Transgenerational effects and temperature variation alter life history traits of the moon jellyfish

An evolutionary ecology perspective, dissecting 10 asexual generations of Aurelia coerulea polyps provides insight into the necessity of sexual reproduction in organisms involving a metagenic life cycle, i.e., to renew the asexual reproduction ability of a population.

A Star Polyamine-Based Nanocarrier Delivery System for Enhanced Avermectin Contact and Stomach Toxicity against Green Peach Aphids

The stomach and contact toxicity of AVM/SPc complex also increased along with the increasing SPc mass ratio, which could be attributed to the enhanced systemic transportation in plants, enlarged contact area to insect pests and stronger permeability across the insect cuticle.

Nanocarrier-Loaded Imidaclothiz Promotes Plant Uptake and Decreases Pesticide Residue

A nano-delivery system for imidaclothiz is constructed, which can not only increase the effective utilization of pesticides, but also decrease the pesticide residue.

A nanocarrier pesticide delivery system with promising benefits in the case of dinotefuran: strikingly enhanced bioactivity and reduced pesticide residue

The theory that the benefits of SPc-delivered pesticide are not only the enhanced bioactivity toward insect pests but also the reduced residue in plants is supported.



Deciphering reproductive polyphenism in aphids

A physiological model of the determination of sexual vs. asexual reproduction in aphids is proposed and viewed from the perspective of newly initiated molecular studies.

Aphid polyphenisms: trans-generational developmental regulation through viviparity

The acquisition of viviparity in Aphididae is considered to be the basis for maternal regulation of these polyphenisms, and through which environmental cues can be transferred to developing embryos through the physiological state of the mother.

Shifting from clonal to sexual reproduction in aphids: physiological and developmental aspects

How environmental cues orientate the reproductive mode of aphids from signal perception to endocrine regulation is discussed, and a comparative analysis of sexual and asexual gametogenesis and embryogenesis is proposed, which has been possible due to the development of molecular methods.

Coexistence in space and time of sexual and asexual populations of the cereal aphid Sitobion avenae

A clear shift between northern and southern populations is found, with decreasing sexuality southwards, and results suggest that other selection pressures could interact with winter climate to determine the local life cycle polymorphism in S. avenae populations.

Juvenile hormone titre and related gene expression during the change of reproductive modes in the pea aphid

Using liquid chromatography‐mass spectrometry in the pea aphid, JHIII titre was shown to be lower in aphid producing sexual morphs under short‐day conditions than in aphids producing parthenogenetic morphs in response to short photoperiods.

The Evolution of Aphid Life Cycles

The life cycles of aphids are among the most remarkable of any animal group. They include parthenogenetic and sexual generations, elaborate polyphen­ isms, and obligate shifting between unrelated

Temporal habitat variability and the maintenance of sex in host populations of the pea aphid

It is proposed that temporal habitat variability exerts a selective pressure to maintain the sexual reproduction in A. pisum through the influence of local habitat characteristics on regional coexistence of reproductive modes in the pea aphid.

Gene Expression Analysis of Parthenogenetic Embryonic Development of the Pea Aphid, Acyrthosiphon pisum, Suggests That Aphid Parthenogenesis Evolved from Meiotic Oogenesis

It is suggested that parthenogenetic oogenesis evolved from a meiosis- like, and not a mitosis-like, process and that the aphid reproductive polyphenism may involve a modification of Spo11 gene activity.
