Small to very large species (6-42 mm); generally concolorous, rarely with conspicuous markings; predominantly micropterous and
apterous forms.
Usinger & Matsuda 0959: 200) gave a key to the 10 known
apterous American genera of Mezirinae.
In both the greenhouse and the field, we found that
apterous strawberry aphids moved among plants.
Each experimental unit was infested with 10
apterous adult aphids, which were confined in individualized tubular cages (15 cm in diameter by 61 cm in height) constructed of transparent plastic (Makrolon Tuffak Lexan) covered with organdy cloth.
A fairly similar distribution exists in the Tabariini, a small group of three currently monospecific genera of
apterous and very long-legged katydids of spider-like appearance, the only South American representatives of the otherwise Old World subfamily Mecopodinae.
Many species of Ptilomerinae are only known from
apterous morphs; macropterous forms are rare and often dealate (Chen et al.
Twenty
apterous aphids (third or fourth instars) were removed with a fine brush from a leaf of infested pepper plants on which they were reared and placed on the pepper leaf disks in small Petri dishes lined with moistened cotton under the pepper leaf for each concentration.
Aristotle's mnemonic tokens functioned indeed like sunglasses but then what Reformation's winds facilitating the adaptation of
apterous fly did was without precedent: throw glasses away and give up any mental representation at all.
Each group carefully transferred four
apterous (wingless) adult aphids from stock plants to each of their plants with an eyelash brush.
Aphids' life cycles are very intricate and can imply both sexual and asexual reproduction as alate and
apterous forms (Nieto Nafria et al.
Diuraphis aizenberg (Homoptera: Aphididae): Key to
apterous viviparous females, and a review of Russian language literature on the natural history of Diuraphis noxia (Kurdjumov, 1913).
Water content, weight change, and activity of
apterous and alate virginoparous Acyrthosiphon pisum (Harris) (Homoptera: Aphididae).
