The spread of satellite DNAs in euchromatin and insights into the multiple sex chromosome evolution in Hemiptera revealed by repeatome analysis of the bug Oxycarenus hyalinipennis

Insect Molecular Biology, Volume 32, Issue 6, Page 725-737, December 2023., 2023
The genomic analysis revealed a male‐biased abundance of satellite DNAs (satDNAs) in the bug Oxycarenus hyalinipennis. The complementary chromosomal analysis by fluorescence in situ hybridization supported the notion of satDNA enrichment on the Y chromosome of the species.

Complete metamorphosis and microbiota turnover in insects

Molecular Ecology, Volume 32, Issue 23, Page 6543-6551, December 2023., 2023
Abstract The insects constitute the majority of animal diversity. Most insects are holometabolous: during complete metamorphosis their bodies are radically reorganized. This reorganization poses a significant challenge to the gut microbiota, as the gut is replaced during pupation, a process that does not occur in hemimetabolous insects.

A review to the methods of personality measurements in wild animals 野生动物个性测量方法的综述

Wildlife Letters, Volume 1, Issue 3, Page 131-142, September 2023., 2023
One of the challenges in animal personality study is finding a suitable method to measure personality. Here, we outlined three methods (traits rating, behavioral coding, and experimentation) used in animal personality measurement. We found that traits rating was commonly used to test large‐sized animals (e.g., primates), behavioral coding was conducted

Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

Biological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023
ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.

Bioanalogues oj juvenile hormones and intestines mycoflora of some insects

Acta Mycologica, 2014
The subject of this paper is the influence of JH bioanalogues on the mycoflora of intestines of three species of inscets: Dysdereus cinaulams, Pyrrhocoris apterus and Tenebrio molitor. The results are presented in tables.

Sex roles and sex ratios in animals

Biological Reviews, Volume 98, Issue 2, Page 462-480, April 2023., 2023
ABSTRACT In species with separate sexes, females and males often differ in their morphology, physiology and behaviour. Such sex‐specific traits are functionally linked to variation in reproductive competition, mate choice and parental care, which have all been linked to sex roles.

Time measurement in insect photoperiodism: The role of photophase duration and light intensity

European Journal of Entomology, 2022
The initial stages of diapause induction - as summer gives way to autumn - involve a process of time measurement in which the duration of daylength (or nightlength) is determined by a photoperiodic 'clock' based upon the circadian system. In many insects

Insulin peptides and their receptors regulate ovarian development and oviposition behavior in Diaphorina citri

Insect Science, Volume 30, Issue 1, Page 95-108, February 2023., 2023
After female D. Diaphorina citri feed on young shoots, DcILP1, DcILP2, and DcIR in the insulin signaling system are upregulated. Interfering with these three genes reduces the expression level of DcRheb in the target of rapamycin signaling system and the reproduction‐related gene DcVg.

Pre-diapause mating and overwintering of fertilized adult females: New aspects of the life cycle of the wing-polymorphic bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

European Journal of Entomology, 2010
New aspects of the life-cycle of the flightless wing-polymorphic bug Pyrrhocoris apterus (L.) are described. It was found that 1.1-14.9% of the adult females of P. apterus in 11 samples collected from 4 populations in the South Bohemia had mated prior to

Viral discovery and diversity in trypanosomatid protozoa with a focus on relatives of the human parasite Leishmania. [PDF]

, 2018
Knowledge of viral diversity is expanding greatly, but many lineages remain underexplored. We surveyed RNA viruses in 52 cultured monoxenous relatives of the human parasite <i>Leishmania</i> ( <i>Crithidia</i> and <i> ...
