Parasitoid Development

We evaluated possible improvements to the mass rearing of the larval parasitoid Habrobracon hebetor (Say) (Hymenoptera: Braconidae) on irradiated host wax moth Galleria mellonella L. and Indian meal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) larvae. The use of irradiated G. mellonella and P. interpunctella larvae at the dose of 150 Gy proved useful for enhancing the parasitism and adult emergence of H. hebetor due to the absence of negative repercussions on parasitoid development. Overall, parasitism was increased as the host larvae was irradiated with higher doses, while significantly higher parasitism was recorded at 150 and 300 Gy compared to lower doses. The female parasitoids preferred the irradiated larvae and significantly higher numbers of larvae were parasitized compared with non-irradiated larvae. The results also showed that irradiated larvae of G. mellonella served better as hosts for H. hebetor as compared with irradiated larvae of P. interpunctella. The implementation of these findings would be helpful for improving the mass production of parasitoids and the effectiveness of releases of biocontrol agents for the control of stored product pests.

Abstract The mating attributes in relating to parasitism and progeny production capacity of the parasitoid Habrobracon hebetor Say, using Plodia interpunctella (Hübner) as a host, were investigated in laboratory studies. The results indicated that 100% of the host larvae were parasitized by different individuals of H. hebetor females that were mated by the same male. Mating duration did not differ significantly among different successive matings with different females and had no effect on the rate of parasitism. In general, pairs that had their copulation early after emergence exhibited the maximum rate of parasitism as compared to delayed intervals. Moreover, the age of the H. hebetor females had no effect on the percentage of parasitism. The maximum parasitism percentage was recorded for the H. hebetor individuals that had been developed from the age group of the 6-d-old adults. The male: female ratios did not differ significantly among the female age groups. The percentage of parasitism clearly indicated a decrease with the increase of the male: female ratio. Overall, the results of the present work can be further utilized in mass rearing and release of H. hebetor in biological control programs in stored product protection.

Accumulated Degree Days

Immature development times of the Indian meal moth, Plodia interpunctella were studied in the laboratory at four different constant temperatures (20, 23, 25, 27°C) reared on a standard diet (D1) and chocolate (D2). The minimal duration of development from oviposition to adult emergence was inversely related to temperature, ranging from 2.3±0.36 days to 50.5±0.5 days for D1 and from 36.7±0.53 days to 106.73±1.10 days for D2 for 27°C and 20°C, respectively. The minimum development threshold (tL), obtained from linear regression model of the development rates at the four studied constant temperature regimes, for total immature development is 15.3°C and 17.1°C for D1 and D2, respectively and the accumulated degree days (ADD) for P. interpunctella is 249.51°C for D1 and 358.4°C for D2 above the threshold.

Abstract In Iran, the Indian meal moth, Plodia interpunctella (Hübner), is one of the most important pests of such stored products as date fruits and pistachio nuts. Ozone was applied as a gas at four concentrations (0, 2, 3, and 5 ppm) for four different periods (30, 60, 90, and 120 min) on the immature stages of P. interpunctella. The results indicated that by increasing the concentration and exposure time, the rate of mortality increased for all tested stages. This study showed that 12-day-old larvae were more susceptible than other stages when exposed to 5 ppm ozone for 120 min. The next in order of susceptibility were pupae, then 5-day-old larvae, and 17-dayold larvae had the highest sensitivity to ozonation. At the highest concentration of ozone, for the longest time, the least mortality rate was recorded for one-day-old eggs. According to the results, a reduction in the population density of P. interpunctella in laboratory experiments is promising. However, validation studies will be necessary to fully determine the potential of ozone as a replacement for the current post harvest chemical control of P. interpunctella on either pistachio nuts or date fruits.
