Respiratory metabolism of the pea aphid, Acyrthosiphon pisum (Hemiptera: Aphididae)
European Journal of Entomology, 2012 The respiratory metabolism of different polyphenic forms of the pea aphid, including wingless and winged asexual females (virginoparae), sexual females (oviparae) and winged or wingless adult males, was investigated using a micro-respirographic method ...

The grapevine aphid Aphis illinoisensis : a good example of recent invasion and rapid colonization by aphids [PDF]
, 2011 Aphis illinoisensis represents one of the most recent aphid invaders from the New World to the Mediterranean Region. This aphid, which is native to North America and is now widely distributed in Central and South America, was first found in Southern ...

The effect of choice and no-choice access on host (Aphis fabae) instars preference, in different ages and sizes of Lysiphlebus fabarum (Hymenoptera: Braconidae: Aphidiinae) [PDF]
نامه انجمن حشرهشناسی ایران, 2016 The influence of parasitoids on population dynamics is affected by host instar preference. The preference pattern of host instars is not fixed and is modified by the availability and relative abundance of host instars, intensity of defensive behaviors in

Developmental expression of Ap-Vas proteins in aphids and flies reveals their evolutionary roles in insects. [PDF]
Insect Mol BiolDuplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Bulletin of Entomological Research, 1920 Head and thorax dark; abdomen pale, apparently pale green, with dark lateral spots. Antennae, cauda and cornicles dark. Legs with mid and hind femora dark, front pair paler; apices of tibiae and the tarsi dark. Antennae shorter than body, rather thick; basal segment larger and paler than second; third much longer than fourth and about as long as the ...

Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent
