The codling moth (CM), Cydia pomonella (L.), causes heavy damage in Bulgarian apple orchards. Conventionally treated orchards, were monitored in this study. In spite of numerous chemical treatments, these orchards showed increasing flight densities of CM moths, growing populations of hibernating larvae and rising fruit damage rates. Thus, the control of CM by conventional spraying programmes became ineffective, apparently due to the development of resistance to insecticides. Products based on the Cydia pomonella granulosis virus (CpGV), such as Madex®, may provide alternative control tools that can be applied with other approaches, for a sustainable control strategy. The trials were carried out in Central-South and South-East Bulgaria, in 2006-2010. Four treatments of Madex® against the first generation, and six treatments against the second generation kept the fruit damage and population density of CM at a low level. Based on the obtained results, different control strategies have been suggested, depending on the initial CM pressure in a particular orchard. Madex® may be a promising alternative to traditional programmes of CM control. Its dose, however, should be adjusted to the initial CM population density. Also, at a high or moderate CM population density Madex® applications should be combined with MD to avoid resistance of CM to granulovirus. At the peak of CM hatching, additional chemical treatments may be sometimes necessary. Such treatments include using insecticides which are still effective against CM.

Studies on species composition of migratory aphids with the use of Johnsons aspirator were carried out in the Agricultural Experimental Station Winna Góra in 2002–2009. The results of performed research revealed the presence of 109 aphid species. Data on their occurrence frequency showed that most numerous species were cereal aphids and accounted for 60% of all species. The most frequent cereal aphid were Rhopalosiphum padi and Sitobion avenae.

The leopard moth borer, Zeuzera pyrina L., is a cossid moth whose larvae bore into twigs, branches and trunks of various woody species, weakening and sometimes killing trees or shrubs. Recently it caused serious losses of apple trees in Bulgaria. In a three-year-old non-protected apple orchard in the Plovdiv region more than 30% of trees perished due to damage by this pest. In the nursery and in commercial orchards up to 5% of branches were injured. Main damage was observed in August and September. Both cossids, Zeuzera pyrina and Cossus cossus, damaged 15–20% of the stems in old commercial orchards and more than 60–70% in orchards without regular plant protection. In this study flight dynamics of Z. pyrina was monitored by two types of pheromone traps: Pherocon (Trécé, USA) – traps with sticky changeable bottom and Mastrap (Isagro, Italy) – dry funnel traps. The second type was more effective. Flight of moths lasted from mid-June to the beginning of September. Pheromone traps may be helpful in IPM systems, for signalling optimal time for spraying against this pest. Further studies are needed to determine correlation between the catches in pheromone traps and appearance of injuries.

In the years 2007–2009, trials on control of codling moth (CM), Cydia pomonella (L.), were carried out in apple orchards of South-East Bulgaria, where the pressure of the pest was very high. Mating disruption with Isomate C plus dispensers was applied in combination with sprays of the virus product Madex®. With a single installation of Isomate C plus dispensers per season + 4 treatments of Madex® at 100 ml per ha against the first and 6 treatments against the second generation, fruit damage at harvest and population density of codling moth were kept at a low level. At the same time fruit damage and population density of the pest, as estimated by the hibernating CM larvae population, was very high in the conventionally treated orchard serving as a reference. Using Isomate C plus dispensers and the baculovirus product Madex® may be a promising alternative to traditional programmes trying to control high initial infestation of codling moth. For Bulgaria, the combined tested strategies of mating disruption and virus control are suggested for control of codling moth in the orchards with CM population density of more than 3 larvae per tree or more than 5% fruit damage in the previous year.

The bird cherry-oat aphid (Rhopalosiphum padi L.) development on primary host (Prunus padus L.) was studied in Poznan in 2007–2008. First fundatrices of R. padi were observed already on the bird cherry in March in both years. The largest condensation of population was observed in May. At the second decade of May numerous winged morphs were formed and spring migration into the secondary hosts started. Re-emigrants in September were observed and the oviparae and males in second decade of October gave birth. In spring observations fertilized eggs (from which aphids hatched) made up 89% and 81% respectively. The meeting of factors inducing the formation of individual morphs of R. padi and the deadlines of the migration on host-plants has a special meaning in the aspect of transfer of viruses by the anholocyclic forms of this species.

The aim of the study was to determine the level of threat by currant clearwing moth to black currant plantations in the vicinity of Lublin. Moth catches were performed using deltoid pheromone traps set, and the cane cutting methods were also used. Moths’ flight started at the end of May and lasted up to the first days of August. The flight dynamics was diversified on the particular plantations. The males’ catches and the cut shoots analysis showed that the economics threshold level was exceeded. The control of currant clearwing should be performed both on horticultural farms and amateur cultivations.
