Summary: Delaying mating has negative effects on the reproduction and population life table parameters of Henosepilachna vigintioctopunctata, leading to reduced preoviposition and oviposition periods in adults, decreased mating success rate, fecundity, fertility, and proportion of hatching eggs, as well as increased population doubling time. This study provides important information for potential pest control strategies in the future.

Summary: Mating disruption is an effective method for pest management, but delayed mating has limited impact on the reproductive fitness of the willow leaf beetle Plagiodera versicolora Laicharting. Additionally, mating age is an important factor affecting mating selection, sexual performance, and fecundity in P. versicolora.

Summary: Multiple matings in Ophraella communa were found to increase female fecundity and ovary egg deposition. Carboxypeptidase B (OcCpb) and carbonic anhydrase (OcCa) genes were identified as key SFP genes in the reproductive process, as their expression was upregulated in the bursa copulatrix of mating females.

Summary: The study reveals that female Aedes aegypti mosquitoes become sexually receptive 1 day after emergence, but can ingest blood much sooner. There are differences in fertility between young and old females, with significant declines observed in fertility of old females after 2 weeks.

Summary: This study investigated the reproductive investment of N. californicus males under limited prey availability. The results showed that males could still mate after a 36-hour fast, but the mating duration increased. If the daily food availability was below 20% of demand, males could mate until the end of their lives, but their fertility decreased gradually.

Summary: Cryptic male mate choice refers to the differential allocation of resources by males to females during or after copulation. In the fruit fly Drosophila melanogaster, males mate longer and allocate more resources to larger females compared to smaller females. However, it is unclear if this increased investment in larger females has any impact on the males' subsequent matings.

Summary: The research indicates that a single exposure to cold stress can reduce the mating success of male crickets, but after some chemosensory contact with a female, most males were able to produce spermatophores and mate successfully.

Summary: This study found that male Orius laevigatus have a high capacity for consecutive mating in mass-rearing, and fecundity changes with male and female age. While fecundity is influenced by female age and mating status, little is known about the impact of parental status at mating on female reproductive outcomes in BCAs for efficient mass-rearing and field performance.

Summary: This study investigated the benefits of copulation with large males in the firebug species, Pyrrhocoris apterus. The results showed that increasing male body size did not have a positive effect on the reproductive characteristics of females. Several reasons for this deficiency were discussed.

Summary: Individual differences in male reproductive success impact genetic drift and natural selection, changing genetic variation and trait distributions in future generations. The study introduces a hierarchical probability model to explore determinants of male reproductive success, showing that factors beyond tree size also play a role. Simulations demonstrate the method's superiority in explaining male fecundity.

Summary: The widespread occurrence of extra-pair paternity in birds adds complexity to our understanding of sexual selection and mating system evolution. In the case of lark buntings, male seeking behaviors for extra-pair paternity are overt and conspicuous, while females resist these attempts. Male plumage traits predict male effort in seeking extra-pair paternity and correlate with fitness gained through it.

Summary: Previous studies have found that successive matings in male spiders can lead to a decrease in copulatory behaviors and the number of sperm transferred, but do not affect the duration of courtship or mating. Additionally, genital copulatory courtship varies with male size, while non-genital copulatory courtship decreases over successive matings.

Summary: The study identified a takeout gene, named Bdtakeout2, highly expressed in the male accessory glands of Bactrocera dorsalis, playing a critical role in male mating behavior and fertility. Treatment with exogenous hormones and photoperiod exposure influenced the expression of Bdtakeout2, affecting male mating success and female fertility.

Summary: Malassezia furfur is a common commensal member of human/animal microbiota that is also associated with several pathogenic states. Recent studies report the involvement of Malassezia species in Crohn's disease, pancreatic cancer, and cystic fibrosis. A recent genomics analysis revealed the existence of hybrid isolates and identified their putative parental lineages, showing the occurrence of multiple hybridization events in the species' evolutionary trajectory.

Summary: In this study, the researchers found that mating induced sex-specific behavioral and transcriptional changes in both genders of Spodoptera frugiperda. The study showed that mating led to a decrease in calling or courting behavior in both females and males, and females did not lay eggs until the day after the first mating. The analysis of gene expression revealed that mating induced upregulation of reproductive-related genes in females, while in males, mating did not have a significant effect on reproductive processes.

Summary: The study compared the life performance and mating choice of Spodoptera litura reared on different diets, showing significant effects on developmental stages, fecundity, and mate choice. Artificial diet may promote behavioral isolation, impacting mating outcomes. Host plant preference during the larval stage may shape phenotypic plasticity and behavioral isolation in S. litura populations.
