“…However, our results are contradictory for some stages, such as the egg stage and 3 day‐old pupae, in which we did not find any statistical difference in lethal time between the two CO 2 concentrations. This is also in accordance with the literature, in which, in some situations, the time‐mortality response in different gas concentrations can be the same or nearly the same for some stages or some exposure periods …”

“…Briefly, test stages confined in small PVC vials were exposed to 90% and 96% CO 2 in 550 mL gas‐washing bottles with inlet and outlet valves, each containing 50 mL KOH solution to maintain humidity at a level of 65 ± 3%. The humidity level preferred is the optimum for the development of C. cautella and is in the range between 60%–70% RH that previously used by many authors . Larvae were offered approximately 1 g of the food that was used for insect rearing to prevent starvation and / or cannibalism, whereas other stages were not provided any food.…”

“…Many factors contribute to the efficacy of MAs against C. cautella . As a general rule, an increase in CO 2 or a decrease in O 2 , reduces the time for death to occur . Oxygen levels of 3% or below are considered to be a critical threshold for the initiation of anaerobic respiration, a decreased rate of ATP production, and a reduced rate of respiration .…”

“…This study was undertaken to obtain detailed information for the control of different age groups of all immature stages (three different ages for the eggs and pupae, and two different ages for larvae) and adults of C. cautella . Experiments were conducted at 65% RH, which is the optimum level for the development of C. cautella , previously used by many authors . From the point of view of practice, this study was planned to obtain complete mortality in the shortest time possible.…”

BACKGROUND Cadra (=Ephestia) cautella (Walker) is a serious cosmopolitan pest that can feed on a wide variety of stored foods. It is controlled mainly by fumigation with phosphine, to which strong resistance has been documented in major stored‐product insects in many countries. The need for reliable, user‐ and environmentally friendly alternatives is therefore high on the agenda to avoid the development of potential resistance and to reduce human exposure to toxic insecticides. Two modified atmospheres (MAs) composed of high carbon dioxide (CO2) and low oxygen (O2) (90% and 96% CO2 in air) were studied at the laboratory at 20 °C and 65 ± 3% relative humidity (RH) against C. cautella. RESULTS Eggs (1, 2, and 3 days old), young and mature larvae (10 and 20 days old), pupae (1, 2 and 3 days old) and adults (1 day old) were exposed to two MAs consisting of high CO2 and low O2 for the range of 2 to 104 h. Eggs, old larvae, and pupae were found to be the most tolerant. Adults were rather easily killed and young larvae were the most susceptible. Lethal exposure time (LT99) values were between 11.74 h and 128.97 h. CONCLUSION Modified atmospheres consisting of high CO2 and low O2 offer an affordable combination to control C. cautella effectively. From the perspective of economics and efficacy, 90% CO2 might be the concentration of choice. © 2019 Society of Chemical Industry

BACKGROUND: (Z,E)-9,12-tetradecadienyl acetate (ZETA, Z9,E12-14:OAc) is a major sex pheromone component for many stored-product moth species. This pheromone is used worldwide for mating disruption, detection, monitoring, and mass trapping in raw and processed food storage facilities. In this study, we demonstrate the biological production of ZETA pheromone by engineered yeast Saccharomyces cerevisiae. RESULTS:We mined the pheromone gland transcriptome data of the almond moth, Ephestia (Cadra) cautella (Walker), to trace a novel E12 fatty acyl desaturase and expressed candidates heterologously in yeast and Sf9 systems. Furthermore, we demonstrated a tailor-made ZETA pheromone bioproduction in yeast through metabolic engineering using this E12 desaturase, in combination with three genes from various sources coding for a Z9 desaturase, a fatty acyl reductase, and an acetyltransferase, respectively. Electrophysiological assays (gas chromatography coupled to an electroantennographic detector) proved that the transgenic yeast-produced ZETA pheromone component elicits distinct antennal responses.CONCLUSION: The reconstructed biosynthetic pathway in yeast efficiently produces ZETA pheromone, leaves an undetectable level of biosynthetic intermediates, and paves the way for the economically competitive high-demand ZETA pheromone's bioproduction technology for high-value storage pest control.

Methyl bromide is an excellent fumigant but has been banned because it has high potential for depleting the ozone layer which leads to many environmental and human health hazard issues. In this connection, effectiveness of carbon dioxide (CO, 99.9%) was studied as an alternative to methyl bromide under various exposure timings, 25 ± 1 °C, against different developmental stages of the almond moth, Cadra cautella, and red flour beetle, Tribolium castaneum. In case of C. cautella, the LT against adult, pupa, and larval stages was achieved after 37.5, 78.1, and 99.9 h of CO application, respectively. While for T. castaneum, the LT values were obtained after exposure timings of 29.3, 153.9, and 78.4 h against adult, pupa, and larval stages, respectively. Adults were very susceptible; in contrast, pupae and larvae were more tolerant. The susceptibility order was observed as follows: T. castaneum adult > C. cautella adult > C. cautella pupae > T. castaneum larvae > C. cautella larvae > T. castaneum pupae. This study could be useful in developing the management strategies to prevent stored dates from C. cautella and T. castaneum infestation.
