The paper presents the results of studies of the seven-spotted beetle ( Coccinella septempunctata L.) life cycle, which has 2 generations in the climatic zone of southern Russia. The main stages of the life cycle are the emergence of imago from winter diapause, the first generation from egg to imago, the second generation from egg to imago, the care of adults for wintering. The eating behavior of coccinellid was studied at each stage of the life cycle, which showed the presence of a small herbivorous period (phytophagous beetles), most of the cycle of the beetles had a predatory lifestyle (entomophage beetles). Experiments in the natural and artificial conditions of studying the nutrition of a seven-point beetle showed that adult beetles were more effective in consuming aphids than the larvae. It was also established that in the natural environment, the degree of palatability, both in the larva and in the imago, was directly dependent on the density of the aphids: as the aphid decreased, the feeding intensity of the beetles decreased. To increase the efficiency of aphid consumption, the joint content of two predatory beetles in the imago stage was used: a seven-spotted beetle ( Coccinella septempunctata L.) and ground beetle ( Tomocarabus bessarabicus concretus Fischer von Waldheim). With such simultaneous use (polyculture), a synergistic effect was observed in their consumption of rosan aphid ( Macrosiphum rosae L.).

The aphid-transmitted Moroccan watermelon mosaic virus (MWMV; Potyvirus, Potyviridae) is an emerging pathogen in cucurbit crops in the Mediterranean basin but information on its transmitting vector species is limited. This study aimed to record the competence of 22 species of the Greek aphid fauna to vector MWMV. Timed-probe transmission experiments and arena tests were performed using laboratory colonies of aphid species abundant in field surveys; less common species were tested as apterous individuals collected directly from field plants in mass-inoculation (nonpersistent) tests. Depending on the test, aphids were tested in cohorts of 10 or 20 individuals on zucchini (Cucurbita pepo L.) plants and the frequency of transmission was calculated for a single aphid. Among 12 species tested in timed-probe transmission tests, Myzus persicae nicotianae (74.0%) appeared to be the most efficient vector, followed by M. persicae (48.0%), Aphis gossypii (11.8%), an unidentified Aphis sp. (11.8%), and A. spiraecola (11.0%). Alatae of nine species tested in arena tests transmitted the virus in rates varying from 0.7 to 53.6%; M. persicae was the most efficient species in virus spread. In mass-inoculation tests, the probability that apterae of 12 aphid species collected from field plants transmitted MWMV fluctuated from 0.3 to 5.3%. No transmission was obtained by Brevicoryne brassicae. The following species are reported as new vectors of MWMV: A. fabae, A. nerii, A. spiraephaga, A. umbrella, Capitophorus eleaegni, Dysaphis (Pomaphis) pyri, Macrosiphoniella sanborni, Macrosiphum rosae, Myzocallis castanicola, Myzus persicae nicotianae, M. cerasi, M. varians, Phorodon humuli, Ovatus crataegarius, Takecallis arundicolens (first report in Greece), Uroleucon sonchi, and U. (Uromelan) aeneum. These results contribute to a better understanding of MWMV epidemiology.

Alfalfa is known to be an important reservoir harboring natural enemies. The reduction in insecticide sprayings in recent years has allowed us to study the coccinellid species complex in this crop and the relationship between these predators and aphids. Alfalfa was sampled by sweep-netting throughout its productive period in several commercial stands each year between 2010 and 2021. The numbers and species of aphids and coccinellids were recorded. Sixteen coccinellid species were found. Coccinella septempunctata and Hippodamia variegata were, by far, the most prevalent species, with the former dominating during the first and second intercuts, whereas the latter dominated from the third to the fifth intercut. Acyrthosiphon pisum and Therioaphis trifolii were the most abundant aphid species, peaking in the second and fourth intercuts, respectively. Positive correlations were found between the abundance of C. septempunctata and A. pisum at the second intercut, between H. variegata and T. trifolii at the fourth intercut, and between H. variegata and the total number of aphids in the fifth intercut. This study helps to increase the knowledge on the predator–prey relationships of this crop and allows for designing strategies of conservation biological control against aphids.
