“…The insects were shipped from YARL to Washington State University (WSU) (Pullman, WA) by overnight delivery for RF and hot water treatments. Since the fifth-instars were the most heat tolerant stage of the codling moth (Yokoyama et al, 1991;Wang et al, 2002aWang et al, , 2004, late fourth to early fifth-instars were removed from the artificial diet and used for artificial infestation of apples. Seven apples and 35 larvae per replicate were enclosed in a single ventilated plastic container.…”

Apples destined for export to Japan and South Korea are currently disinfested for codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), using methyl bromide fumigation. Restrictions and limitations imposed on the uses of methyl bromide have increased interest in developing alternative non-chemical quarantine treatments. It is imperative that the treatment is effective against codling moth yet maintains the quality of treated apples. The present study explored the application of radio frequency (RF) energy in conjunction with conventional hot water treatment to develop feasible heat treatments. Treatment parameters were selected based on minimum time-temperature conditions required for 100% mortality of fifth-instar codling moth and apple quality. The treatments included preheating of infested or wholesome apples in warm water at 45• C for 30 min. The preheated apples were then heated to 48• C in a hydraulic fruit mover placed between two parallel plate electrodes in a 12 kW, 27.12 MHz pilot scale RF system. RF treated apples were transferred to a 48• C hot water bath and held for 5, 10, 15 and 20 min before being hydro-cooled in ice water for 30 min. The mortality of codling moths in the infested apples was assessed, and the quality of wholesome apples was evaluated by measuring weight loss, firmness, color, soluble solids content, and titratable acidity after 0, 7, and 30 days of storage at 4• C. The results showed that the treatment at 48• C for 15 min was the most practical and effective both for insect control and apple quality.

“…Cold storage and controlled atmospheres also require lengthy treatment times for disinfestation, and there is concern over public acceptance of irradiated food. Heat treatments have been proposed to kill codling moth in different commodities using forced hot air or hot water dips (Yokoyama et al, 1991;Jones and Waddell, 1997), but the lengthy exposure times needed may cause injury to the product (Lurie, 1998). Industrial radio frequency and microwave systems, extensively used in the food processing, textile and wood processing industries, may provide more rapid product heating (10-201C min…”

“…These methods include directly exposing insects in a water bath for specific times, heating insects in tubes which in turn are submerged in a water bath, or heating insects in fruits (Yokoyama et al, 1991;Thomas and Mangan, 1997;Waddell et al, 2000). A heating block system was developed at Washington State University (WSU), Pullman WA, to study thermal-death kinetics of codling moth .…”

Information on kinetics for thermal mortality of navel orangeworm, Amyelois transitella (Walker) (Lepidoptera: Pyralidae), is needed for developing post-harvest phytosanitation thermal treatments of walnuts. Thermal-death kinetics for fifth-instar navel orangeworms were determined at temperatures between 461C and 541C at a heating rate of 181C min À1 using a heating block system. Thermal-death curves for fifth-instar navel orangeworms followed a 0.5th-order of kinetic reaction. The time required to achieve 100% mortality (N 0 ¼ 600) decreased with increasing temperature in a logarithmic manner. Complete kill of 600 insects required a minimum exposure time of 140, 50, 15, 6, and 1 min at 461C, 481C, 501C, 521C, and 541C, respectively. The reaction rate (k) was affected by treatment temperatures following an Arrhenius relationship. The activation energy for thermal kill of fifth-instar navel orangeworms was estimated to be between 510 and 520 kJ mol À1 . r

“…The reliable and repeatable results obtained from the HBS demonstrate that the latest instars were the most heat-tolerant life stage of the targeted insects. Yokoyama et al (1991) also observed that the fifth instar was the most heat-resistant life stage at 49-51 C using water heating. Thus, we selected fifth-instar C. cephalonica for this initial study.…”

“…Experimental methods for characterizing the temperature-time effect on insect mortality include directly exposing insects in a water bath, heating insects in tubes which in turn are submerged in a water bath, or heating insects in fruits (Yokoyama et al 1991, Thomas and Mangan 1997, Hansen and Sharp 2000, Waddell et al 2000. To provide more accurate and uniform temperature control for experiments, a heating block system (HBS) has been developed to study the thermal death kinetics of several important insect pests (Wang et al 2002a,b;Johnson et al 2003Johnson et al , 2004Gazit et al 2004;Hallman et al 2005).…”
