The sexuales of Thelaxes suberi (Hemiptera, Aphidoidea: Thelaxinae).
The oviparous female and male of Thelaxes suberi (del Guercio) are described and illustrated in detail for the first time. Notes on distribution, biology and host plants are presented, and keys are provided to the known sexuales of European Thelaxes species.
متن کاملمدلهای نمونهبرداری دنبالهای و بینومیال شته (del Guercio) Sipha elegans (Hemiptera: Aphididae) در مزارع گندم آبی شهرستان میانه
در این پژوهش پراکنش فضایی شته (del Guercio) Sipha elegans تعیین و مدلهای نمونه-برداری دنبالهای و بینومیال برای پایش آن در مزارع گندم آبی منطقه میانه تهیه شد. برای نمونهبرداری، هر سه روز یکبار 100 ساقه گندم بازدید و میانگینها و واریانسهای جمعیت برای تخمین آمارههای پراکنش فضایی استفاده شدند. با توجه به مناسبتر بودن روش تیلور، از پارامترهای آن برای تهیه مدلها در دو سطح دقت تحقیقاتی (1/...
متن کاملDNA barcodes to identify species and explore diversity in the Adelgidae (Insecta: Hemiptera: Aphidoidea).
The Adelgidae are relatively small, cryptic insects, exhibiting complex life cycles with parthenogenetic reproduction. Due to these characteristics, the taxonomy of the group is problematic. Here, we test the effectiveness of the standard 658-bp barcode fragment from the 5'-end of the mitochondrial cytochrome c oxidase 1 gene (COI) in differentiating among 17 species of Adelgidae, in associatin...
متن کاملMorphological Response of Eight Quercus Species to Simulated Wind Load
Leaf shape, including leaf size, leaf dissection index (LDI), and venation distribution, strongly impacts leaf physiology and the forces of momentum exerted on leaves or the canopy under windy conditions. Yet, little has been known about how leaf shape affects the morphological response of trees to wind load. We studied eight Quercus species, with different leaf shapes, to determine the morphol...
متن کاملComparative Pollen Morphological Analysis and Its Systematic Implications on Three European Oak (Quercus L., Fagaceae) Species and Their Spontaneous Hybrids
Pollen morphology of three parental Quercus species (Q. robur L., Q. petraea (Matt) Liebl, Q. pubescens Willd.) and two spontaneous hybrids of these species (Q. ×calvescens Vuk. = Q. petraea × Q. pubescens and Q. ×rosacea Bechst. = Q. robur × Q. petraea) was investigated in this study. The pollen originated from 18 natural oak sites and 67 individuals (oak trees). Each individual was represente...
