“…However, it led to virtually complete loss of egg viability. As in the present results, exposure of adult insects to novaluron did not affect the number of eggs laid but reduced the number of viable eggs in red flour beetle ( Tribolium castaneum [Herbst])26 and whitefly ( Bemisia argentifolii Bellows & Perring) 27. Malinowski and Pawinska28 also reported that a large proportion of Colorado potato beetle eggs on small field plots treated with novaluron failed to hatch, but they did not provide any data to quantify the stated reduction in egg viability.…”

“…It has also been demonstrated that exposure to novaluron does not negatively impact the fecundity of female Leptinotarsa decemlineata (Alyokin et al 2008, 2009) or Tribolium castaneum (Kostyukovsky and Trostanetsky 2006). …”

The codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is a primary pest of apples throughout the United States. Reliance on broad spectrum organophosphates has been declining with the slated cancellation and has shifted towards narrow spectrum insecticides. Novaluron, a chitin synthesis inhibitor, has primarily been used for its ovicidal and larvacidal activities. However, recent studies have demonstrated a transovarial effect after exposure to adults. The effects of novaluron were studied to determine if reduced egg hatch occurs after exposure of different sexes to this compound. Effects of this compound through horizontal transfer were also compared with a topical application to C. pomonella eggs. Results from independent exposure of different sexes to novaluron were different than the control for all three exposure types; male only, female only, and both treated. The horizontal transfer experiment yielded no significant difference while the topical application of novaluron on eggs showed significantly lower egg hatch. Although novaluron has no direct toxicity to adults, the results of this study demonstrate that the delayed lethal activity of this compound reduces hatching of eggs laid by treated adults. Along with the direct ovicidal and larvicidal properties of novaluron, the delayed lethal activity provides an important contribution to the overall control seen in the field.

“…Similarly, another chitin synthesis inhibitor diflubenzuron was highly toxic to the recently laid eggs of several insect species, but had little or no effect on more mature eggs (Grosscurt 1978;Assal et al 1983;Chockalingam and Noorjahan 1984;Charmillot et al 2001). In contrast, novaluron significantly reduced viability of the European corn borer, Ostrinia nubilalis (Hubner) eggs that were close to hatching (Boiteau and Noronha 2007), but had no effect on the 0-24 h old eggs of the red flour beetle, Tribolium castaneum (Herbst) (Kostyukovsky and Trostanetsky 2006).…”

Novaluron is a chitin synthesis inhibitor (a benzoylphenyl urea) that kills larval stages and causes reversible cessation of laying viable eggs in adults of the Colorado potato beetle, Leptinotarsa decemlineata (Say). Previous studies also suggest that it has ovicidal properties, but not on all tested egg masses. We investigated if egg maturity at the time of exposure affects its susceptibility to novaluron. Novaluron application significantly reduced the hatch of eggs that were 0-24 h old at the moment of treatment, but had no effect on the eggs that were 96-120 h old. Novaluron also interfered with the development of the hatched larvae regardless of the egg age at the time of treatment, probably due to chorion feeding by neonates. Ovicidal properties of novaluron may contribute to Colorado potato beetle control, but their effect will be limited to newly laid eggs. If that window of susceptibility is missed, hatching larvae will be exposed to a fairly old novaluron residue that might be weathered down to sublethal levels. This supports the current recommendations to apply novaluron as a larvicide.Resumen Novaluron es un inhibidor de la síntesis de quitina (un benzoylphenyl urea) que mata estados larvales y causa cese reversible de la deposición de huevos viables en adultos del escarabajo de Colorado, Leptinotarsa decemlineata (Say). Estudios previos también sugieren que tiene propiedades ovicidas, pero no en todas las masas de huevos probadas. Investigamos si la madurez del huevo al tiempo de la exposición afecta su susceptibilidad al novaluron. Su aplicación redujo significativamente la eclosión de los huevos de 0 a 24 hs de edad al momento del tratamiento, pero no tuvo efecto en los de 96 a 120 hs de edad. Novaluron también interfirió con el desarrollo de la larva emergida, independientemente de la edad del huevo al momento del tratamiento, probablemente debido a la ingestión de la cubierta externa del huevo por los neonatos. Las propiedades ovicidas de novaluron pueden contribuir al control del escarabajo de Colorado, pero su efecto estará limitado a la oviposición nueva. Si se pierde esa ventana de susceptibilidad, la larva resultante estará expuesta a un residuo de novaluron bastante viejo que pudiera ser disminuido a niveles subletales por el ambiente. Esto respalda las recomendaciones actuales de aplicar novaluron como un larvicida.
