“…The data suggest that P. farinosus besides having a wide distribution, has its biology associated to Asteraceae, without host specificity -their adults were reared from plants of 56 different plant species belonging to eight tribes of Asteraceae (Silva & Mello 2008). As only flowerheads of Asteraceae were collected, is not possible to say that this lauxaniid species do not use flower resources from other plants for its larval development.…”

The genus Physoclypeus Hendel, 1907 has its distribution restricted to the Neotropical region. In this study, its species have been redescribed, three new combinations have been proposed, three lectotypes have been designated, seven new species have been described, and an identification key to the species is presented. An updated list of species of Physoclypeus is presented as: P. annulatus Hendel, 1925; P. coquilletti (Hendel, 1908); P. farinosus (Hendel, 1925); P. flavus (Wiedemann, 1830); P. hendeli sp. nov. (Type locality, Jamaica, N. Irish Town); P. lineatus (Williston, 1896) new comb.; P. montanus (Becker, 1919) new comb.; P. plaumanni sp. nov. (Type locality, Brazil, Santa Catarina); P. risaraldensis sp. nov. (Type locality, Colombia, Risaralda); P. saltensis sp. nov. (Type locality, Argentina, Salta); P. scutellatus (Curran, 1926) new comb.; P. unimaculatus sp. nov. (Type locality, Mexico, Vera Cruz); P. vitattus sp. nov. (Type locality, Brazil, Santa Catarina) and P. zebrinus sp. nov. (Type locality, Costa Rica, Limón).

“…All baited traps with live yeast cultures attracted flies of the families Lauxaniidae and Phoridae. Lauxaniid larvae are known to feed on microorganisms such as fungi, yeast, and bacteria (Silva and Mello, 2008). Larval feeding on fungi is also known for phorids, and adults are regarded as efficient vectors of diseases, especially in mushroom cultures.…”

Survey of arthropod assemblages responding to live yeasts in an organic apple orchard

Associations between yeasts and insect herbivores are widespread, and these inter-kingdom interactions play a crucial role in yeast and insect ecology and evolution. We report a survey of insect attraction to live yeast from a community ecology perspective. In the summer of 2013 we screened live yeast cultures of Metschnikowia pulcherrima, M. andauensis, M. hawaiiensis, M. lopburiensis, and Cryptococcus tephrensis in an organic apple orchard. More than 3000 arthropods from 3 classes, 15 orders, and 93 species were trapped; ca. 79% of the trapped specimens were dipterans, of which 43% were hoverflies (Syrphidae), followed by Sarcophagidae, Phoridae, Lauxaniidae, Cecidomyidae, Drosophilidae, and Chironomidae. Traps baited with M. pulcherrima, M. andauensis, and C. tephrensis captured typically 2.4 times more specimens than control traps; traps baited with M. pulcherrima, M. hawaiiensis, M. andauensis, M. lopburiensis, and C. tephrensis were more species-rich than unbaited control traps. We conclude that traps baited with live yeasts of the genera Metschnikowia and Cryprococcus are effective attractants and therefore of potential value for pest control. Yeast-based monitoring or attract-and-kill techniques could target pest insects or enhance the assemblage of beneficial insects. Manipulation of insect behavior through live yeast cultures should be further explored for the development of novel plant protection techniques.

“…The family Lauxaniidae is species-rich and globally distributed, with three subfamilies, more than 170 genera, and nearly 2100 described species [ 1 ]. Lauxaniids have a variety of habitats [ 2 , 3 ], mainly scavenging and fungus feeding [ 4 , 5 ], and have the habit of visiting flowers [ 6 , 7 ]. They play a very important role in the ecological system, degrading organic matter, plant pollination, and maintaining ecological balance [ 8 , 9 , 10 ].…”

The genus Homoneura comprises over 700 described species in eight known subgenera distributed worldwide and has the highest species richness of Lauxaniidae. Five subgenera and more than 200 species have currently been recorded from China. Despite its high diversity, the monophyly of Homoneura and its subgenera, and the phylogenetic relationships among its subgenera remain to be investigated. One maximum-parsimony tree was generated based on 105 morphological characters scored from 24 species, representing all five subgenera of Homoneura recorded from China. The results did not support the monophyly of the genus Homoneura and subgenus Homoneura. The subgenus Chaetohomoneura is a sister to subgenus Neohomoneura. The monophyly of the subgenera Euhomoneura and Neohomoneura is supported. Much of the current classification of the genus Homoneura needs a revision before taxonomy can reflect natural groupings.
