AbstractMixed colonies of adults of Lytta nuttalli Say and L. viridana Le Conte, and of L. cyanipennis (Le Conte) and nuttalli, and colonies containing only one of these three species have been seen in various parts of the Canadian prairies, usually in aggregations and most commonly near bodies of water. The flight period of nuttalli extends from early June to early August, of viridana from late May to late June, and of cyanipennis from mid-June to early July. The natural food plants of these three species are a variety of wild legumes, though they prefer certain cultivated legumes when present. Nuttalli and viridana will eat some non-leguminous plants, including species of Iris, Delphinium, and Brassica, and such crops as sugar beets, oats, barley, and wheat. In captivity, males and females of nuttalli and viridana mated more than once and females deposited more than one batch of eggs. Egg batches of nuttalli, viridana, and cyanipennis contained an average of 320, 340, and 390 eggs each, respectively. Cross-mating between nuttalli and viridana and nuttalli–viridana hybrids were observed in the field. Four nuttalli females were seen ovipositing in an area that contained the remains of nesting cells of leafcutter bees (Megachile sp.); these are the first recorded observations of Lytta species ovipositing in the field. The beetles preferred moist, firm soil for oviposition, and the eggs desiccated very quickly when not in contact with moisture. The eggs of these three species developed fairly uniformly at temperatures from 15° to 30 °C, and it appeared to take about 2 to 3 weeks to complete embryological development at temperatures normally encountered during June through August. Relationships among these three species suggested by their behaviour and biology are discussed.

Rate Of Increase

Life-history parameters and developmental rates of Epiphyas postvittana were determined for four natural food plants and Shorey's diet at each of six temperatures. The rate of development of larvae and the life-history parameters were influenced by both temperature and diet. The highest r(m) value was given by populations feeding on Plantago lanceolata, followed by those on Shorey's diet and Rumex crispus, all at 25 . 2 degrees C, then by Malus pumila at 19 . 9 degrees C and Trifolium repense at 25 . 2 degrees C. Zero population growth occurred at 7 . 1 and 30 . 7 degrees C. A life-table study of five geographical strains of the moth under non-variable conditions (constant temperature and artificial diet) showed that finite rate of increase (lambda) was significantly correlated with climatic features of habitats, viz. mean annual Values of temperature, rainfall and relative humidity. Peak values of lambda occurred at cooler temperatures, moderate levels of habitat moisture and high altitudes (500-1000 m); the Canberra population gave the highest value (lambda = 1 . 157), followed by Armidale (lambda = 1 . 152), Melbourne (lambda = 1 . 141), Mildura (lambda = 1 . 135) and Auckland (lambda = 1 . 118). Higher performance of E. postvittana on herbaceous plants than on woody plants suggests that it primarily evolved as a feeder on herbaceous plants.

Distribution And Ecology

The present paper reports the principal results from a survey undertaken with the objects of ascertaining the extent of the natural breeding areas of the red bollworm in South Africa and whether the habitats of the food-plants are well defined ecologically. It has been known for some years that the red bollworm feeds on wild cotton, Gossypium herbaceum, and on Cienfuegosia Hildebrandtii (Parsons), but from increased knowledge of the topography and vegetation of the country there were reasons to suppose that the distribution of these food-plants is quite considerably limited in the present and potential cotton-growing areas, and it was desirable that the situation should be investigated in some detail.

The results of the technological assessment of new apple, cherry, black currant, red currant and gooseberry cultivars of VNIISPK breeding for the suitability for the natural food production are given. As a result, the cultivars that are promising for cultivation in raw plantings have been selected. For the production of raw materials in the juice industry, apple cultivars with a high juice yield and content of soluble solids higher than 10.0% were selected: ‘Bolotovskoye’ (Vf), ‘Candil Orlovsky’ (Vf), ‘Osipovskoye’ (3x), ‘Rozhdestvenskoye’ ((Vf + 3x), ‘Zaryanka’ (Vm), ‘Priokskoye’ ((Vf + Co), etc. Based on the long-term study of cultivars for their suitability for compote, jam and jelly, the cultivars that are most suitable for these types of processing are identified. It has been found that taking into account the daily needs of vitamins C and P as the most important antioxidants, all processed products from black currant can serve as their sources, all processed products from cherries, as well as apple juice and gooseberry marmalade can serve as a source of P-active compounds. All columnar apple cultivars as well as ‘Bolotovskoye’, ‘Rozhdestvenskoye’, ‘Veteran’, ‘Imrus’, etc. show high suitability for the production of apple chips. Cherry cultivars ‘Rovesnitsa’, ‘Putinka’, ‘Podarok Uchitelyam’ and ‘Novella’ are suitable for dried fruit. Based on the long-term studies of the technological qualities of the VNIISPK gene pool, a new generation assortment has been formed that has an optimal combination of chemical and technological indicators of fruits that meet modern technological requirements and are suitable for cultivation in the raw plantations of Central Russia.
