Gymnosporangium Sabinae

The fungus Gymnosporangium sabinae (Dicks.) Winter was found only at three locations during the years 1965 to 1990 in Slovakia, they were the Arboretum at Mlyňany, Topoľčianky and Gbely (JUHÁSOVÁ 1973, 1975, 1998). We noticed a more frequent occurrence of this fungus during recent years. The life cycle, range of woody host plants and degree of damage on pear leaves at selected locations inSlovakia are described.

Mites have hostplant specifications or host plants. Mites can be destructive and deadly of which is the host plants a mango crop. Mites on mango crops will cause the leaves yellow and fall off prematurely. This is will lead to the disruption of the productivity of mango. It is necessary for research to identify the mites that infect the mango crop. The method is carried out by direct observation. Mites were taken from the surface of mango leaves later in preservation with several levels of concentration of alcohol, and polyvinyl laktofenol. Then, observed under a microscope and documented for identification purposes. Mites on the leaf surface of manalagi mango (<em>Mangifera indica</em>) found two species, it is <em>Oligonychus</em> sp. and <em>Oligonychus ilicis</em> (Family: Tetranychidae, Superfamily: Tetranychoidea). <em>Oligonychus</em> sp. hallmark is rounded body shape like a spider, with a body is transparent and there are two long seta on posterior part. While <em>Oligonychus ilicis</em> has a characteristic elongated rounded body shape, red, and there is a short posterior seta. <em>Oligonychus</em> sp. and <em>Oligonychus ilicis</em> live as parasites on the surface of mango leaves that can lead to wrinkled leaves, yellow and to fall. <em>Oligonychus</em> life cycle starts from the eggs develop into Nympha and then adult.

SUMMARY Female aging is a process that involves hypoestrogenism time, the individual impact on each woman, and what we can do as experts to reduce morbidity and provide quality of life. This natural process in the female life cycle has been of concern to women after menopause. Changes in different biophysical and psychosocial aspects, and their individual experiences, have repercussions on the lives of patients seeking specialized and multidisciplinary support to reduce the harmful effects of prolonged hypoestrogenism. Overweight and obesity, inadequate living habits and the presence of multi-morbidities cause damage to the quality of life and impact the functional capacity. Behavioral prescription and hormone therapy are among the treatments given to ease symptoms and reduce morbidity. A better understanding of these factors can help identify groups that require more care after menopause.

Members of the genus Cytospora are often reported as endophytes, saprobes or phytopathogens, primarily causing canker diseases of woody host plants. They occur on a wide range of hosts and have a worldwide distribution. Although several species have in the past been reported from China, the vast majority are not known from culture or DNA phylogeny. The primary aim of the present study was thus to clarify the taxonomy and phylogeny of a large collection of Cytospora species associated with diverse hosts in China. Cytospora spp. were collected in northeast, northwest, north and southwest China, indicating that the cold and dry environments favour these fungi. In this paper, we provide an assessment of 52 Cytospora spp. in China, focussing on 40 species represented by 88 isolates from 28 host genera. Based on a combination of morphology and a six-locus phylogeny (ITS, LSU, act1, rpb2, tef1-α and tub2), 13 new species and one new combination are introduced. The majority of the species investigated here appear to be host-specific, although further collections and pathogenicity studies will be required to confirm this conclusion.

The life cycle connection between spermogonial and aecial stages of a rust fungus found on Abies holophylla and uredinial and telial stages on Tilia mongolica and T. mandshurica collected in northeast China were confirmed by phylogenetic analyses. The rust, identified as Pucciniastrum tiliae, was confirmed by morphological observations. The life cycle of this rust fungus is reported for the first time in China, and A. holophylla and T. mongolica represent new host plants for the species.

In this work the duration of the life-cycle of Metaphycus helvolus (Comp.) (parasite mainly on the third stage), Μetaphycus affinis stanley (Comp.) (parasite mainly on the third stage) and Μetaphycus lounsburyi (How.) (parasite mainly on the fourth stage) (Hymenoptera: Encyrtidae) on S. οleae, developed on different substrates, i.e. potato sprouts and plants of Nerium oleander, under laboratory conditions was determined. Among the Hymenoptera parasitizing S. oleae on Corfu, M, helvolus and M. lounsburyi, are of particular importance M. affinis stanley was introduced in Corfu in 1976 and despite the fact that the population of S. οleae in the release area was practically eliminated from other factors shortly after the release of the parasite, there is evidence that the parasite was finally established. The above parasites can be successfully reared on S. οleae developed both on potato sprouts and Nerium oleander. The study was carried out at 23±1°C, 65-70% R.H. and 12 hours of artificial light per day. For each species, 3 potato sprouts and three plants of Nerium oleander in pots infested with S. οleae were placed in each 60X30X40 cm cage. The host insects were oviposited in by adult parasites introduced into the cages and left there for two days. The number of emerging adult parasites in each cage was recorded daily (a total number of adults emerged per cage varied from 23 to 195) and the time taken for 50% emergence was calculated from the correlation equation by plotting the cumulative percentage of adults emerged against time. For M. helvolus the mean duration time of the life cycle was estimated to be 19.4 days on scales developed on potato sprouts and 15.1 days on scales developed on N. oleander. For M. affinis stanley the relevant estimates were 18.8 days and 23.4 days, respectively, while for M. lounsburvi the estimates were 21.3 and 18.6 days, respectively. For M. helvolus and M. lounsburyi the duration of the life cycle was shorter when the host insect developed on Nerium plants than on potato sprouts. For M. affinis stanley the reverse was true. These differences show the effect of the host of S. oleae on the time of development of the parasites, possibly reflecting the differences of the scale insect developed on different hosts as food quality for the parasites.
