Field suppression of the peachtree borer, Synanthedon exitiosa, using Steinernema carpocapsae: Effects of irrigation, a sprayable gel and application method

Entomopathogenic Nematode Application Technology

“…In contrast to the above, certain studies did not detect EPN efficacy differences when comparing application equipment, e.g., when targeting codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), using a lance applicator versus an airblast sprayer (Lacey, Arthurs, Unruh, Headrick, & Fritts, 2006) or targeting the peachtree borer, Synanthedon exitiosa (Say) (Lepidoptera: Sesiidae) using a trunk sprayer, handgun or boom sprayer (Shapiro-Ilan, Cottrell, Mizell, Horton, & Zaid, 2015). The trunk sprayer is an attractive approach because the equipment uses smart technology to only spray when passing a trunk, thereby reducing waste of nematodes (or other product) between trees ( Fig.…”

“…Applications of S. carpocapsae for control of S. pictipes, were greatly enhanced by a follow-up application of a sprayable gel (the gel is commonly used for protecting structures from fire) (Shapiro-Ilan et al). Recently, the gel was also shown to be useful when tank-mixed directly with the nematodes at a lower concentration (<2 % prevents nozzle clogging) and the gel can also be applied to the soil surface during ground applications to protect EPNs from UV radiation and desiccation (in lieu of irrigation) (Shapiro-Ilan et al, 2015) (Fig. 9.2).…”

Formulation of entomopathogenic nematodes for crop pest control - a review

“…However, there are many factors that affect their survival time: sedimentation, high oxygen demand, decreased response of some species at low temperatures, susceptibility to microbial contamination, special storage conditions and appropriate concentration for each species (Grewal & Peters 2005). Also, the refrigeration requirements increase costs, hinder the transport (Grewal 2002) and involve the use of application equipment with specific requirements (Toepfer et al 2010;Brusselman et al 2012;Lacey & Georgis 2012;Beck et al 2014;Shapiro-Ilan et al 2015).…”
