A new nematode, Tripius gyraloura n. sp., is described from the arundo gall midge, Lasioptera donacis Coutin (Diptera: Cecidomyiidae). This gall midge is being considered as a biological control agent for use in North America against the introduced giant reed Arundo donax (L.) (Poaceae: Cyperales). Thus the present study was initiated to investigate a nematode parasite that was unknown at the time studies with L. donacis were initiated. The new species has a rapid development in the fly host and the mature parasitic female nematodes evert their uterine cells in the hosts' hemolymph. Because large numbers of nematodes sterilise the host, eradication of the parasite from laboratory colonies of the midge may be necessary before populations of the fly are released.

Ficus glomerata, commonly known as the cluster fig tree, is a key component of tropical ecosystems, providing essential ecological services and serving as a crucial habitat for various fauna. This review focuses on the diverse array of parasites associated with Ficus glomerata, exploring the intricate host-parasite interactions that shape the ecological dynamics of this plant species. The study encompasses a thorough examination of the different types of parasites affecting Ficus glomerata, including insects, fungi, nematodes, and other pathogens. Special attention is given to the life cycles, modes of transmission, and the impact of these parasites on the health and reproductive success of the host tree. Additionally, the role of environmental factors and climate conditions in influencing parasite prevalence and distribution is discussed. Understanding the complex relationships between Ficus glomerata and its parasites has broader implications for ecosystem management, conservation, and agricultural practices. The review emphasizes the importance of considering these interactions in the context of biodiversity conservation and sustainable land use. Furthermore, potential strategies for mitigating the negative effects of parasites on Ficus glomerata, such as integrated pest management and ecological restoration, are explored. A pair of parasites There are records of seven predators and one pathogen on it. In addition to this one, hyperparasites are also discovered, which lowers the parasite's ability to regulate its own biocontrol efficacy. Using a tube, the larva of Bracon sp. attaches itself to the abdomen of the fifth instar nymph, feeding on its abdominal contents and ultimately causing its death. The recorded parasitization rate ranged from 4 to 45%. The bracon species is hyperparasitized by a black eulophid wasp and parasitization rate between 2 and 15% of the time. Furthermore, a third instar nymph of P. depressa is parasitized by an unidentified endoparasitic encyrtid wasp. It lays its eggs inside the host's body, and once it has eaten through the host's bodily tissue, its larva mummyfies the host and pupates inside of it. By making a hole in the mummy and hiding behind the meconium and empty shell, the adult emerges. The percentage of parasitization ranged from 5 to 92%. P. depressa's predators include common mynah (Acridotherus tristis), red bunted bulbul (Pycnonotus cafer), thrip (Cercothrip tibialis), spider (Aranarus tristis), and an unidentified red mite. Additionally, Formicid ants of Camponotus sp. and Enictus sp. prey mantis (Hierodula sp. It has also been noted that the pathogen Aspergillus flavipus infests nymphs and galls. Some of these biocontrol agents, such as bracon species and encyrtid wasps, may be mass-produced in the lab and released into the field to monitor P. depressa populations. These agents are crucial in managing the P. depressa population.

First report of a mermithid nematode infecting the invasive Megacopta cribraria (Hemiptera: Plataspidae) in the United States2015 •
Megacopta cribraria (Hemiptera: Plataspidae) has become a pest of soybean, Glycine max (L.), in the United States. While several natural enemies of M. cribraria have been reported, our study is the first to report nematodes beneath the pleural membranes in the abdominal cavities of adults. Morphological and molecular analyses suggest this nematode belongs to the family Mermithidae. This first report of a nematode infection in M. cribraria adds to the current inventory of enemies attacking this insect. Our observations provide a basis for future research to examine the impact of nematodes on M. cribraria mortality and to investigate their capacity to reduce populations.

The gall fly, Fergusonina lockharti Tonnoir (Diptera: Fergusoninidae) and description of its associated nematode, Fergusobia brittenae sp. nov. (Tylenchida: Neotylenchidae)Fergusonina lockharti Tonnoir (Diptera: Fergusoninidae), which forms apical leaf bud galls on Eucalyptus camaldulensis in a mutualistic association with a nematode, is redescribed, and a description is provided for the new species of its associated nematode, Fergusobia brittenae sp. nov. All life stages, egg, larva, female and male, of F. lockharti, and parthenogenetic female, infective preparasitic female, parasitic female and male of Fb. brittenae sp. nov. are described. Notes on the biology of the fly/nematode association are provided. Fergusonina lockharti is characterized by its large gall size and larva with a dorsal shield with four prominent anteriorly projecting sclerotized teeth. Fergusobia brittenae sp. nov. is characterized by having strongly C-shaped parthenogenetic females with narrow tails one and a half to twice as long as wide, and J-shaped males with a short broad tail with a broadly rounded tip, a short bursa and angular spicules with a large manubrium.

The smokybrown cockroach Periplaneta fuliginosa has spread all over the world, and is now one of the most undesired invasive alien pests in Japan. Because cockroaches are generally infected by thelastomatid nematodes, they are being distributed around the world with their parasitic nematodes. Nothing is known about parasitic nematode species in P. fuliginosa differences, or similarity of the parasite’s population structures between the different countries of the host cockroaches. Here we investigated the P. fuliginosa invasive to Japan and found that 100% of individuals were infected with one nematode species. According to the morphology and the sequence of the D2/D3 expansion segment of the 28S ribosomal RNA gene, we identified the parasite as Leidynema appendiculata. This nematode reproduced by haplodiploidy and its developmental timing under various conditions is quite divergent. Their population in the hindgut of P. fuliginosa was controlled with a few adult females and a male. ...
