Susceptibility of the cigarette beetle Lasioderma serricorne (Coleoptera: Anobiidae) to hypoxia

Susceptibility of the cigarette beetle Lasioderma serricorne (Coleoptera: Anobiidae) to hypoxia The susceptibility of the cigarette beetle Lasioderma serricorne (F.) to hypoxia was examined at three different oxygen concentrations (0.5–0.8, 1.0–1.3, and 2.0–2.3 %) and four different temperature/humidity (RH) conditions: 30 °C/75 % RH, 25 °C/75 % RH, 20 °C/43 % RH, and 15 °C/43 % RH. The influence of humidity on mortality was also examined at three humidity levels (21, 43, and 75 % RH) at 1.0–1.3 % oxygen (O2) and 25 °C. Our results revealed that adult beetles were the most tolerant at 2.0–2.3 % O2 and that the larvae were the most tolerant at O2 levels <1.0–1.3 %. Mortality increased with increasing temperatures and decreasing O2 concentrations. At 30 °C, 75 % RH, and 0.5–0.8 % O2, the 99 % lethality (LT99) of larvae was 6.9 days; however, it increased to 20 days when the temperature was decreased to 25 °C or when O2 levels were increased to 1.0–1.3 %. Humidity also influenced mortality of both larval and adult beetles. LT99 values for larvae at 25 °C and 1.0–1.3 % O2 were 24.0, 44.6, and 50.2 days at 21, 43, and 75 % RH, respectively. Results of this study indicate that a controlled atmosphere (CA) with reduced oxygen levels (<0.5–0.8 % O2) represents an effective measure for disinfesting stored tobacco as an alternative to conventional phosphine fumigation at temperatures >30 °C. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Entomology and Zoology Springer Journals

Abstract

The susceptibility of the cigarette beetle Lasioderma serricorne (F.) to hypoxia was examined at three different oxygen concentrations (0.5–0.8, 1.0–1.3, and 2.0–2.3 %) and four different temperature/humidity (RH) conditions: 30 °C/75 % RH, 25 °C/75 % RH, 20 °C/43 % RH, and 15 °C/43 % RH. The influence of humidity on mortality was also examined at three humidity levels (21, 43, and 75 % RH) at 1.0–1.3 % oxygen (O2) and 25 °C. Our results revealed that adult beetles were the most tolerant at 2.0–2.3 % O2 and that the larvae were the most tolerant at O2 levels <1.0–1.3 %. Mortality increased with increasing temperatures and decreasing O2 concentrations. At 30 °C, 75 % RH, and 0.5–0.8 % O2, the 99 % lethality (LT99) of larvae was 6.9 days; however, it increased to 20 days when the temperature was decreased to 25 °C or when O2 levels were increased to 1.0–1.3 %. Humidity also influenced mortality of both larval and adult beetles. LT99 values for larvae at 25 °C and 1.0–1.3 % O2 were 24.0, 44.6, and 50.2 days at 21, 43, and 75 % RH, respectively. Results of this study indicate that a controlled atmosphere (CA) with reduced oxygen levels (<0.5–0.8 % O2) represents an effective measure for disinfesting stored tobacco as an alternative to conventional phosphine fumigation at temperatures >30 °C.
