The South American native species Tuta absoluta is recognized as a tomato pest with fulminant dispersal ability in the new invaded areas. T. absoluta monitoring in all tomato-producing regions of the country is a vital step in early detection and integrated management decision-making. The aim of the study was to elucidate the interval of occurrence and population dynamics of T. absoluta in Muntenia region, respectively the vegetable basin that supply Bucharest northern markets. The paper presents the results of pest monitoring carried out in 2016, 2017, 2018 and 2019, by using pheromone-baited traps and also by visual inspection of tomato crops in various greenhouses in four localities from Bucharest surrounding area. The study provides first systematic monitored data about T. absoluta dynamics in protected tomato crops from southern Romania. Depending on year weather conditions, in the greenhouses tomato crops from the investigated area, the tomato leaf miner completed maximum 3 to 4 generations from spring to autumn and the degree of attack on tomatoes reached its maximum at the end of the second vegetation cycle. There was also noted a steady annual increase in the number of adult catches and degree of attack on tomatoes in the protected crop from analysed area.

The aim of the study was to update knowledge of the complex of harmful species that damage apple tree buds, flowers and leaves in orchards in the southern part of Romania. The pest fauna identified by visual observation and collection of infested plant material in the 2021 study, performed in 3 orchards, was represented by a total of 4 species of beetles: Phyllobius pomaceus, P. oblongus, Anthonomus pomorum (Coleoptera: Curculionidae) and Tropinota (Epicometis) hirta (Coleoptera:Scarabaeidae) and 12 species of moths: Phyllonorycter blancardella (Lepidoptera: Gracillariidae), Stigmella malella (Lepidoptera:Nepticulidae), Hyphantria cunea (Lepidoptera:Erebidae), Leucoptera malifoliella, Lyonetia clerkella (Lepidoptera: Lyonetiidae), Adoxophyes orana, Archips podanus, A. rosanus, Clepsis consimilana, Pandemis heparana, P. cerasana and Hedia nubiferana (Lepidoptera:Tortricidae). The report reveals the variations among orchards, in terms of species composition, relative abundance of common species and their importance for the region.

"The cosmopolitan aphid species Myzus persicae is a key pest of peach orchards in south and southeastern Romania. The phenomenon of resistance induced by the intensive use of insecticides is a matter of concern for farmers and protectionists, making necessary integrated measure for the control of this pest. Conservation of natural enemy’s populations is an essential component of any management system proposed for pest aphids. The aim of the study was to determine the structure of predatory insects associated with Myzus persicae populations in peach orchards. The research was carried out in three orchards from two localities from Constanta County, in peach plantations with Springcrest variety aged 7, 11 and 12 years. As a result of this study, there were determined a total of 15 predatory insect species belonging to eight systematic families: Coccinellidae, Chrysopidae, Hemerobiidae, Syrphydae, Cecidomyiidae, Panorpidae, Nabidae and Forficulidae, which naturally contribute to the reduction of the green peach aphid populations.

" This paper presents the species composition and abundance of epigeal invertebrate fauna collected from experimental pepper crops at the Vegetable Research and Development Station Buzău, Romania during 219-2020. The open field bell pepper Buzau 10 (2019) and Cantemir (2020) varieties were used in the experiment in five variants with two factors, diatomite (three doses) and bioinoculant Trichoderma asperellum Td85 strain. Diatomite was local from the Pătârlagele deposit (Buzău County) and antagonistic fungus was from the collection of microorganisms of Research and Development Institute for Plant Protection Bucharest. The fauna on the soil surface was collected using Barber traps, replaced every two weeks from June to October. The ecological parameters of abundance, dominance, constancy and ecological significance have been calculated using specific formulas. Specific attributes of the two products, diatomite and bioinoculant Trichoderma, reflected on the ecological and structural characteristics of invertebrate communities."
