Defensive Behaviors Of The Mealybug Nipaecoccus Nipae (Maskell, 1893) (Hemiptera: Pseudococcidae) And The Green Lacewing Ceraeochrysa Claveri (Navás, 1911) (Neuroptera: Chrysopidae), With Videos Of Dorsal Packet Loading And Mealybug Ostiole Function, Erin C. Powell

Insecta Mundi

The interactions between the lacewing Ceraeochrysa claveri (Navás) (Neuroptera: Chrysopidae) larva and the coconut mealybug Nipaecoccus nipae (Maskell) (Hemiptera: Pseudococcidae) were recorded. The third-instar lacewing larva constructed a dorsal packet using mealybug wax from both male pupal cases and the bodies of adult females. Surprisingly, live nymphs were also frequently placed into the dorsal packet. Prey mealybugs were discarded and not incorporated into the packet after consumption. When disturbed, adult female mealybugs reflex bled from their dorsal ostioles, contacting the mouthparts of the lacewing. The lacewing quickly retreated to clean the mouthparts on the substrate, providing further evidence that ostiolar …

Predicting The Potential Distribution In South Korea Of Two Mealybug Species (Hemiptera: Pseudococcidae) Intercepted On Pineapples In Quarantine, S Bin Kim, Soo-Jung Suh

Insecta Mundi

Dysmicoccus brevipes (Cockerell) and Dysmicoccus neobrevipes Beardsley are major pests of pine­apples, ornamentals, and vegetable crops in many countries around the world. The potential distribution of these mealybug pests into South Korea remains a prime concern because of their high incidence in intercep­tions screened during inspection. Hence, these species prompted a modelling effort to assess their potential risk of introduction. Potential risk maps were developed for these pests with the CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s is projected based on the RCP …

Can The Vegetation Structure And Composition In Urban Green Spaces Determine Diversity Of Green Lacewings (Neuroptera: Chrysopidae)?, Jose I. Martinez, Raiza J. Castillo, Adrián Ardila-Camacho, Charles V. Covell, José Isabel López-Arroyo, Francisco Javier Nava-Guízar

Insecta Mundi

Green spaces represent the only natural areas in several cities around the world, providing good shelters for the local fauna. Based on this premise, many ecological studies have been conducted focused on these areas. Most of these works are about insects, particularly butterflies and beetles. Our study is centered on a different group: green lacewings (Neuroptera: Chrysopidae). These insects exhibit a similar feeding behavior to some other groups, such as beetles. We estimated diversity, richness, distribution, abundance and similarity employing two methods: sweep netting and suction trapping. Also, oviposition hosts were identified in 20 different green spaces. Approximately 740 specimens …

Genomics-Based Taxonomic Rearrangement Of Achlyodini And Carcharodini (Lepidoptera: Hesperiidae: Pyrginae), Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

Insecta Mundi

Genomic analysis of Pyrginae Burmeister, 1878 (Lepidoptera: Hesperiidae Latreille, 1809) with an emphasis on the tribes Achlyodini Burmeister, 1878 and Carcharodini Verity, 1940 reveals many incon­sistencies between the resulting phylogeny and the current classification. These problems are corrected by proposing new taxa, changing the ranks of others, or synonymizing them, and transferring species between genera. As a result, five subtribes, one genus, 20 subgenera, and one species are proposed as new: Cyclo­semiina Grishin, new subtribe (type genus Cyclosemia Mabille, 1878), Ilianina Grishin, new subtribe (type genus Iliana E. Bell, 1937), Nisoniadina Grishin, new subtribe (type genus Nisoniades Hübner, [1819]), …

The Pepsis Menechma Lepeletier (Hymenoptera: Pompilidae: Pepsinae) Taxonomic And Nomenclatural Problem, Frank E. Kurczewski

Insecta Mundi

Hurd (1952), in revising the Nearctic species of Pepsis Fabricius, separated P. cerberus Lucas from P. elegans Lepeletier based on external morphology and geography. Vardy (2005), in his Western Hemisphere Pepsis revision, combined these taxa and several Neotropical color and structural variants in a broad defini­tion of P. menechma Lepeletier extending across ~11,250 km and two continents. Vardy (2005) synonymized the familiar and well-documented, 160-year-old P. elegans under P. menechma probably because it appeared several pages later in Lepeletier’s (1845) Histoire Naturelle des Insectes. Hyménoptères. Vardy’s (2005) interpre­tation of Pepsis menechma as a viable species presents a taxonomic and …

Insecta Mundi

Size equivalence, seasonal synchronicity, geospatial sympatry, habitat specificity, and host-search­ing behavior implicate the spider wasp Chalcochares hirsutifemur (Banks) (Hymenoptera: Pompilidae: Pompilinae) as an obligate parasitoid on species of the wafer-lid spider genus Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae) on coastal sandy back dunes in San Luis Obispo and Santa Barbara coun­ties, CA. This is substantiated by 2010–2022 macrophotographs, videos, and field observations. Such host evidence supports recent unpublished phylogenomic studies that place Chalcochares as a sister genus of the spider wasp tribe Aporini, in which all species are known obligate parasitoids on trapdoor spiders and related Mygalomorphae.
