| life history of kampimodromus aberrans as a predator of phytoptus avellanae (acari: phytoseiidae, phytoptidae). | the biology of kampimodromus aberrans (oudemans), a predator of the big bud mite, phytoptus avellanae nalepa, was studied under laboratory conditions. all experiments were conducted on hazelnut leaf discs in an incubator at 25 +/- 1 degrees c, with 16:8 h l:d, at an average daily relative air humidity of 76%. observations were made twice daily for the immature stages and daily for the adults to determine developmental time, survival and fecundity. the mean developmental time for females was 6.90 ... | 2006 | 16550331 |
| comparative confocal microscopy of internal genitalia of phytoptine mites (eriophyoidea, phytoptidae): new generic diagnoses reflecting host-plant associations. | confocal laser scanning microscopy (clsm) methods are still rarely used by acarologists although they are very appropriate for studying minute arthropod pests, especially eriophyoid mites. in this paper, the female reproductive system of phytoptines, including the bud mite phytoptus avellanae, the well-known pest of hazelnut, was studied using clsm and resulted in new interpretations of the functioning anatomy of phytoptid genitalia. comparison of cuticle-lined internal genitalia, based on novel ... | 2014 | 24037537 |
| a study of embryonic development in eriophyoid mites (acariformes, eriophyoidea) with the use of the fluorochrome dapi and confocal microscopy. | the embryonic development of four eriophyoid mite species, cecidophyopsis ribis, phytoptus avellanae, oziella liroi and loboquintus subsquamatus, has been studied with the use of fluorochrome dapi and confocal microscopy. the first three nuclear divisions occur on the egg periphery (the groups of 2, 4, and 6 nuclei have been recorded), while the biggest part of yolk remains undivided. after four or five nuclear divisions all nuclei are situated only in one sector of the embryo, while other secto ... | 2016 | 26530993 |
| cryptic speciation within phytoptus avellanae s.l. (eriophyoidea: phytoptidae) revealed by molecular data and observations on molting tegonotus-like nymphs. | hazelnut big bud mite, phytoptus avellanae nalepa, is one of the most harmful pests of corylus spp. (corylaceae) worldwide. herein, we show that this species represents a complex of two cryptic species: one that lives and reproduces in buds causing their enlargement ('big buds') and drying, whereas the other is a vagrant living on leaves, under bud scales and in catkins, based on phylogenetic analyzes of mitochondrial cytochrome c oxidase subunit i (coi) dna and the nuclear d2 region of 28s rdna ... | 2016 | 26530992 |
