The researches were made during 1992-2001. There were collected 10704 specimens of carabidaes (Coleoptera- Carabidae). The species with the largest number of collected specimens were: Pseudophonus rufi pes, Harpalus distinguendus, Pseudophonus griseus, Brachynus explodens, Brachynus crepitans and Amara familiaris

OBSERVATIONS ON THE STRUCTURE, DYNAMICS AND ABUNDANCE OF SPECIES OF EPIGEE COLEOPTERS IN ORCHARDS APPLE HAVING THE RANGE BETWEEN ROWS WITH HERBED BANDS

The observations were made in 2017 in a orchars apple plantation in Delesti – Vaslui area with the inter-line spacing in the form of grass strips, with the species Bromus inermis Leyss.To collect the material, in 2017 it was used Barber soil traps which were installed in the orchard, on the grassy interval between the previously mentioned species. During the vegetation period, from April to September, the insects were also collected from the traps, retaining and determining the beetle species.The material was collected periodically, at intervals of about 10-15 days, in total, 10 harvests. Among the collected species we mention: Harpalus calceatus, Dermestes laniarius, Harpalus distinguendus, Anysodactilus signatus, Otiorrhynchus porcatus, Aphthona euphorbiae, Malachius bipustulatus etc

CONTRIBUTIONS TO THE KNOWLEDGE OF THE EPIGEE COLEOPTEROPHUNA FROM APPLE TREE ORCHARDS WITH GRASSED BANDS BETWEEN ROWS SOWED WITH GUIDES (LOTUS CORNICULATUS)

In preparing this work, the material collected with the help of the soil traps type BARBER, of the "wet" type, was used in an apple tree orchards  in the Deleşti area, Vaslui county. The traps operated from May to September inclusive.The material from the traps was harvested periodically, throughout the vegetation period, depending on the pedoclimatic conditions, generally at intervals of 10-12 days.At each of the 10 collections of the material, the liquid in the trap was replaced. The material was then determined, identifying the species of beetles.The most frequently collected and the most numerous species are presented below: Harpalus calceatus (75 specimens), Harpalus pubescens (49 specimens), Anysodactilus binotatus (48 specimens), Harpalus tenebrosus (43 specimens)

DYNAMICS OF THE APPEARANCE THE PEST DIABROTICA VIRGIFERA VIRGIFERA, IN THE MAIZE CROPS OF NEAMŢ COUNTRY, UNDER THE CONDITIONS OF 2019

Research on the dynamics of the appearance of Diabrotica virgifera virgifera was made in the frame of a farmland cultivated with maize in Neamt county. The biological material collected using sticky yellow traps during the year 2019 from June to August. The variants and repetitions of the experience were organized according to the mode of protection of culture and according to the treatment applied, and thus resulted in three variants as follows:Variant 1 - untreated maize; Variant 2 - ground treatment with granulated insecticide FORCE G 1.5; Variant 3 - treatment of the seed with Seedoprid 600 FS.During the entire period of observation, a total of 5313 adult specimens of Diabrotica virgifera virgifera were collected, where the first alert of the adult was made on 12 June, and its last registration was on 16 August

DYNAMICS OF THE APPEARANCE THE DIABROTICA VIRGIFERA VIRGIFERA, IN THE CORN CROPS OF NEAMŢ COUNTY, UNDER THE CONDITIONS OF 2020 IN DIFFEREND TILLAGE SYSTEM

In order to establish the optimal moment of carrying out the treatments for the control of the adults, the dynamics of the appearance for Diabrotica virgifera virgifera is very important step in warning of treatments and their effectiveness.The research was carried out, in the corn cultivars from Neamt County. The biological material collected using sticky yellow traps during the year 2020 from June to September.The experience and randomization were organized according to the mode of protection of culture and according to the treatment applied, and thus resulted in three variants as follows three variants : variant 1 - no tillage work system, variant 2, minimum tillage work system and variant 3 , conventional tillage work system. In all variants the soil have was treated with granulated FORCE G 1.5 insecticide, active ingredient 1.5%, (Syngenta) at a dose of 15 kg ha.During the entire period of observation, a total of 5810 adult specimens of Diabrotica virgifera virgifera were collected, where the first alert of the adult was made on 15  June, and its last registration was on 15 September

