Ovalisia festiva (Linnaeus, 1767), previously considered a very rare and localised (accidental) species in Eastern Europe (Hungary, Romania), is recorded as a real pest for Cupressaceae in the Romanian Plain − the Easternmost site, out of the species’ previously known range. In comparison with the annual life cycle of the species in the Mediterranean region, in Romania the adults emerged between the second and the eighth year after the trees were planted, causing an attack of over 50% per cultivar. New data on intraspecific variability, distribution, and duration of the life cycle of this jewel beetle in Romania are presented.

In our experiments we have identified and isolated the pathogen Botrytis cinerea Pers. from geranium plants, we have inoculated it on three types of culture media (PDA, Czapek-agar, MA) and studied its morphological and cultural characteristics. The results obtained consist in differences in the morphology, number and distribution of the sclerotia and the dimensions of the conidia. The isolates taken under study showed a great phenotypic diversity influenced by the host plant and by the culture medium where they was grown.

Ladybirds (Coccinellidae) are a popular, widely recognized and highly regarded insect group due to their bright color and role in controlling insect pests. Worldwide nearly 6000 species are known. From systematic point of view, ladybeetles belonging to Class Insecta, Subclass Pterygota, Order Coleoptera, Suborder Polyphaga, Superfamily Cucujoidea anf Family Coccinellidae. Coccinellids are of interest and importance in agriculture and forestry, since adults and larvae of most species are predators of herbivorous pests such aphids, psyllids, mealy bugs and scale insects. The aim of this research regarding coccinellid beetles was to explore, identify and also characterize the coccinellid fauna of the Banat region (Romania). The coccinellid beetles were collected from March 2013 to September 2014 from 4 localities at different altitudes in the Banat region. Samples were collected at weekly interval from a wide variety of habitats: agricultural land, gardens and parks, both on herbaceous and woody essences. In this study a total of 15 species belonging to 11 genera and 3 subfamilies were identified. In the investigated habitats from the entomofaunistic point of view, the coccinelid species identified were as follows:

Lately, Diabrotica virgifera virgifera Le Conte adults (western corn rootworm) (Coleoptera: Chrysomelidae) extended the range of host plants and also the spreading area in Romania. Though, until recently it was associated only with corn plant (it highlighted the research in Europe) today we can say that this invasive insect, in adult stage, became oligophagous. The current state of research in the ield, somewhat restrained, outlines the monitoring aspects of morphology, biology, control and less at plant atractivity. This is the main reason in addressing current topics. Also, if we want to answer the question is Diabrotica virgifera virgifera still considered a dangerous pest from crops of Romania? the answer is de initely positive. The research took place over the course of tho years of study 2011 and 2012. In our studies we used observation cages type I and II (small cages and high cages). Thus for the evaluation of trophic preferences were achieved through the determination of frequency and intensity of attacks on various plants. In the experimental covered setting is obvious attraction towards other than corn comparative with uncovered setting. By far, the preferred were plants from Cucurbitaceae and Leguminosae. According to the observations made on the leaves with the highest average attack occurred at the plants of melon, soybean and beans. The damage done by insects on lowers have highlighted orientation towards plants of sun lower, cucumber and melon. Between variants down to the various plant species in relation to the total number of leaves, lowers, leaves and lowers attacked. Actually, this species invaded the corn crops in western, southern counties, the Nordic and central Romania and damaged few crops. But we supposed that in follow soon will be present throughout the country and the attractiveness of the new plants will grow.

Diabrotica virgifera virgifera Le Conte (Coleoptera:Chrysomelidae), is an invasive pest in corn crops, known as western corn rootworm. For this, serious measures were taken to limit the spread; however it continued to expand and adapt to new areas. One of the causes responsible for invading is capacity of adapting to abiotic and biotic factors in the new habitat. Having in mind the orientation for adults and especially for flowering plants pollen we wanted to see if behavior of Diabrotica from a corn crop, at a time, is influenced by the presence and diversity of weeds. Observations were made during year of 2014, in July and August, in a place in western Romania. It was chased feeding behavior toward both corn plant and weed and the other hand, the level of population was observed. In our study we found that adults are attracted to flowers weeds; they found on much greater numbers in corn plot with weed abundant comparative the plot without weeds. Females predominated in corn crop with different weed species present.
