of some Methods for Detecting, Forecasting and Control of Noctuide Defoliator Species Present in Oak Forests of Northwestern Transylvania

Abstract. The Noctuidae Family (ord. Lepidoptera, fam. Noctuidae) includes a large number of species, butterflies with different class, with very variable appearance, making it difficult to identify species. The activity of most species is nocturnal, rarely daytime. Research has considered the detection and understanding of Noctuidae species (moth), which together defoliated best known and most frequent cause of quercus species damage in these stands. The research sought to determine the most appropriate method for detecting the stages of caterpillar, pupa and butterfly. Laboratory work consisted of literature documenting both written form and electronic manufacturing equipment necessary collection of biological material (light trap, trap type Barber, sieve to pupa etc.), analysis and conservation of biological material collected (stalk, larvae, pupa, butterfly), interpreting the results. Field work was carried out betwee
