“…For this reason, the cultivated areas increase year by year, without respecting the technological recommendations of crop rotation, a fact that has led to an increase in the number of pests that attack corn ecosystems. Researchers state that with the intensification of agriculture, conditions have become very favorable for the development of certain pest species (Trotus 2011). A good knowledge of populations, species, their number and diversity gives us a lot of information about the stability of that agrosystem.…”

Within this station, three experimental variants were initiated that targeted the preceding culture. Therefore, the variants studied were: V1 maize in monoculture; V2 corn after sunflower; V3 corn after wheat. Barber-type soil traps were used to collect biological material, they worked continuously from April to July 2021, where a number of 5 collections were made for each variant. Barber traps consist of plastic containers of approx. 10-12 centimeters high and about 8-10 centimeters in diameter in which I used a salt solution (NaCl) with a concentration of about 20% as fixing liquid. Six traps were used for each experimental variant. Samples were collected at 12-15 day intervals when we changed the fixative – saline solution, replenished or, if necessary, replaced. The collected species were cleaned of all plant remains, other impurities, and then the coleoptera species were selected separately, and with the help of determinants they were identified. The structure, dynamics and abundance of coleopteran species were then determined according to each experimental variant, and the most frequently collected were: Tanymecus dilaticollis, Epicometis hirta, Coccinela 7- punctata, Harpalus calceatus, Harpalus distinguendus Formіcomus pedestrіs, Phyllotreta vittula, Opatrum sabulosum and Pentodonidiota.

“…The attacked strains are easily broken, the plants fall to the ground and the mechanized harvesting of the crops is difficult, resulting in important production losses (Bărbulescu et al, 2000;Balachowski et al, 1972;Camprag, 1973;Perju et al, 1983;Perju et al, 1993;Popov, 2002Popov, , 2003Popov, , 2004Trotuş, 2007;Trotuş et al, 2002;Trotuş et al, 2015Trotuş et al, , 2017Georgescu et al, 2013).…”

Pests are a considerable limiting factor in the production of corn crop. Their knowledge, but also the moment of occurrence and evolution in a certain area, is of particular importance in establishing prevention and control measures in order to limit the population under PED but also the harvest losses. Ostrinia nubilalis Hbn. species was present and caused damage to the maize crop from the Central part of Moldova, for which reason observations and determinations were made regarding the evolution of the species, the mode and the magnitude of the attack. Observations and determinations made at the Agricultural Research and Development Station Secuieni, during 1993-2017 have demonstrated that Ostrinia nubilalis Hbn. species is characterized as an abundant insect for the studied area, being present in maize, in all 25 years studied. The total number of adults collected in the light trap was of 8290 specimens, the highest catches per trap of 2818 specimens were recorded between 1993 and 1997 (first stage), followed by 1690 and 1683 specimens in stage II (1998-2002) and III (2003-2007), 1237 specimens in stage V (2013-2017), and the lowest number of 862 specimens/trap was recorded in stage IV (2008-2012). Based on the data obtained by collecting the insect by means of the light trap, the variability coefficient for the central area of Moldova was calculated and the flight curve made by the adults of the species Ostrinia nubilalis Hbn. was established.
