Summary: This article discusses the important evolution of mandibles in insects, particularly the highly modified mandibles in parasitoid chalcid wasps. The authors suggest that this evolution plays a significant role in insect diversification, helping them adapt to parasitize hosts hidden in hard substrates.

Summary: Two new species of Coniopterygidae, Semidalis procurva sp. nov. and Semidalis tibetana sp. nov., have been discovered in China. In addition, the first record of Semidalis decipiens (Roepke, 1916) in China was made. An identification key for adult males of the Chinese Semidalis Enderlein, 1905 has also been developed.

Summary: Two new species of Coniopterygidae, Coniopteryx (Coniopteryx) tenuisetosa sp. nov. and Coniopteryx (Coniopteryx) serrata sp. nov., are described from China, with detailed characterization of male genitalia differences and the first record of Coniopteryx (Coniopteryx) alticola Sziraki, 2002 in China. Additionally, a key to species of the genus Coniopteryx from China is provided.

Summary: This study discovered that two trehalase genes, SlTre1 and SlTre2, were highly expressed in the third instar larvae of Spodoptera litura after being parasitized by Meterous pulchricornis. Silencing these genes in parasitized larvae resulted in a significant decrease in trehalase activity and glucose content. Furthermore, the fitness of parasitoid offspring was negatively affected. These findings suggest that parasitoid wasps can regulate trehalase expression in host larvae to support the development of their offspring.

Summary: Using Leptopilina boulardi as a model, this study investigated the function of vitellogenin receptor (VgR) in parasitoid wasps. The results showed that LbVgR had high expression in the head but lower expression in the ovary. It was found that LbVgR had no effect on ovary development, but played a role in host-searching and mating behavior. Transcriptome analysis revealed that LbVgR might regulate the expression of important chemoreception genes to adjust parasitoid behaviors.

Summary: This study evaluated the effect of phylogenetic (and taxonomic) signals of plants and host species on parasitoid host range. The results indicated the importance of phylogenetic (or taxonomic) signals in dictating parasitoid host specificity. Identifying these signals could be useful for biological control programs.

Summary: Five new gall wasp species have been discovered in Lorestan, Iran, including Aulacidea koeiana Melika, Tavakoli & Stone, sp. nov., A. lorestanica Melika, Tavakoli & Stone, sp. nov., A. piroziae Melika, Stone & Pujade-Villar, sp. nov., Phanacis strigosa Melika, Stone & Tavakoli, sp. nov., P. tavakolii Melika, Stone & Pujade-Villar, sp. nov. Descriptions, diagnoses, and information on biology and host associations are provided for all new species, and the male of Isocolus beheni Melika & Karimpour, 2008 is described for the first time.

Summary: The study reveals the crucial role of Orco genes in the mating and host-searching behaviors of parasitoid wasps. This is the first characterization of Orco gene functions in parasitoid wasps, which contributes to a better understanding of the chemoreception basis of parasitoid wasps and the development of advanced pest management strategies.

Summary: This study presents the first confirmed record of Halyomorpha picus in Pakistan, along with providing detailed information on the species and proposing two new junior subjective synonyms. Furthermore, it corrects misidentifications of the species in Pakistan and points out a misidentification of H. picus in Egypt as H. halys, extending the distribution of the invasive species to North Africa.

Summary: Cryptic species diversity is a major challenge in parasitoids attacking oak gall wasps due to sexual dimorphism, morphological plasticity, small size, and poorly known biology. The study reveals that parasitoid wasps have adaptations allowing them to exploit specific host trait combinations and prefer larger galls. These findings have implications for evolutionary ecology and biocontrol, supporting the tritrophic niche concept in plant-herbivore-parasitoid communities.

Summary: The study found that Cotesia congregata parasitoid wasp performs poorly under high temperature stress compared to the Manduca sexta host. It also indicates that the growth of both host and parasitoid is influenced by various factors under different temperatures.

Summary: A new genus of caponiid spider, Aamunops gen. n., is described and its phylogenetic placement is tested using morphological data. The genus includes four species collected in Veracruz, Mexico. The study confirms the monophyly of Aamunops gen. n. and adds new character states to the published dataset. Additionally, a new spider species, Orthonops confuso sp. n., is described and its phylogenetic affinities are discussed.
