Töö eesmärgiks on välja selgitada kuue põldoa sordi vastuvõtlikkus putukkahjurite ja –
kasurite. Töös on seatud hüpoteesideks, et põldoa sordid on erineva atraktiivsusega
lehetäidele ja teistele kahjuritele ning sort mõjutab kasurite ja kahjurite liigilist koosseisu ja
arvukust.
Hüpoteesi kinnitamiseks või ümberlükkamiseks viidi 2019. aastal Eerikal (Tartumaa) läbi
põldkatse, milleshinnati 6 põldoasordi atraktiivsust kasuritele ja kahjuritele. Katses oli 6
kordust ning oli ülesehitatud juhusliku valiku alusel. Püügiks rakendati raputusmeetotitt ja
kasutati aspiraatorit. Statistilised analüüsid teostati programmiga Statistica 13,2. Põldoa
sortide mõju leiti ühefaktorilise dispersioonanalüüsi (ANOVA) abil, variantide omavahelisel
võrdlemisel kasutati Tukey HSD ja Fisher LSD posthoc teste (p < 0,05).
Töö käigus leidsid hüpoteesid kinnitust. Lehetäid ja ripslased eelistasid statistiliselt
usaldusväärset katses kasvatatud põldoasorti ’Helbi’. Oa-teramardikad eelistasid
katseperioodil enim sorte ’Helbi’ ja ’White Windsor’, kuid teradel olevaid kahjustusi
vaadeldes esines sordil ’Lynx’ 80% kahjustusi. Lepatriinude ja lehetäide vahel on keskmise
tugevusega positiivne seos (r= 0,59).
The aim of the work is to identify the susceptibility of six faba bean varieties to insect pests and to the beneficial incects. In the work, hypotheses have been set that the varieties of apron are of different attractiveness to the aphis and other pests, and the variety affects the species composition and abundance of the beneficial insects and pests. To confirm or reject the hypothesis was year 2019 in Eerika (Tartumaa) through the field test, the attractiveness of 6 faba bean varieties was evaluated for thebeneficial and pest insects. The test had 6 replays and was constructed on a random basis. A shaking measure was applied to the fishing operation and an azpirator was used. Statistical analyses were conducted with the Statistica 13.2 programme. The impact of the apron varieties was found using a single-factor dispersion analysis (ANOVA), the use of Tukey HSD and Fisher LSD posthoc tests (p < 0.05) were used to compare the variants. During the work, hypotheses were confirmed. The aphis and thrips did favour statistically reliable variable ’Helbi’, broad bean beetle preferred the most varieties 'Helbi' and 'White Windsor' during the trial period, but the damage to the grain was seen in the 80% damage by 'Lynx'. There is a positive relationship (r = 0,59) of the mean strength between the ladybirds and the aphids
