Self-Recognition and Allorecognition Mechanisms Exert a Significant Influence on the Sex Allocation Patterns of the Pea Aphid [PDF]

open access: yesInsects
The mechanism controlling sex allocation in the pea aphid, Acyrthosiphon pisum (Harris), remains a crucial yet unresolved issue in the field of evolutionary ecology. This study aims to assess the influence of the presence of both self and non-self clones,

The Genetics of Host Plant Acceptance in Pea Aphids. [PDF]

open access: yesMol Ecol
ABSTRACT The evolution of host‐associated sympatric populations in phytophagous insects (so called “host races”) connects adaptive divergence to barriers to gene flow. Pea aphid (Acyrthosiphon pisum) host races specialise on legume species, and because host plant choice leads to assortative mating, the genetic basis of host plant acceptance is key to ...

How a Melanism Mutant Responds to Different Temperatures: A Case Study in Ladybird Beetle <i>Harmonia axyridis</i> Demonstrating Thermal-Induced Phenotypic Plasticity. [PDF]

open access: yesEcol Evol
ml, inherited in a Mendelian autosomal recessive manner, is a novel melanism mutant of Harmonia axyridis. When compared to wt, ml exhibited vastly smaller changes in the occurrence frequencies of dark spots on both the dorsal cuticles of pupa and elytra in response to thermal variations. ml had very high melanin level even at 32.5°C and showed a higher
