Paper wasp colonies at this site were surveyed and monitored weekly over two summers. Our data showed that only ~20% of the monitored colonies each year survived until late summer, with high rates of colony mortality in late spring and early summer. We collected samples of wasp larval guts over a temporal gradient in one nesting season, and via DNA metabarcoding analysis, we identified the prey species consumed. The prey species most frequently identified in larval samples were endemic cicadas and several lepidopteran species. No native arthropod species of known conservation concern were identified in the analysis. However, 63% of the unique taxon sequences retrieved could not be identified by genus or species level, likely due to the absence of reference barcodes. These taxa may represent a group of understudied species, potentially highly endemic or localised. Our analysis indicates that these invasive wasps are opportunistic-generalist predators with the potential to exert high predation pressure on native arthropods. <i>P. chinensis</i> may be preying on a range of understudied species, especially in remote, natural habitats across New Zealand.

While there is significant research on tephritid interspecific larval competition, it has been conducted in invasive situations where the species are evolutionarily novel to each other. There has been no published research investigating larval competitive interactions between naturally coexisting, endemic species. We ran laboratory-based, intraspecific and interspecific larval competition trials involving three co-occurring <i>Bactrocera</i> species of differing genetic relatedness and also measured aspects of juvenile development rate to test possible mechanisms of competitive difference. Larval density had an influence on intraspecific competition in <i>Bactrocera tryoni</i>, <i>Bactrocera neohumeralis</i> and <i>Bactrocera jarvisi</i>, with a decreasing percentage of pupation with increasing larval density. Interspecific competition between <i>B. tryoni</i> and <i>B. neohumeralis</i>, and between <i>B. tryoni</i> and <i>B. jarvisi</i> was influenced by the interaction between species and density. The intensity of competition between <i>B. tryoni</i> and <i>B. neohumeralis</i> was minimal but high between <i>B. tryoni</i> and <i>B. jarvisi</i>. <i>B. jarvisi</i> produced larger eggs and had faster initial larval growth rates than the other two species, but it took the longest time for pupation to occur.

Further, and contrary to other studies, egg size, hatch rate and larval growth rate did not provide <i>B. jarvisi</i> with a competitive advantage; thus, larval size does not appear to be a mechanism of larval competition between <i>B. tryoni</i> and <i>B. jarvisi</i>.</p>","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"63 2","pages":"270-282"},"PeriodicalIF":1.6,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aen.12686","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140754105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fire also causes indirect mortality to termites by removing food sources, which may give an advantage to larger mounds as they have superior food provisioning and storage ability. Using natural fires, we measured mound size and colony survival of two southern African termite species (<i>Trinervitermes trinervoides</i> and <i>Amitermes</i> sp.) in plots recently burnt (&lt;4 months after fire), recovering from fire (1–2 years after fire), or unburnt (&gt;3 years after fire). Burn status and mound size were each significant factors in colony survival. Recent fire was associated with the lowest survival, and larger mounds with greater survival.

However, many original descriptions of termite species are based on soldier characteristics alone, because of the seasonal occurrence of alates and the difficulty in collecting primary reproductives. Importantly, primary reproductives of the family Kalotermitidae (so-called drywood termites) are relatively easy to collect from field colonies compared with those of the other termite families. Here, we describe a new kalotermitid species, <i>Glyptotermes matsuurai</i> <b>sp. nov.</b>, from Australia by effective use of morphological characteristics of primary reproductives. <i>Glyptotermes matsuurai</i> is distinguished from the Australian species <i>G. iridipennis</i> Froggatt, 1896 by the mitochondrial cytochrome <i>c</i> oxidase subunit II gene; however, it is not distinguishable from <i>G. iridipennis</i> based on the external morphology of soldiers.
