Bradysia Odoriphaga Copulatory Behavior and Evidence of a Female Sex Pheromone

De novo sequencing and characterization of the Bradysia odoriphaga (Diptera: Sciaridae) larval transcriptome

“…Aggressive application of chemical insecticides (e.g., organophosphates, carbamates, neonicotinoids) is the most prevalent B. odoriphaga prevention method used on Chinese chive crops in China. This has led to an excessive use of insecticides, resulting in increased environmental pollution and high residues of insecticides in commercial chives crops Li et al, 2007).…”

“…The Chinese chive maggot, Bradysia odoriphaga Yang & Zhang (Diptera: Sciaridae), is the most harmful pest to the Chinese chive, Allium tuberosum Rottle ex Spreng (Liliaceae) crop (Li et al, 2007). Other plants, such as shallot (Allium ascalonicum), garlic (Allium sativum), cabbage (Brassica oleracea), radish (Raphanus sativus), celery (Apium graveolens), and mushrooms (Pleurotus ostreatus) are also negatively impacted by this pest (Mei et al, 2003).…”

Dissipation dynamics of clothianidin and its control efficacy against Bradysia odoriphaga Yang and Zhang in Chinese chive ecosystems

“…The Syracuse Environmental Research Associates (SERA) 35 reported that imidacloprid, applied at 0. 5 as tea and tomato, had different field half-lives in the soil of 7, 53 and 67-107 days. SERA had deemed clothianidin to be 'mobile to highly mobile', 31,36 and Wu et al 37 found that the soil organic content was the main factor affecting its adsorption and leaching in soils.…”

“…4,5 This insect feeds on the plants of seven families and more than 30 species, including the Chinese chive (Liliaceae), onion (Liliaceae), garlic (Liliaceae), Chinese cabbage (Brassica), cucumber (Cucurbitaceae), lettuce (Lactuca) and other vegetable crops, 5 -9 and causes production losses in mushroom sheds. 10 Its larvae feed on and live in the bulbs and pseudostems of Chinese chive, making it difficult to control using common strategies, although its other stages do not harm this plant.…”

Chromosomal localization and partial sequencing of the 18S and 28S ribosomal genes from Bradysia hygida (Diptera: Sciaridae)

“…In general, sciarid adults are simply considered to be a nuisance without causing major problems (Cloyd, 2000); however, the larvae of some species have been reported to cause major plant damage once they feed on their roots (Cloyd et al, 2007). Bradysia impatiens has been reported to be an economically problematic species in Florida (Mead, 1978), Bradysia species are known major insect pests in greenhouses (Meers and Cloyd, 2005), and Bradysia odoriphaga Yang and Zhang is the most serious pest of Chinese chive (Li et al, 2007). Bradysia hygida, first described by Sauaia and Alves (1968), is a sciarid that has been extensively used as a model system to study developmentally regulated gene transcription and amplification (Laicine et al 1984;Monesi et al 1995;Fiorini et al, 2001;Basso Jr et al, 2002;Candido-Silva and Monesi, 2010;Garcia et al, 2011;Passos et al, 2012).…”
