“…In The Netherlands one to four sprayings with broad spectrum insecticides are carried out, especially against A. orana. If the use of these chemicals is discontinued, as required for integrated pest management (IPM) in apple orchards, leafroller species other than A. orana may become numerous (Gruys, 1982;Ankersmit et al, 1977;de Jong & Gruys, 1975). The question arised whether a mixed population of different leafroller species could be controlled by Insect Growth Regulators (IGR) with juvenile hormone activity.…”

The Insect Growth Regulators with juvenile hormone activity, fenoxycarb and epofenonane, were applied either to separate apple trees, which were artificially inoculated with Adoxophyes orana (F.v.R.) and Pandemis heparana (Denn. & Schiff.), or in apple orchards infested with several naturally occurring leafroller species. The susceptibility of leafrollers to fenoxycarb was very high and the foliar residue remained active for at least 4 weeks. The leafroller parasites Apanteles ater (Ratzeburg) and Colpoclypeus florus (Walker), during their development in or on the host, appeared to be less susceptible to both epofenonane and fenoxycarb than the host itself. RÉSUMÉ Essais contre certaines tordeuses de l'épofénonane et du fěnoxycarbe (régulateurs de croissance des insectes), et actions sur quelques uns de leurs parasites Le fěnoxycarbe et l'épofénonane (régulateurs de croissance des insectes) ont été appliqués soit sur des pommiers isolés, artificiellement inoculés avec Adoxophyes orana (F.v.R.) et avec Pandemis hep‐arana (Denn und Schiff), soit dans des vergers, contaminés naturellement par plusieurs espèces de tordeuses. Sur les arbres isolés, le fénoxycarbe appliqué à raison de 5 g de composé actif/100 l et l'épofénonane de 5 ml de composé actif/100 l, affectent la morphogenèse d'A. orana et P. heparana. Le fénoxycarbe agit sur A. orana měme à une concentration de 0,5 g de composé actif/100 l. Dans les vergers, la vaporisation d'épofénonane (750 ml de composé actif/100 l) et de fénoxycarbe (75–150 g de composé actif/100 l) a déformé sévèrement les larves d'A. orana, d'Archips podana (Sc.), de Spilonota ocellana (F.) de P. heparana et d'Archips rosana (L.). Les résidus foliaires actifs ont persisté au moins 4 semaines, comme l'ont montré les effets morphogénétiques observés chez A. orana et P. heparana. Au cours de leur développement, sur ou à l'intérieur de l'hǒte, les parasites de tordeuses Apanteles ater (Ratzeburg) et Colpoclypeus florus (Walker), sont moins sensibles à l'épofénonane et au fénoxycarbe que l'hǒte lui‐měme. Des expériences ultérieures à plus grande échelle sont nécessaires pour évaluer l'utilisation des régulateurs de croissance des insectes contre les tordeuses dans le contrǒle intégré des vergers.

“…Development at constant temperatures on artijcial medium: Egg batches of 0. incerta were obtained in the same way as in the previous experiments. Just after emergence, larvae were placed individually in glass tubes with artificial medium enriched with apple leaf (ANKERSMIT, 1975), at five temperatures: 10, 14, 17.5, 20 and 27.5"C a t photo phase 16 hlight : 8 h dark. Each experiment started with 100 larvae.…”

Three Orthosia species were studied to forecast larval emergence and development and to find out the optimal moments for monitoring and control. The duration of embryonic and larval development of Orthosia incerta and Orthosia stabiliz was determined at various constant temperatures, and validated in field experiments. Embryonic development of Orthosia gothica was followed in the field. No significant differences between embryonic development of the species under study were observed. The estimated heat sum for embryonic development is 72 degree days above a developmental threshold of 7.0"C. Differences in development of the first larval stage depending on the quality of the substrate were found for 0. incerta. Stage one of this species developed faster on artificial food than on fresh apple leaves, but total larval development rates of the species observed showed hardly any difference. The regression equation Y = 0.0017 x 7'-0.0045 gives a good description of the total larval development rate (Ll-pupa) for both species. The larval development rates were implemented in an age-structured phenological computer model INSIM. Results of simulations were in close agreement with field observations. Opportunities for use of these data in practice are discussed.
