The rice leaf folder, Cnaphalocrocis medinalis, showed a circadian rhythm in its calling behavior at 25 ± 1 o C. Female moths showed calling behavior most frequently 5-7 h into the scotophase under LD 15:9. Female moths at age 4 (days), after entraining at LD 15:9, showed a free-running rhythm for at least two more cycles in continuous darkness. The rhythm was damped out in constant light. The temporal pattern in the calling behavior was affected by different LD cycles (LD 15:9, 12:12, and 9:15), indicating that the rhythm in calling behavior was entrained by the LD cycles. By changing one photoregime condition to another after calling had been initiated, it was shown that C. medinalis females use the light-off signal to phase-set the circadian rhythm of calling behavior. Our results suggest that the rhythm in calling behavior is a circadian rhythm entrained by LD cycles.

“…An endogenous calling rhythm for females placed in continual scotophase has been demonstrated in two moths: Trichoplusia ni (Hiibner) by Sower et al (1970) and Anagasta kiihniella (Zeller) by Traynier (1970). It is known in two saturniid species that the corpora cardiaca is a prerequisite for calling behaviour (Riddiford and Williams 1971).…”

Can. Ent. 105: 1505Ent. 105: -1512Ent. 105: (1973 In Holomelina immaculata (Reakirt) periodicity of male attraction to synthetic 2-methylheptadecane, the female-produced sex pheromone, is modified by temperature cues. In the field this response interval occurs from approximately sunset to about 4 h after sunset on a warm day and night (30" to 17°C) and for the 2 h prior to sunset on a cool day and night (23" to 16°C).In laboratory studies at 24°C female H. irnmaculata placed in continual scotophase have an endogenous calling rhythm, but they are apparently inhibited from calling by constant photophase. In 16:s or 12:12 light-dark cycles at 24°C calling occurs from the 2nd to the 6th hour of scotophase, whereas at 15°C calling takes place from the initiation to the 5th hour of scotophase. The critical cues governing initiation of calling behaviour are lights-off or a temperature decrease cue, and a temperature decrease signal overrides the apparent inhibitory effect of continual photophase.

“…2014), and in recent decades, increasing light pollution (Hölker et al 2010). Artificial lights inhibit the release of pheromones in female moths and effect ovipositioning (Nemec 1969, Sower et al 1970. If a moth oviposits an unusually high density of eggs in a small space in an unsuitable location near light, the result is an ecological trap (Pfrimmer et al 1955, Brown 1984) that increases competition for limited food sources among caterpillars (MacGregor et al 2015).…”

-We examined the light sources and illuminated environments in Sopron's public areas and studied the impact they had on the composition of macrolepidopteran moth communities. We employed light traps with three different light sources in three differently illuminated environments (seminatural, transitional, urban) on 60 occasions during the summer period of 2012-2013 and 20 times in the seminatural area in the spring and autumn of 2014. In the first two years, we evaluated the number of individuals; in year three, we evaluated the number of species. In the first two years, the high-pressure sodium light in the seminatural site trapped the largest number of nocturnal lepidopteran specimens (2,569), while the mixed HMLI light trapped the most individuals in the transitional (1,098) and urban (822) areas. Based on the average number of individuals the first two years, we compared the locations and light sources. In terms of average number of specimens collected, significant differences emerged between two light sources and two locations. When we completed the species diversity index, we determined the compact fluorescent tube in spring and the high-pressure sodium light in the autumn showed the greatest values.light pollution / Lepidoptera / light trapping / Sopron / illumination Kivonat -A mesterséges fényforrások hatása az éjszakai nagylepke közösségek (Lepidoptera Macroheterocera) összetételére. Sopron város közterületein előforduló fényforrások és az ebből eredő eltérő megvilágítottságú környezet hatását vizsgáltuk az éjszakai nagylepke közösségek összetételére. Három különböző típusú fényforrással ellátott fénycsapdát használtunk három eltérő megvilágítottságú környezetben (természetközeli, átmeneti, városi). 2012-2013 év nyarán 60, 2014 tavaszán és őszén a természetközeli helyszínen 20 alkalommal gyűjtöttünk mintákat. Az első két évben egyedszám, a harmadik évben fajszám szerint végeztük a kiértékelést. Az éjszakai nagylepkék egyedszáma az első két évben a természetközeli területen volt a legmagasabb; a nagynyomású nátrium lámpánál (2,569), az átmeneti (1,098) és a városi területen (822) a HMLI kevert lámpa esetén. A fényforrások összehasonlításánál két helyszínen, a területek összehasonlításánál két fényforrás típusnál volt szignifikáns eltérés az egyedszámok átlaga között. A diverzitás vizsgálatnál a diverzitási mutatók tavasszal a kompakt fénycsőnél, ősszel a nátrium lámpánál mutattak nagyobb diverzitási értéket.fényszennyezés / Lepidoptera / fénycsapázás / Sopron / megvilágítottság
