“…These features appear to be common in taxa that practice extraoral digestion (Samways et al 1997) which involves injecting their prey with hydrolytic enzymes and then sucking out the liquified body contents (Giorgi et al 2009). Larvae of Diomus terminatus and D. notescens Blackburn, 1889 have been observed to suck out the liquid contents of their aphid prey and discard the collapsed husk (Hopkinson et al 2016;Akbar et al 2009). We observed a similar process in Moiradiomus larvae, which feed on the liquid contents of food bodies and then use the collapsed food bodies to reinforce their tents.…”

A new genus of lady beetle, Moiradiomus gen. nov. (Coleoptera: Coccinellidae Latreille, 1807: Diomini Gordon, 1999 ), and four new species are described from Costa Rica, representing the first known occurrences of obligate phytophagous lady beetle species outside of the tribe Epilachnini Mulsant, 1846 (sens. Ślipiński 2007). The new species are described, illustrated and keyed, and their life histories discussed. Each species of Moiradiomus occurs on a separate species of Piper L., 1753 (Piperaceae Giseke, 1792), where the larva constructs a small silken tent between leaf veins and inside this shelter induces the production of food bodies, which are its exclusive source of food. Background information is provided on lady beetle trophic relations and other insect/Piper symbioses. The taxonomic history of Diomus Mulsant, 1850 and related species in the tribe Diomini is reviewed and existing errors in observation, interpretation, identification, and classification are corrected in order to provide a more meaningful context for understanding the new genus. The tribe Diomini is rediagnosed and recircumscribed to include Diomus, Decadiomus Chapin, 1933, Heterodiomus Brèthes, 1925, Dichaina Weise, 1923, Andrzej Ślipiński, 2007, and Moiradiomus. Magnodiomus Gordon, 1999 and Erratodiomus Gordon, 1999 are removed from Diomini and transferred to Hyperaspidini Costa, 1849, subtribe Selvadiina Gordon, 1985 stat. nov. Mimoscymnus Gordon, 1994 and Planorbata Gordon, 1994, originally described in Coccidulini Mulsant, 1846 are also transfered to Hyperaspidini and placed in Mimoscymnina subtribe nov. (type genus Mimoscymnus). The main morphological characters distinguishing Diomini and Hyperaspidini are described and illustrated. A key to genera of Diomini sensu novo is provided. The identification of the Australian Diomus species illustrated in Gordon’s publication on North American lady beetles is corrected from D. pumilio Weise, 1885 to D. tenebricosus (Boheman, 1859), however specimens recently collected in California do not match these genitalic illustrations and are identified as true D. pumilio. The following species of Diomus are transferred to Decadiomus as new combinations: D. balteatus (LeConte, 1878), D. floridanus (Mulsant, 1850), D. amabilis (LeConte, 1852), D. liebecki (Horn, 1895), D. myrmidon (Mulsant, 1850), D. humilis (Gordon, 1976), D. pseudotaedatus (Gordon, 1976), D. taedatus (Fall, 1901), D. bigemmeus (Horn, 1895), and D. austrinus (Gordon, 1976). Decadiomus seini Segarra, 2014 is placed as a junior synonym of D. austrinus. The following new species of Moiradiomus are described: M. clotho sp. nov., M. lachesis sp. nov., M. atopos sp. nov., M. nanita sp. nov.

“…Its natural enemies are larvae and adults of ladybirds (Coccinellidae) such as Menochilus sexmaculatus and Coccinella transversalis (Agarwala and Ghosh 1988). The ladybird Diomus notescens (Blackburn, 1888) is known to prey on Aphis gossypii (Hopkinson et al 2016) and also by Micraspis frenata (Erichson, 1842) and Coelophora inaequalis (Fabricius, 1775), all three being present in New Caledonia (Nattier et al 2015). It can be also controlled by hoverfly larvae (Syrphidae) and Aphidiinae wasps (Braconidae), especially Aphidius colemani.…”

Thirty-three species of aphids are now established in New Caledonia. All species appear to have been introduced accidentally by human activity in the last century. Here, 17 aphid species are recorded for the first time: Aphis eugeniae, Aphis glycines, Aphis odinae, Aulacorthum solani, Brachycaudus helichrysi, Cerataphis orchidearum, Greenidea psidii, Hyperomyzus carduellinus, Hysteroneura setariae, Lipaphis pseudobrassicae, Micromyzus katoi, Myzus ornatus, Pentalonia caladii, Rhopalosiphum nymphaeae, Rhopalosiphum rufiabdominale, Schizaphis rotundiventris, and Tetraneura fusiformis. Thirteen more species are also more or less regularly intercepted at the borders through biosecurity surveys, without further establishment. This demonstrates that aphids represent a major biosecurity threat, including a threat as potential plant virus vectors. The reinforcement of biosecurity is a priority for such biodiversity hotspots, from the perspectives of both agriculture and the native environment. Prioritisation and promotion of local development of vegetable and fruit production, rather than their risky importation from abroad, is desirable. Such an approach also should be promoted and extended to other Pacific islands, which all share the lack of native aphid fauna and their associated plant disease vector risks.

Performance of the Natural Mortality Factors of Aphis gossypii (Hemiptera: Aphididae) as a Function of Cotton Plant Variety and Phenology

Natural mortality factors are responsible for regulating pest populations in the field. However, plant attributes such as the variety and phenological stage can influence the performance of these factors. Therefore, we investigated the performance of the natural mortality factors of Aphis gossypii (Glover; Hemiptera: Aphididae) as a function of the plant variety and phenology. To investigate the performance of these factors, we evaluated the mortality of A. gossypii caused by natural mortality factors for 2 yr in field conditions in transgenic (Bacillus thuringiensis/Roundup Ready) and non-transgenic cotton crops during vegetative, flowering, and fruiting stages. The natural mortality factors were affected similarly between the transgenic and non-transgenic plants; however, differences were observed in their performance, depending on the phenological stage of the cotton plant. Compared with other stages, predation was higher in the flowering stage, whereas the mortality caused by rainfall was higher in the vegetative stage. Coccinellid beetles were primarily responsible for the predation on A. gossypii. These findings highlight that the performance of the natural mortality factors of A. gossypii varied more as a function of the phenological stage of cotton than of the variety.
