یکی از زیرخانوادههای نسبتاً بزرگ زنبورهای پارازیتوئید خانوادهی Ichneumonidae، زیر خانواده Ctenopelmatinae، با بیش از 1200 گونهی توصیف شده در سطح جهان است (5). اعضای این زیرخانواده به عنوان پارازیتوئید زنبورهای تخمریز ارهای (Hym.: Symphyta) شناخته میشوند و بعضی گونهها به عنوان عامل کنترل زیستی زنبورهای تخمریز ارهای آفت از اروپا به آمریکای شمالی و کانادا وارد گردیدهاند (4). از لحاظ ریخت...
Spores from three bryophyte species with dwarf males (Homalothecium lutescens, Homalothecium sericeum and Isothecium alopecuroides) were sown on shoots of H. lutescens in vitro. After 10 months, presence and fertility of dwarf plants were scored. Spores of the more distantly related I. alopecuroides were unable to develop into dwarf plants on H. lutescens. Spores of both H. lutescens and H. ser...
Both Salvia akiensis and S. lutescens (Lamiaceae) are endemic to Japan. Salvia akiensis was recently described in 2014 in the Chugoku (= SW Honshu) region, and each four varieties of S. lutescens distributed allopatrically. Among varieties in S. lutescens, var. intermedia show a disjunctive distribution in the Kanto (=E Honshu) and Kinki (= W Honshu) regions. Recent field studies of S. lutescen...
Platycoelia lutescens Blanchard (Scarabaeidae: Rutelinae: Anoplognathini), a species that occurs in the Andes Mountains of South America, is redescribed. Platycoelia albescens (Bates) and P. baronis (Ohaus) are considered new synonyms of P. lutescens. A lectotype is designated for P. albescens. The use of this species as a food source by the people of the Ecuadorian highlands is discussed. RESU...
Differentiation in low temperature resistance was investigated in two closely related species, Drosophila lutescens and D. takahashii. Drosophila flies at various developmental phases from an egg to an adult fly stage were chilled by low temperature of -3°C for six hours and the percent of hatching or hatchability for eggs, the percent of emergence for nonadult individuals and the percent of fl...
The X and Y sex chromosomes of placental mammals show hallmarks of a tumultuous evolutionary past. The X Chromosome has a rich and conserved gene content, while the Y Chromosome has lost most of its genes. In the Transcaucasian mole vole Ellobius lutescens, the Y Chromosome including Sry has been lost, and both females and males have a 17,X diploid karyotype. Similarly, the closely related Ello...
Chloroplast pigments from young and old leaves of three chlorophyll-deficient peanut mutants (lutescens, auredus, and virescent) and two "normal" peanut genotypes ('Chico' and 'Guanajuato') were analyzed using high performance liquid chromatography. All genotypes showed chlorophylls a and b, carotene, lutein, neoxanthin, and violaxanthin in young and old leaves. Generally, there were decreases ...
A large mole vole from the early Middle Pleistocene of Armenia shows morphological features and hyposodonty intermediate between basal Early Pleistocene E. tarchancutensis and the late Middle Pleistocene to Recent southern mole vole E. lutescens. The occlusal morphology of the first lower molar is similar to Early Pleistocene forms but hypsodonty values do not overlap either with Early Pleistoc...
Helminthosporium (Bipolaris) causes a leaf spot disease in Chrysalidocarpus lutescens (cane palm) in Sri Lanka. The losses could reach 90% of production during rainy weather conditions. Field experiments were carried out to test the efficacy of treatment of seeds of C. lutescens against Helminthosporium infection. In the fungal growth tests the isolates T.harzianum 1, T.harzianum 2, T.viride 1,...
