Development of Immature Stages of <I>Sesamia nonagrioides</I> (Lepidoptera : Noctuidae) Under Alternating and Constant Temperatures

Temperature-dependent development of Lista haraldusalis (Walker) (Lepidoptera: Pyralidae) on Platycarya strobilacea

“…Temperature significantly affected the required developmental time and the survival of all immature stages, as found in other insects (Fantinou et al, 2003;Sandhu et al, 2010;Shang et al, 2012Shang et al, , 2013, and it accelerated development to a maximum rate at 31°C for each immature stage and the overall immature stages, after which the developmental rate decelerated and ceased at 37°C.…”

Thermoperiodic effects on larval growth parameters of the Sesamia nonagrioides (Lepidoptera: Noctuidae)

“…Thus, under long daylength larval growth was faster while HCW and body weight were lesser comparing with that under a short one. Moreover, it has been recently proved that thermoperiod could reduce the thermal constant requirements of the various stages of this insect (Fantinou et al 2003). The present paper presents further experimental data on the thermoperiodic effects on the growth characteristics of larvae of this species.…”

“…Therefore, the effects of high temperatures (>35°C) during the day on larval development are less pronounced, because they alternate with lower temperatures during the night. On the other hand, Lopez et al (2001) and Fantinou et al (2003) estimated the upper threshold of larval development to be higher than 40°C.…”

“…Thus, each regime had a mean temperature corresponding to that of the constant selected, and the high temperature was synchronized with the photophase. Since our purpose was the comparison of larval development under constant and alternating temperatures, temperatures lower than 20°C or higher than 35°C were not tested, because the cryophase or the thermophase would be close to the lethal values (Fantinou et al 2003).…”

“…In temperate climates, insects are exposed to the fluctuation of the daily temperatures. Thermoperiod has been reported to influence development and growth of insects and a lot of studies have been published recently with contradictory results (Beck 1982(Beck , 1983(Beck , 1986Liu et al 1995;Fantinou et al 2003) In the Mediterranean Basin, Sesamia nonagrioides is one of the most important pests of corn, causing severe damages (Baniabassi 1981;Tsitsipis 1990). This insect is multivoltine with three to four generations and larvae over winter from the end of August till the end of January whereas it remains to a postdiapause condition afterward (Fantinou et al 1995(Fantinou et al , 1998 with the adults appearing first at the beginning of April in Greece (Tsitsipis 1990).…”
