{"title":"A new cryptic species of Australian Glyptotermes (Isoptera: Kalotermitidae) discovered by effective use of morphological characteristics of primary reproductives","authors":"Toshihisa Yashiro,&nbsp;Nathan Lo","doi":"10.1111/aen.12677","DOIUrl":"https://doi.org/10.1111/aen.12677","url":null,"abstract":"<p>Closely related species within termite genera often show extremely similar morphology, where morphological characteristics of soldiers alone or imagos (including alates and primary reproductives) alone are sometimes insufficient to establish new species. 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. It therefore forms a species complex with <i>G. iridipennis</i>. Although we could collect alates of <i>G. matsuurai</i> from only one of the field-collected colonies kept in the laboratory, we conducted morphological analyses of imagos from multiple colonies by using primary reproductives collected from field colonies. As a result of our morphological analyses of imagos, we found that <i>G. matsuurai</i> is morphologically distinguishable from all other species of Australian <i>Glyptotermes</i>. Thus, when enough alates are unavailable, morphological characteristics of primary reproductives can be used to facilitate the discovery of undescribed cryptic species at least in the genus <i>Glyptotermes</i> and possibly in other genera within the family Kalotermitidae.</p>","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"63 1","pages":"4-11"},"PeriodicalIF":1.6,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140135457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In most cases, crop aphids are controlled with broad-spectrum insecticides; although generally very effective at preventing yield loss, this approach risks non-target damage to beneficial organisms. In the last 20 years, a number of selective insecticides have become available to control aphids while minimising harm to other arthropods. Previous studies have found that two such insecticides, flonicamid and afidopyropen, cause only low-level acute mortality impacts on aphid parasitoids in Australian grain crops. However, little research has examined the sub-lethal effects of these chemicals, which could induce various physiological changes that impact pest control. We hypothesised that both flonicamid and afidopyropen have negative effects that extend beyond the immediate acute mortality previously published. To test this hypothesis, we undertook a series of experiments to determine the effects of flonicamid and afidopyropen, along with the synthetic pyrethroid gamma-cyhalothrin, on aphid parasitism (mummification) rate, emergence rate of the next generation and the next generation sex ratio in three important aphid parasitoids, <i>Aphidius colemani</i> (Viereck), <i>Diaeretiella rapae</i> (M'Intosh) and <i>Aphelinus abdominalis</i> (Dalman). Analogous with previous research, our acute toxicity bioassays showed that all three insecticides had low (&lt;30%) mortality impacts. Although sub-lethal impacts could not be assessed for <i>D. rapae</i> due to the low level of aphid parasitism by that species, our findings showed negative impacts on fecundity in surviving <i>A. abdominalis</i> and <i>A. colemani</i>. Of particular note is the increase in International Organisation for Biological Control ratings to moderate (30%–80% mortality and/or reproductive reduction) when mortality and reduced fecundity effects were combined to determine overall fitness impacts. Gamma-cyhalothrin typically resulted in higher negative impacts on <i>A</i>. <i>abdominalis</i> and <i>A</i>. <i>colemani</i> (compared with flonicamid and afidopyropen); however, quite surprisingly, these impacts were not rated as highly toxic. Taken together, our results suggest that, even when sub-lethal impacts are considered, flonicamid and afidopyropen are useful tools for farmers targeting aphid populations while minimising the non-target impacts on parasitoids. We recommend semi-field and/or field trials to further assess the impacts of these insecticides on aphid parasitoid populations.</p>","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"63 1","pages":"120-130"},"PeriodicalIF":1.6,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aen.12679","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139598527","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}

A series of three laboratory-based studies reared newly hatched larvae of <i>C. vicina</i> on meatmeal with varying amounts of either whole egg powder, whole eggs (including shells), bran flakes, brewer's yeast, fish paste or milk powder. The objective was to determine the best larval media for quick and efficient production of adult flies in a mass-rearing environment. Pure meatmeal or meatmeal with only brewer's yeast added were the least productive media. Larvae fed meatmeal with either 10% or 20% whole dried egg powder had the fastest development to pupae, the highest pupation rate, the heaviest pupae and the highest subsequent adult eclosion. Larval media containing fish paste had the highest survival through to adult emergence (&gt;85%) of all the media treatments, which suggests that this ingredient is of value when mass rearing <i>C. vicina</i>. In addition, newly hatched larvae (<i>n</i> = 50) were reared on varying amounts of media (i.e., 4, 2, 1, 0.5, 0.25 and 0.125 g per larvae) to determine the minimum amount of media required to produce adults. Reductions in media per larvae resulted in smaller pupae and adults that emerged with no subsequent reduction in adult eclosion, indicating the adaptability of this fly to food deprivation. Replacing whole egg powder with whole eggs reduces the costs of rearing <i>C. vicina</i> larvae significantly. In order to rear 1 million adult <i>C. vicina</i>, these studies showed that 0.5 g of media per larvae is sufficient to produce high numbers of pupae with &gt;95% adult eclosion. Although larval development and pupation are optimal on media containing whole egg powder, its recent rapid rise in costs makes it far less economical compared with the use of discarded whole eggs from egg producers. Sourcing of seafood waste could also reduce media costs and improve production of <i>C. vicina</i>. The costs of each media required to realise 1 million adult <i>C. vicina</i> are between $540 and $1900 depending on the media ingredients.</p>","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"63 1","pages":"96-109"},"PeriodicalIF":1.6,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139600871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
