Impact Evaluation of Some Crops Integrated Pest Management Systems on Microorganisms and Soil Arthropods

Fly ash constitutes above 70% of the whole amount of residues formed in power plants through combustion of coal. The addition of Fly ash in soil improves or changes various physical, chemical and biological characteristics of soil. Fly ash is used for the improvement of the soil texture, water holding capability, density, bulk density, porosity etc. by using in different ratio with soil. For the growth of plant and crop yield fly ash is used as ameliorate in acidic soils. An experiment was conducted during the years 2015-17 adjacent to Yamuna River in the south of Allahabad city, India to find the impact of flyash on Soil physical Properties under Sunflower-Spinach-Sunflower Crop Rotation System. Findings of experiment reveal that the percentages of porosity, soil water holding capacity were increased while soil bulk density, soil particle density, soil solid space decreased as the dose of flyash increases under both cropping system even though after harvesting of crops there is slight decrease in these value.

Diversity of Click Beetle Associated with Maize and Sunflower Crops from South and SouthEastern Romania

The present study aimed to evaluate the structure of the click beetle (Coleoptera:Elateridae) fauna associated with corn and sunflower crops in the south and southeast of Romania, based on the specimens collected during 5 years (2015-2019), in 25 plots from 9 localities belonging to 3 counties. The analysed material included a number of over 3000 specimens and the results showed a significantly high click beetles diversity represented by 16 species and a variety assigned to 9 genera and 8 subfamilies. At regional scale, dominant species were found: Agriotes ustulatus (22.15%), Drasterius bimaculatus (19.17%), Agriotes sputator (14.4%), Agriotes obscurus (11.45%), Agriotes lineatus (9.72%) and Selatosomus latus (8.84%). The analysis of the data highlights the similarity between the Elateridae communities in Călăraşi and Ialomița Counties, where the dominant species were A. ustulatus and A. sputator, and their net difference with the click-beetles communities in Constanța County, where the dominant species were D. bimaculatus, S. latus and A. sputator. The obtained results represent the starting point of a database on the wireworm fauna associated with maize and sunflower crops in Southern Romania, and bring basic information's needed for further development of Integrated Pest Management.

Evaluation of Beauveria bassiana and Beauveria pseudobassiana Against Tanymecus dilaticollis

In this article we report result of evaluation of native strains of entomopathogenic fungus Beauveria bassiana (Bals.) Vuill. (Deuteromicotina: Hyphomycetes) and B. pseudobassiana Rehner et Humber against Tanymecus dilaticollis (Curculionidae: Entiminae) both in laboratory and field. In laboratory assay, two different strains of B. bassiana and one strain of B. pseudobassiana (BbLy) were applied on insects as 1×10 8 conidia/ml aqueous suspensions. The pure ATCC 74040 commercial strain of B. bassiana and the commercial mycoinsecticide based on this strain (Naturalis) were included in the laboratory assay for comparison. Adult mortalities were recorded daily, 14 days post-exposure. All the fungal strains have been shown to be pathogenic to T. dilaticollis. The B. bassiana strain (BbTd1) and the B. pseudobassiana strain (BbLy) were effective against adults of T. dilaticollis and comparable in percentage of mycosis and virulence to the B. bassiana strain ATCC 74040. The commercial product Naturalis was superior to the tested fungal strains killing the insects within a day. In the field, the strains BbTd1 and BbLy applied as conidia multiplied on barley grains (1×10 9 /g d.w) in the soil did not affect the T. dilaticollis density in maize crop.

Study on Monitoring and Combating the Attack of Tuta Absoluta on Tomatoes Cultivated in Protected Spaces in South Romania

Tuta absoluta is an extremely dangerous polyphagous insect. It belongs to the Gelechiidae family, Lepidoptera order. The pest is a small butterfly (moth), 5-7 mm long, brown with shades of dark gray. The larva is white-green, with a black head and a brown pupa. It has 12 generations per year. An adult female can have up to 250 eggs during her lifetime. The life cycle is completed in 30-40 days, but largely dependent on environmental conditions. It has 4 larval stages, wintering as an egg, pupa or adult. Moths are more active during the night, during the day being hidden among the leaves. Starting with 2020, in some protected spaces from well-known vegetable basins for growing tomatoes in South Romania, a study was initiated on monitoring the attack of Tuta absoluta. Preliminary results show that the pest is extremely harmful (sometimes the damage to tomato cr...

ENTOMOPATHOGENIC EFFECT OF SOME Beauveria ISOLATES ON THE TOMATO LEAF MINER Tuta absoluta (MEYRICK) (LEPIDOPTERA: GELECHIIDAE) LARVAE UNDER LABORATORY CONDITIONS

The fungal treatments were done with concentrations of 1 × 10 5 , 1 x 10 7 and 1 x 10 9 conidia ml-1.. Seven days after treatment application, both Beauveria isolates induced a Tuta absoluta mortality above 80%, the best results being registered in case of combination between the use of B. pseudobassiana isolate at a concentration of 1 x 10 7 conidia ml-1 and the predator Arma custos. No side-effects on natural enemies used in combination indicate these isolates as promising alternative for Tuta absoluta control.
