Potential of Contact Insecticides to Control <I>Xyleborus glabratus</I> (Coleoptera: Curculionidae), a Vector of Laurel Wilt Disease in Avocados

“…Bolts were infested with 30 adult male and female X. glabratus taken from a colony reared at the UF Entomology and Nematology Department (Gainesville, Florida, USA), then held in the laboratory at 25 ± 2 °C under complete darkness for 4 wk (Brar et al 2013). The infested X. glabratus bolts were hung approx.…”

“…(Brar et al 2013); therefore, exposed bolts were considered to host cohorts of different ages and possibly the parent adults. Insects collected from the bolts were sent to the taxonomic identification resources mentioned above for identification.…”

“…Research to control the spread of the beetle has focused on the beetle's biology (Brar et al 2012), seasonality (Brar et al 2013), host preferences (Kendra et al 2014a), development of attractants (Kendra et al 2012b(Kendra et al , 2014bKuhns et al 2014a,b), repellents (Peña et al 2011), and chemical control of the vector (Peña et al 2011;Carrillo et al 2013), but little effort has been directed toward determining the presence or absence of natural enemies of X. glabratus. Studies on natural enemies of Scolytinae have provided mixed results.…”

Laurel Wilt in Natural and Agricultural Ecosystems: Understanding the Drivers and Scales of Complex Pathosystems

“…Prior to the laurel wilt epidemic, swamp bay occurred throughout the ENP. Swamp bay is highly susceptible to laurel wilt [26] and is attractive to, and supports significant egg production of, X. glabratus [158]. An aerial survey of the Everglades in 2011 and 2013 detected rapid spread of laurel wilt on this host tree [25].…”

Evaluation ofLitchi chinensisfor Host Status toXyleborus glabratus(Coleoptera: Curculionidae: Scolytinae) and Susceptibility to Laurel Wilt Disease

“…Two thin metal hoops were placed inside the sleeve and secured with binder clips, which prevented the sleeve from collapsing and further facilitated observations. Each sleeved trunk then received 10 female X. glabratus ( 3 d post-emergence), obtained from the University of Florida laboratory colony, which had been reared under conditions described by Brar et al (2013). The experiment was initiated in the early evening (18:00-18:30 h EDST), since this time period had been identified as the peak window during which female X. glabratus engage in host-seeking flight in Florida ( Bolts were checked at regular intervals and females were considered fully committed to boring (scored positive) when they were perpendicular to the substrate and half their body length (~1 mm) was inserted into the entrance hole (C, female on left).…”
