Abstract This work examined the impact on productivity of the cultivation system of perennial legumes such as sainfoin (Onobrychis viciifolia), bird’s-foot trefoil (Lotus corniculatus) and alfalfa (Medicago sativa), grown pure and in binary mixtures with cocksfoot and on damage caused by root pests of Sitona spp. and Otiorrhynchus ligustici. It was found that the productivities of aboveground and root biomasses in binary mixtures were significantly higher compared to the corresponding legume monocultures on average by 30.7 and 39.7% respectively in mixtures with sainfoin, by 15.0 and 73.1% in mixtures with bird’s-foot trefoil, and by 18.7 and 49.6% in mixtures with alfalfa. The weight of dry aboveground biomass in the pure leguminous crops slightly exceeded that of the corresponding leguminous components in the mixtures, whereas the productivity of cereal plants in mixed crops was significantly lower compared to the pure cocksfoot on average by 38.5, 47.0 and 51.7% in mixtures of sainfoin, bird’s-foot trefoil and alfalfa respectively. A similar tendency was observed with regard to dry root biomass. Damage to nodules by Sitona larvae in mixtures decreased significantly: on average by 33.5% (sainfoin + cocksfoot), by 50.3% (bird’s-foot trefoil + cocksfoot) and by 55.6% (alfalfa + cocksfoot) compared to pure grown legumes. The damage caused by Otiorrhynchus ligustici, as expressed by the length of gnawed furrows, in the mixtures with sainfoin, bird’s-foot trefoil and alfalfa decreased considerably - by 12.5, 77.8 and 59.5%, respectively - compared to the pure crops. The damage caused by the аlfalfa snout beetle had the most significant negative effect on aboveground and root biomass productivities. Mixed cultivation systems of forage crops are an economically and ecologically sustainable method of insect pest control.

The distinctive structure of the adult male hypopygium, bearing a thickset digitus and a stout elongated superior volsella, is presented. Intraspecific morphological variations are described in order to compare C. crassus and C. nigrovittatus (Goetghebuer, 1922), treated as close relatives. The geographical distribution and ecology of the two species are commented on.

Abstract Although research into alien species usually focuses on their negative aspects associated with their penetration into native ecosystems, their influence is much more complicated. This study investigated the pollinators of Bryonia dioica, an invasive climber in the temperate zone. Flowers of this plant in two cities in western Poland (Bydgoszcz and Poznań) were visited by 27 bee species, the most frequent ones being Apis mellifera and Andrena florea. Until recently, the latter was regarded as rare and threatened in Poland. Our results indicate that the spread of Bryonia dioica into urban areas has enabled large and stable populations of Andrena florea to flourish there. This study investigated the daily and seasonal dynamics of its activity. A positive relationship was found between the spread of Bryonia dioica and the presence of its obligatory pollinator Andrena florea. Alien plant species are thus not only an additional source of food for local pollinators but also may favour the occurrence of otherwise rare species with specific food requirements, such as A. florea.

Abstract Stored grains are threatened by several insects, leading to losses in quality and quantity. Several studies have revealed the risks of using chemicals that can cause serious health problems for humans. It is in this perspective that the objective of our work should be seen: It was to assess the effect of the essential oil and leaf powder of Mentha pulegium against Sitophilus oryzae and Tribolium castaneum adults attacking post-harvest cereals. The insecticidal activity of the essential oil against these two insects was evaluated by three methods: contact, inhalation and ingestion. The ingestion method was used in the case of the leaf powder. The essential oil and leaf powder of Mentha pulegium exhibited insecticidal activity against Sitophilus oryzae and Tribolium castaneum adults (Mentha pulegium essential oil caused up to 100% mortality of both insects). Both insects were influenced affected by the dose, exposure time and the method by which the insecticidal activity of the essential oil was demonstrated. Adults of Sitophilus oryzae were more sensitive to different concentrations of essential oil and leaf powder than those of Tribolium castaneum. The essential oil has no effect on the germination rate of soft wheat grains (Triticum aestivum). On the contrary, it acts positively by reducing the damage caused by these major stock pests. The data from this study could present an alternative solution for replacing synthetic insecticides for the protection of stored commodities.

The efficacy of five insecticides containing a.i. bifenthrin, dimethoate, spinosad, spinetoram and chlorfenapyr was evaluated following RCBD against Thrips tabaci in farmer’s field for two consecutive years. The data were recorded before and after 24 h, 48 h, 72 h and 7 days of spraying. The results showed that all the insecticides reduced thrips populations compared to controls. However, the maximum reduction in thrips population and highest onion bulb yield (34.07 t/ha) was obtained with dimethoate 40EC followed by bifenthrin 10EC (33.14 t/ha). The minimum onion bulb yield (25.71 t/ha) was obtained in the control, where no insecticide was applied against thrips. If onion thrips are not controlled, the damage they cause can reduce bulb yields by 9-25%. The highest incremental return over the control (Rs.83, 600/ha), net income (Rs.82, 913/ha) and maximum cost benefit ratio were also obtained in the treatment with dimethoate 40EC.
