SummaryPhenology and parasitism of the scale insect, Coccus pseudomagnoliarum (Kuwana) (Hemiptera: Coccomorpha: Coccidae), infesting Citrus sinensis (Rutaceae), were studied in Papagou area, in northeastern Athens, from June 2015 to June 2017. Coccus pseudomagnoliarum is a univoltine, viviparous, parthenogenetic species. It overwintered as settled 1st instar nymph on the shoots of the trees. The 2nd instar nymphs appeared between the beginning of April and the end of May, and the mature females were recorded from the beginning of May until the middle of June. The crawlers appeared between the middle of May and the middle of June and the 1st instar nymphs settled on the shoots at the end of May, where they remained during the whole summer period, winter, until the beginning of April next year. Parasitism of the scale was recorded between the beginning of May and the middle of May and reached a maximum rate of 35%. The recorded parasitoid species were Coccophagus shillongensis Hayat and Singh (Hymenoptera: Aphelinidae), Coccophagus spp. and Metaphycus dispar (Mercet) (Hymenoptera: Encyrtidae).

In the presented studies the genotypes of 46 varieties of red currant (Ribes rubrum) from the All-Russian Research Institute of Fruit Crops Breeding (VNIISPK) the collection were studied for 14 microsatellite locus. The data were obtained by the detection method of – fragment analysis using capillary electrophoresis. Varieties with rare, unique alleles and combinations of alleles have been identified. In most cases, no more than two fragments were identified for each genotype for a specific locus, but three fragments at some loci were amplified in the samples (Orlovchanka, Konstantinovskaya, Nadezhda – e3-B02; Marmeladnitsa – g2-G12; Nadezhda – g2-J08; Svetlitsa, Tatianina – g1-L12). The profiles of the cultivars Cascad and Red cross are identical to each other, although they differ from the others. The Red cross [(Cherry × White Grape] and Cascad [(free pollination of the variety Diploma (Cherry × White grape)]] varieties were developed in the USA and have common ancestors. It can be assumed the collection under different names contains the same genotype or that these pairs of varieties are so similar that the polymorphism of the analyzed loci is not enough to distinguish them. To prevent a shift in the size of alleles control varieties were selected and proposed, zoned in the territory of the Russian Federation – Gazelle (originator of VNIISPK: Chulkovskaya × Maarses Prominent) and Valentinovka (originator of VNIISPK: Rote Shpetlese × Jonker van Tets). The data obtained on the polymorphism microsatellite loci Red currant can be used for further identification.

Cnemidophorus Uniparens

Parthenogenetic species of lizard occasionally produce male progeny characterized by developmental defects and low viability. Production of anomalous males is an unresolved problem in sexual differentiation as parthenogenetic female lizards are expected to produce female offspring. The "anomalous male" phenomenon was examined by sexing nonviable embryos produced by the parthenogenetic whiptail lizard Cnemidophorus uniparens. Twenty-six deformed embryos were obtained; all were female except for three which did not possess gonads. Male embryos were not detected. Developmental deformities found in Cnemidophorus embryos included anophthalmia, micropthalmia, encephalocoele, hypoplasia of the lower jaw, head foreshortening, gastroschisis, and malformations of the vertebral column. Several embryos possessed a combination of defects. Four hypotheses are presented to account for production of anomalous males by reptilian parthenoforms. Three hypotheses involve production of sex-reversed males (genetic females). A fourth hypothesis asserts that anomalous males are derived from hybridization events between a female from a unisexual species and a male from a bisexual species. Of the four hypotheses, the hybridization hypothesis has the greatest utility in explaining production of anomalous males by parthenogenetic lizards.
