and of E. lionotussensu Wilson 1970, as Vasates oldfieldi.

Ticks of Venezuela (Acarina: Ixodoidea) with a key to the species of Amblyomma in the Western Hemisphere

Forty-nine species in two families and ten genera ar recorded for South American nation. A key to the species of Amblyomma within the New World is given. Host and vicinity records ar provided for every species. No new species ar reportable however the subsequent seventeen species ar new for the fauna of Venezuela: Autricola silvai Cerný, 1967, Ornithodoros boliviensisO. brodyi Matheson, 1935, O. puertoricensis Fox, 1947, O. rossi Kohls, Sonenshine and Clifford, 1965, O. stageri Cooley and Kohls, 1941, O. yumatensis Cooley and Kohls, 1941, O. marinkellei Kohls and Clifford, 1969, O. viguerasi Cooley and Kohls, 1941, Amhblyomma extraoculatum Neumann, 1899, A. incisum Neumann, 1906, A. naponense (Packard, 1869), A. oblongoguttatum Koch, 1844, A. pacae Aragão, 1911, A. scalpturatum Neumann, 1906, A. tigrinum Koch, 1844, genus Ixodes auritulus cluster.

Phytoseiidae (Acarina) Associated with Citrus in Florida

Investigations by Citrus Experiment Station employees at Lake Alfred involved with the factors poignant biological management of citrus insects and mites in Florida have recently been intense. Before associate degree analysis of biological management may be created it’s necessary that as several as attainable of the factors be recognized and known. classification studies have, therefore, received primary attention. Fisher (1947, 1950 and 1951) has according on many diseases of citrus insects and mites and is continuous the search. A survey of parasites and predators was initiated in Gregorian calendar month, 1951. This paper is that the initial of a planned series listing and describing the predators and parasites of citrus insects and mites in Florida. [3]

Cleavage in Cheyletus eruditus (Acarina)

IN his work on the biology of the thelytokously nonsexual mite, Cheyletus eruditus, Hafiz1 states: “The single nucleus of the egg cell rises to the surface of the nutrient and by dividing provides rise to one layer of cells forming the blastoderm”. He additionally states that simply before oviposition 4–7 little nuclei could also be found coming into the animal tissue layer of protoplasm which blastodisc formation is completed a pair of time unit. once deposition. so he ascribes to the present mite a kind of superficial cleavage that is already continuing at the time of oviposition, a read not confirmed by my observations.

Spatial and Temporal Distribution of Cassava Green Mite, Mononychellus tanajoa Bonder (Acarina: Tetranychidae) in Tanzania

Two diagnostic surveys were conducted throughout the 2015 and 2016 growing seasons in 3 major cassava growing zones of African nation. The studies geared toward establishing the spatial  and temporal distribution of M. tanajoa on ordinarily grownup business cassava varieties landraces in African nation. a complete of two,700 plants in ninety fields were assessed in 9 districts of that 5 fields were within the Lake zone and 2 districts in every of the Southern and jap zones. Results indicated that the distribution of M. tanajoa considerably (P = .05) differed across seasons, Southern and Lake zones were statistically similar and better in M. tanajoapopulation than the jap zone. Crop age, altitude and cassava varieties considerably (P = .05) influenced the population of M. tanajoa whereas crop mixture (inter cropping) had no important impact in each seasons. [5]
