| الوصف: | Pineapple mealybug, Dysmicoccus brevipes (Hemiptera: Pseudococcidae), is a significant pest in pineapple production and a key trade barrier. We explored the potential use of ethyl formate (EF) as a methyl bromide alternative for the postharvest fumigation of D. brevipes in imported pineapples. When treated at 8 °C for 4 h, EF fumigation was effective against D. brevipes with LCt 99, the lethal concentration × time product of EF necessary to achieve 99% mortality of D. brevipes nymphs and adults at 64.2 and 134.8 g h/m 3 , respectively. Sorption trials conducted with 70 g/m 3 EF for 4 h at 8 °C using 7.5, 15 and 30% pineapple loading ratios ( w / v ) indicated that loading ratio lower than 30% is necessary to achieve the LCt 99 values required to control D. brevipes . In a scaled up trial using 1 m 3 chamber, EF fumigation with 70 g/m 3 for 4 h at 8 °C with 20% pineapple loading ratio ( w / v ) resulted in a complete control of D. brevipes treated. There were no significant differences in hue values, sugar contents, firmness, and weight loss between EF-treated and untreated pineapples. Our results suggest that EF is a promising alternative to methyl bromide fumigation for the postharvest phytosanitary disinfection of D. brevipes in pineapples. |
