Biological features, population dynamics and harmfulness of Aphis fabae on red beet crops in Ukrainian Woodlands were specified. The degree of phytophag population on red beet of the varieties of different maturity groups and under different seeding terms was detected. The efficiency of biological agents Aktofit 0.2 % emulsifiable concentrate, Bitoksybatsylin (BTU) and insecticide Konfidor water-soluble concentrate was determined. It was detected that the agents reduced the pest population (Bitoksybatsylin (BTU) by 77.5 %, Aktofit 0.2 % emulsifiable concentrate — 77.8 %, Konfidor watersoluble concentrate — 78.7 %) and provided root crop growth by 12 %.

Black Bean Aphid

The Black bean aphid Aphis fabae Scopoli (Homoptera: Aphididae) is a serious pest of faba bean, Vicia faba L. (Fabaceae) in Algeria. The use of resistant cultivars may reduce the impact of this pest on broad bean production and at the same time reduce environmental risks and control costs. The level of resistance of fourteen cultivars of broad bean, Vicia faba was screened in the field against the main aphid pest of faba bean, the Black bean aphid, Aphis fabae Scopoli during January to April 2011 in Biskra region (in the east of Algeria). Among the cultivars tested, six cultivars (1, 9, 12, 13, 14 and 15) were the most resistant in the three counts, while three cultivars (4, 6 and 11) were showed a high susceptibility against this aphid at least once. The remainder of cultivars (3, 5, 7, 8 and 10) revealed an unsettled level of resistance. The relationship between the level of resistance and morphological characters of cultivars indicated that the resistant cultivars have a longer leaflet than the high susceptible cultivars. In the other hand, the statistical analysis showed that no significant differences on the plant height and the leaflet width in the tow category of cultivars (resistant and high susceptible).

Patterns Of Distribution

A number of biological parameters relevant to the population dynamics of Paranemonia vouliagmeniensis are discussed. The abiotic factors of the lagoon's waters are stable throughout the year. Paranemonia vouliagmeniensis populations follow different patterns of distribution (aggregated or random) in relation to human influence, and can thus become a reliable bioindicator for the lagoon.

Black Bean Aphid

Black bean aphid (Aphis fabae scop.), belongs to order Hemiptera and family Aphididae, is one of the important pests of the Fabaceae family. Beauveria bassiana is an important biocontrol agent to replace chemical insecticides. Therefore, in this research, two different varieties of broad bean with three different concentrations of B. bassiana were investigated on adults of fabae aphids under field conditions. After 3, 5, 7, and 14 days, the effect of the B. bassiana on the population of aphids was measured. The local variety was found to be more sensitive to the aphids compare with the Spain variety. In the high concentration (108 spores/ml), 80% mortality was obtained with B. bassiana in day 3 with local variety; then mortality increased after 5, 7, and 14 days of measuring the population of the adults. Mortality declined with the decrease in concentrations. The Spain variety was found to be resistance because fewer aphids were recorded compared to the local variety. In the highest concentration and day 14, mortality was 100%. The achieved results showed that B. bassiana can be used as a potential biocontrol agent for the management of black bean aphid in the fields.
