Floral scents are among the key signals used by pollinators to navigate to specific flowers. Thus, evolutionary changes in scents should have strong impacts on plant diversification, although scent-mediated plant speciation through pollinator shifts has rarely been demonstrated, despite being likely. To examine whether and how scent-mediated plant speciation may have occurred, we investigated t...

Fungus gnats (Bradysia spp.) are major insect pests of greenhouse-grown horticultural crops mainly due to the direct feeding damage caused by the larvae, and the ability of larvae to transmit certain soil-borne plant pathogens. Currently, insecticides and biological control agents are being used successively to deal with fungus gnat populations in greenhouse production systems. However, these s...

Lygistorrhinidae is a small family of fungus gnats (Sciaroidea) that are rather homogenous and easily recognized by elongate mouthparts and reduced wing venation. Overall size is ca. 4 to 5 mm; mouthparts are greatly elongate, at least 3x as long as height of head, and consist of 5 filaments, a pair of one-segmented palpi, a pair of labellae, and a hypopharynx. Wings are ca. 2 mm long, with Sc ...

a survey was conducted to identify the fungus gnats (diptera: mycetophilidae) in kermanshah province (west of iran) during 2010-2011. the specimens were collected from nine different localities. adults were reared from the fruiting bodies of agaric fungi. five species are recorded for the first time from iran: mycetophila strigatoides (lundrock), allodia ornaticollis (meigen), rymosia pseudocre...

ABSTRACT A series of laboratory tests were conducted to investigate potential effects of fungus gnat (Bradysia impatiens) feeding damage on susceptibility of geranium seedlings (Pelargonium x hortorum) to infection by the root rot pathogen Pythium aphanidermatum. Effects were compared with those from similar tests in which the seedlings were mechanically wounded by severing the root tip with a ...

BACKGROUND AND AIMS Lepanthes is one of the largest angiosperm genera (>800 species). Their non-rewarding, tiny and colourful flowers are structurally complex. Their pollination mechanism has hitherto remained unknown, but has been subject of ample speculation; the function of the minuscule labellum appendix is especially puzzling. Here, the pollination of L. glicensteinii by sexually deceived ...

Five species of black fungus gnats are recorded from Ukraine for the first time: Bradysia forficulata (Bezzi, 1914), B. lobata Hondru, 1968, normalis Frey, 1948, urticae Mohrig & Menzel, 1992 and Lycoriella sativae (Johannsen, 1912). Distributions these summarized their diagnoses provided.

Five species of black fungus gnats Corynoptera furcifera Mohrig & Mamaev, 1987, Cratyna (Cratyna) fulvicauda (Felt, 1898), Lycoriella lundstromi (Frey, 1948), Pseudolycoriella paludum 1948) and Xylosciara (Xylosciara) heptacantha Tuomikoski, 1957 are recorded from Ukraine for the first time. Distributions these summarized diagnoses provided.

The black fungus gnats Bradysia similigibbosa sp. n. and B. irwini sp. n. are described and new records of species of Bradysia Winnertz, Ctenosciara Tuomikoski, Epidapus Haliday, Pseudolycoriella Menzel & Mohrig, and Scatopsciara Edwards are presented for New Caledonia. A checklist of the sciarids of New Caledonia is given.

Fungus gnats (Sciaridae) are one of the most devastating pests on mushroom farms. Generally, they controlled using relatively inefficient physical means, like sticky or pheromone traps, with chemical pesticides. Here, we have proposed an integrated fungus gnat control system combining a UV-A LED source at 365 nm and high-power laser diode 445 nm. The serves light trap, since previous studies co...
