There are also other botanical essential oils with control potential, such as garlic oil (A. sativum) which possessed contact toxicity (LD50 = 1.42 µg/adult) to overwintering adults of C. chinensis (Zhao et al. 2013) and AkseBio2 (a natural botanical essential oil mixture of thyme, oregano, anise, sesame oil, and maize oil plus a natural emulgator and a fluorescent bacterium, Pseudomonas fluorescens, TR 97) which showed strong activity against the nymphs of pear psylla, Cacopsylla pyri, with 87.40% mortality of younger nymph (first and second instars) and 62.10% mortality of the older (third-fifth instars) during 7 d at a concentration of 0.10% in laboratory (Erler 2004).
