Monitoring of Codling Moth (Cydia Pomonella L.) in Apple Orchards Using Two MethodsThe present studies were conducted in 1999-2001 in three apple orchards differing from each other by the system of cultivation, the type of agricultural treatments and chemical control of pests. Their purpose was to monitor codling moth (Cydia pomonellaL.) in different types of apple orchards using pheromone traps, finding out the relation between the occurrence of moths and the sum of effective temperatures as well as determining the number of wintering caterpillars of this species with the use of bands of corrugated paper. The analysis of male flight of codling moth on the basis of pheromone traps makes it possible to state the occurrence of two generations in each studied year. The maximum population of the first generation was observed in the second or third ten days of June, while that of the second generation in the first ten days of August. The moths flight began when the sum of effective temperatures was 109.2-145.2°C, and the mean diurnal temperature was 12.3-17.2°C.

AbstractIn Ontario apple orchards, the amount of synthetic codling moth (Cydia pomonella (L., 1758)) sex pheromone, E,E-8,10-dodecadien-1-ol (0.01–10.0 mg) used to bait traps significantly affected the mean total numbers of moths captured, whereas similar mean total numbers of moths were captured in traps baited with different amounts of pear-derived kairomone, ethyl (2E,4Z)-2,4-decadienoate (0.01–10.0 mg). The attractiveness of kairomone-baited traps was not increased by using greater amounts (100 and 1000 mg) of this compound. The attractiveness of the pheromone was not enhanced by the addition of kairomone. Similar patterns of adult male seasonal activity were observed when using pheromone-baited traps and kairomone-baited traps. The potential usefulness of kairomone-baited traps in the integrated management of C. pomonella in Ontario apple orchards is discussed.

Considerable Damage

Codling moth Cydia pomonella L. is a bio-aggressor that causes considerable damage in apple orchards. In Algeria, in the region of Ain-Touta, the damage caused by this pest reached 82.7% in 1998. Chemical control is most often used to repress this micro-Lepidoptere.The knowledge of the life cycle of the species and its spatio-temporal relationship with its host plant is essential in order to consider an appropriate fight against this pest. Our study focused on the bio-ecology of codling mothin two apple orchards, planted with the varieties of Dorset golden and Golden delicious, in regions of Draa Ben Khedda and Sidi Naâmanein Tizi-Ouzou wilaya (Algeria).The eggs enumeration of this micro-Lepidoptera confirms the existence of two generations in Draa Ben Khedda and three generations in Sidi Naamane.The rate of infestation caused by larvae on the fruits on trees reached a percentage of 4.6% in the Dorset golden plot, and 5.3% on the fruits fallen on the ground. In the Golden Delicious plot, the attacks on fruits present on the trees reached a percentage equal to 17.2%, whereas these attacks reached a level of 20.0% on the fruits fallen on the ground.

AbstractThe developmental rate of Frankliniella occidentalis (Pergande) was determined on cucumber Cucumis sativus cv. Sandra over a range of constant temperatures. The lower developmental threshold (LDT) and the sum of effective temperatures (SET) for the pre-imaginal development were 10.7°C and 231.1°C, respectively. The rate of population increase was assessed as the sum of effective temperatures above the lower developmental threshold by monitoring the numbers of thrips on individual leaves of cucumber under commercial greenhouse conditions. Population growth was characterized by an early stochastic phase, corresponding to pre-imaginal development of the first generation, and followed by an exponential phase starting with the second generation, the rate of which did not vary between plants. Throughout the exponential phase, the rate of population growth increased with time/age of plant. As significant damage to cucumber may occur during the exponential phase of population increase, the sum of effective temperatures of 231°C can be used to predict when damage is likely to start to occur.

The Rosy rustic moth (<I>Hydraecia micacea</I>) has been a pest of hop in Czech hop regions for a long time. It causes most severe damages in hop gardens infested by quackgrass (<I>Elytrigia repens</I>) on waterlogged<B> </B>areas. Larvae emerge from the second half of April to the middle of May. The sum of effective temperatures (SET) necessary for hatching larvae has been determined to be 78.6C over a 4-year average. Young larvae first feed on leaves of quackgrass, and later move to hop plants where they feed inside the shoots and rootstocks. Occurrence and damage are<B> </B>most frequent at the edges of hop gardens and in places with anchorages between two hop gardens. The ichneumonid wasp <I>Ichneumon sarcitorius</I> and the fly <I>Lidella thompsoni</I> are the most common parasitoids of this pest. Numbers of males caught in pheromone traps were very low. More males were trapped near hop gardens typical for repeated harmful occurrence of the rosy rustic moth. Females trapped in a light trap from the second half of August to the last decade of September had already full-developed eggs in their ovaries.

AbstractPheromone traps were deployed in Borsod-Abaúj-Zemplén County (Hungary) between 1982 and 1988, in 1990 and also between 1993 and 2013. These traps attracted 8 Microlepidoptera species:Phyllonorycter blancardella, P. corylifoliella,Anarsia lineatella,Eupoecilia ambiguella,Lobesia botrana,Grapholita funebrana,G. molestaandCydia pomonella. We examined the trapping data of these species in the context of lunar phases and polarized moonlight. Catches of the European Vine Moth (Lobesia botrana) and the Codling Moth (Cydia pomonella) were higher in the First Quarter, whereas catches of Peach Twig Borer (Anarsia lineatella), Vine Moth (Eupoecilia ambiguella), Plum Fruit Moth (Grapholita funebrana) and Oriental Fruit Moth (Grapholita molesta) were larger in the Last Quarter. Catches of the other two species, the Spotted Tentiform Leafminer (Phyllonorycter blancardella) and Hawthorn Red Midget Moth (P. corylifoliella), were higher in both the First and Last Quarters. When using pheromone traps, insects do not fly to a light source, so moonlight does not modify either the catching distance or flight activity. However, at high levels of polarized moonlight, pheromone trap catches will increase, as in the case of light-trap catches. The results are comprehensible when one considers that the target species can fly both during the daytime and also at night.

In this paper is reported the evaluation of biological efficacy of two minor components that was added to the basic sex pheromone component Cydia pomonella L., E8, E10-C12-OH. The use of minor component- C.M.-1 of increasing concentrations in binary mixture compositions with the basic sex phe-romone component of codling moth on pheromone-impregnated rubber septa in delta pheromone traps has shown an increased effectiveness by 56-62% in field trials on apple orchard. At the same time, the number of males caught in delta pheromone traps where were used minor component - C.M.-2 in binary mixture compositions increased by 29-35%. Auxiliary research is still needed.
