Effect of Monitoring Technique in Determining the Presence of Fungus Gnat, Bradysia spp. (Diptera: Sciaridae), Larvae in Growing Medium1
Monitoring tools for detecting the presence of fungus gnats (Bradysia spp.) are a critical part of effective IPM programs for these pests in greenhouse production systems. Research has demonstrated the effectiveness of yellow sticky cards for monitoring adult fungus gnats; similarly, potato disks placed on the surface of the growing media in pots have been shown to be effective monitoring tools...
متن کاملBiology and feeding requirements of larval hunter flies Coenosia attenuata (Diptera: Muscidae) reared on larvae of the fungus gnat Bradysia impatiens (Diptera: Sciaridae).
The larval feeding requirements and biology of the generalist predatory muscid hunter fly Coenosia attenuata Stein 1903 (Diptera: Muscidae) were investigated at 25 degrees C. Larval C. attenuata were fed second-, third, and fourth-instar (L2, L3, and L4) larvae of the fungus gnat Bradysia impatiens (Johannsen) (Diptera: Sciaridae) at variable rates to determine minimum and optimum numbers of th...
متن کاملObservations on Spermiogenesis in the Fungus Gnat Sciara Coprophila
Although 9-membered centrioles are found in somatic tissues of Sciara, the centriole which lies at the spindle pole of the second meiotic division in male Sciara is composed of a row of approximately 70 short tubules in an oval array. Shortly after telophase of this unequal division, in the daughter cell destined to undergo spermiogenesis, microtubules become confluent with the tubules of the c...
متن کاملBiological Activity of trans-2-Hexenal Against Bradysia odoriphaga (Diptera: Sciaridae) at Different Developmental Stages
trans-2-Hexenal, one of the C6 green leaf volatiles, is potentially useful for the control of Bradysia odoriphaga Yang et Zhang. In this study, the biological activity of trans-2-hexenal on B. odoriphaga was assessed in the laboratory. trans-2-Hexenal was observed to kill B. odoriphaga in different developmental stages at a relatively low concentration under fumigation. The respiration rate in ...
متن کاملEvaluation of Housekeeping Genes for Quantitative Real-Time PCR Analysis of Bradysia odoriphaga (Diptera: Sciaridae)
The soil insect Bradysia odoriphaga (Diptera: Sciaridae) causes substantial damage to Chinese chive. Suitable reference genes in B. odoriphaga (Bradysia odoriphaga) have yet to be identified for normalizing target gene expression among samples by quantitative real-time PCR (qRT-PCR). This study was focused on identifying the expression stability of 12 candidate housekeeping genes in B. odoripha...