Observations on the existing carbide species in the apple orchards

In this paper new contributions are made to the knowledge of the species of carabids in a fruit tree apple of Delesti in the Vaslui country. The material was collected from May to September throughout the research period, using Barber traps. From the biological material collected, all species collected have been listed and determined and only the species belonging to the Carabidae family have been selected afterwards. In the period of the observations were collected throughout 1573 specimens of harmful and useful insects, so 795 were collected in 2018 for 11 species, and 778 were collected in 2019 for 33 species. Analysis of the collected material was found the most frequevence species was: Carabus coriaceus L., Pseudophonus rufipes Mull., Opatrum sabulosum L., Phyllotreta vittula F., Phyllotreta nemorum L., Formicomus pedestri Anysodactilus binotatus, Harpalus distinguendus, Harpalus calceatus, Harpalus tenebrosus, Harpalus griseus, Amara crenata, Harpalus tardus, Metabletus truncatelus, Amara aenea si Harpalus pubescens

Observations regarding the structure and dynamics of the existing epigeus entomofauna in the apple fruit tree plantations

Observations on epigeus entomofauna were made during 2019 in a apple fruit tree plantation owned by SC Loturi Service SRL, Delesti, Vaslui County. The harvesting of the biological material was done with soil traps type Barber and with the beeting method, from May to August inclusive. The collected material was cleaned from plant debris and then prepared for identification at order of insects, and in the coleoptera species these were determined to species level. The analysis of the collected material shows that the specimens collected belong to the Hexapoda class. Most of the specimens collected belong to the Insecta class. The most common species were: Dermestes laniarius, Anysodactilus binotatus, Harpalus distinguendus, Cantharis fusca, Tachyusa coarctata, Otiorhynchus pinastri, Amara aenea and Microlestes minutulus

Observaţii asupra entomofaunei din culturile de grâu colectată la capcanele de sol

The increase grain production is possible through the application of technology that involves the use of varieties with high yield, soil fertilization to provision according to their requirements, full mechanization of work and measures to prevent and combat specific pests and weeds. Regarding pests of grain crops grasses, they can cause annual havoc 13.8% compared to 11.6% produced by pathogens and weeds due to 9.5%. This paper presents the research on the epigenous entomofauna of wheat crops in 2016, in Focsani area used the traps type Barber and collecting biological material was conducted from May to July. The collection of the biological material was performed periodically on the following dates: 23.05; 07.06; 23.06; 07.07 using 18 traps belonging to the three experimental variants: •Variant 1 - wheat after sunflower; • Variant 2 - wheat after wheat; • Variant 3 - wheat after rape.The most commonly species found in this period are following the order: Coleoptera, Hymenoptera, Orthoptera, Heteroptera, Diptera, Colembolla etc. They were collected in addition to insects, and species belonging to the Crustacea class with the Isopods order, and the Arachnida class with the Araneae order

NEW CONTRIBUTIONS TO THE KNOWLEDGE OF THE MORPHOLOGY, ECOLOGY AND DAMAGE CAUSED BY MINING MOTH CHESTNUT (CAMERARIA ORHIDELLA DESCHKA & DIMIC) IN THE HUSI - VASLUI AREAL CONDITIONS FROM EASTERN OF ROMANIA

During the research were made observations about morphology, ecology and damage the chestnut trees in the Husi-Vaslui area by chestnut leaves mining moth (Cameraria orhidella Deschka & Dimic).The harmful specie is a Lepidoptera that belongs to the Gracillariidae family, who presented a low degree of resistance to unkind ecological conditions, but still developed three generations per year which caused heavy damages in the crow of the chestnut trees by consuming the palisade tissue, producing mines on the upper face of the leaves
