THE EXTERNAL MORPHOLOGY OF KALLITAMBINIA AUSTRALIS MUIR (HOMOPTERA: TROPIDUCHIDAE)

اثرات مقادیر زیر کشنده (LC25) اسانس رازیانه و پونه روی پارامترهای زیستی زنجرک خرما Ommatissus lybicus (Homoptera: Tropiduchidae)

زنجرک خرما Ommatissus lybicus یکی از آفات مهم خرما در بسیاری از نقاط جهان و ایران است. برای کنترل این آفت در نواحی که آلودگی بالا است از آفت‌­کش­‌ها استفاده می­‌شود. باتوجه به خطر آفت‌­کش­‌ها، مطالعه در مورد  جایگزین­‌های بی‌خطر ضروری به­ نظر می­‌رسد. هدف از این مطالعه ارزیابی اثرات زیر کشنده (LC25) اسانس گیاهان پونه و رازیانه روی پارامترهای جدول زندگی زنجرک خرما با استفاده از جدول زندگی دوجنسی...

Morphology and Ultrastructure of the Convoluted Gland in the Ant Dinoponera Australis (hymenoptera : Formicidae)

The morphology and fine structure of the convoluted gland inside the venom reservoir of the ponerine ant Dinoponera austrafis (Hymenoptera : Formicidae) are described. The cells of the convoluted gland can be divided into 3 major groups: (1) epithelial cells, (2) glandular cells with end apparatus secreting into the tubule inside the convoluted gland, and (3) glandular cells with end apparatus ...

The Phylogeny of the Homoptera

External morphology of the spicules of some Trichodoridae.

External morphology of spicules in several species of Trichodoridae was studied by scanning electron and light microscopy. The bristles on the spicules observed in the light microscope in several species were revealed as small scales forming a sheath which covers most of the spicule body. Some species have smooth spicules, whereas other species exhibited complicated structures formed by project...

Morphology and spectral absorption characteristics of retinal photoreceptors in the southern hemisphere lamprey (Geotria australis).

The morphology and spectral absorption characteristics of the retinal photoreceptors in the southern hemisphere lamprey Geotria australis (Agnatha) were studied using light and electron microscopy and microspectrophotometry. The retinae of both downstream and upstream migrants of Geotria contained two types of cone photoreceptor and one type of rod photoreceptor. Visual pigments contained in th...
