A Novel Composite as a Dispenser for Methyl Eugunol to Attract the Peach Fruit Fly, Bactrocera zonata (Saunders) Males under Field Conditions

Abstract

Peach fruit fly (PFF), Bactrocera zonata (Saunders) (Diptera: Tephritidae) is considered one of the most economic important insect pest for several kinds of fruit species. Present work seeks to explore for the preparation of a novel composite based on petroleum coke with polyethylene, oleic acid and natural rubber as a dispenser for methyl eugunol. This target aims to get efficient dispenser composite to attract PFF males under field conditions in comparison with standard liquid lure dispenser (cotton wick). In addition to favorably regulate the release rate of methyl eugenol (ME) to extend its effectiveness and stability for PFF attraction in comparison with standard lure dispenser (cotton wick) by using Jackson traps under field conditions. The obtained results showed that Composite prolonged the length of effective field ME duration to 18 weeks or longer; while, the length of effective field duration of cotton wick dispenser was 8 weeks only. The ability of cotton wick dispenser to attract PFF males was higher than that of Composite during the first six weeks (with no significant differences between the two dispensers in some of these weeks). On contrary, from the 7 th week till the end of the experiments, Composite dispenser showed significantly higher ability to attract PFF males. Efficacy from Composite dispenser did not significantly affected by the time passed after hanging traps; while, ME released from cotton wick dispenser decreased significantly by the time passed. On another hand, the efficacy of Composite dispenser did not significantly affected by air temperature degrees; while, the efficacy of cotton wick dispenser was significantly affected by air temperature degrees. Therefore, it could be concluded that the prepared composite may efficiently replace the cotton wick and could be applied at large scale in integrated pest management programs for PFF.

“…Also, they found that paraffin oil gave more stability than sunflower oil to methyl eugenol with passed time. According to (El-Adly, et al, 2018 andElmetwally 2017), the efficacy of a novel composite as a dispenser for methyl eugenol to attract the peach fruit fly did not significantly affected by the time passed after hanging traps; while, methyl eugenol released from cotton wick dispenser significantly decreased gradually by the time.…”

Influence of Methyl Eugenol Diluted with Oleic Acid as Lure for the Peach Fruit Fly (PFF) Males, Bactrocera zonata (Saunders) under Filed Conditions

“…According to (El-Adly, et al, 2018) that efficacy of a novel composite as a dispenser for methyl eugenol to attract the peach fruit fly did not significantly affected by the time passed after hanging traps; while, ME released from cotton wick dispenser decreased significantly by the time passed. The present study revealed that the most stable treatment all over ten weeks wasmethyl eugenol75% diluted with oleic acid; where, , at a concentration of 75% exhibited approximately similar potentiality towards B. zonata adult males with time.…”
