Summary: Inquiline ant social parasites exploit other ant species for their reproductive benefit because they do not possess a worker caste. The biology and natural history of inquilines are largely unknown due to their relative rarity in nature. This study shows that inquiline Solenopsis daguerrei likely exists in four genetically distinct groups, each with different degrees of host association. Inbreeding is common in S. daguerrei, presumably a result of intranidal mating and restricted dispersal.

Summary: Plant invasions have significant impacts on ecosystems and human well-being. This study conducted a systematic review and meta-analysis on the genetic diversity of invasive and native plant species. The results showed that invasive populations had lower genetic diversity and higher inbreeding rates compared to native populations. Fragmented and degraded habitats also had lower genetic diversity in invasive species. Polyploid invaders with hybrid capacity had lower genetic diversity as well. Invasive herbs with vegetative propagation were more sensitive to the loss of genetic diversity and had higher levels of inbreeding. Historical processes and clonality were found to influence the genetic diversity in invasive populations.

Summary: This study assessed the efficacy of two bait products, Arino-su-korori and Hyper Arino-su-korori, in controlling the red imported fire ant, Solenopsis invicta. Both baits demonstrated high mortalities of fire ants in laboratory conditions and significantly reduced their foraging activities in the field. Arino-su-korori performed slightly better than Hyper Arino-su-korori in terms of colony elimination and long-term suppression of field fire ants.

Summary: Clonal reproduction allows invasive species to avoid inbreeding depression, giving them an advantage in establishing themselves. The prevalence and significance of the double-clonal reproduction system in the invasive ant, Paratrechina longicornis, remains unclear. Our study found that double clonality is widespread in P. longicornis populations worldwide, suggesting its importance in facilitating global colonization.

Summary: Selenium is an essential trace element for many organisms but exhibits toxic effects at higher doses. Previous studies have shown negative impacts of selenium exposure on various insect orders, but no clear patterns of toxicity between orders or similarities between species within families. Additional research is needed to determine the potential effects of selenium on beneficial insects and its compatibility with biological control agents. This review explores selenium as a potential insecticide and future research directions.

Summary: The western yellowjacket is an important seasonal pest in the western United States. This study aimed to determine the potential of using the isoxazoline fluralaner as a bait toxicant. Microsatellite genotyping revealed at least 27 different colonies foraging at a single monitoring site. Some colonies disappeared after baiting, and new colonies were detected. Minced chicken and hydrogel baits containing fluralaner significantly reduced foraging yellowjackets. Multiple bait applications will be necessary for long-term control.

Summary: This study reports the first confirmed population of the invasive species, the little fire ant, in East Asia, specifically in Taiwan. The little fire ants were found in two locations in central Taiwan, approximately 30 km apart. Genetic and behavioral analyses showed that both populations reproduce clonally and exhibit no aggression towards each other. Population genetic analyses suggest that the two populations are likely derived from a common source or genetically similar populations.
