Clonal selection is the preferred breeding method used in potatoes (Solanum tuberosum L.). However this selection procedure is only efficient for more advanced generations and shows no good results when applied in the seedling up to the second clonal generation. This study assessed the feasibility of selection in early generations of full-sib potato families and compares the selection method among and within families with the combined selection under different selection intensities. Six experiments were conducted from the first (C1) until the third clonal generation (C3). In C1 a randomized complete block design with four replications of 25 plants was used. In the remaining generations RCB was employed with three replications of 10 plants. Genetic variances were lower between families than within families, for all traits, but the heritabilities between families were almost always larger. The expected gains from selection between and within families were superior to gains from the combined selection in any intensity of selection. The selection of families should have weaker intensity than selection among clones within families. The selection of families was more efficient when based on the average of environments. |

The Chrysopidae family comprises natural enemies of agricultural and forest pests. This work evaluated the prey consumption and development of one species, Chrysoperla externa (Neuroptera: Chrysopidae), fed with Spodoptera frugiperda (Lepidoptera: Noctuidae) or Anagasta kuehniella (Lepidoptera: Pyralidae) in laboratory conditions. Chrysoperla externa was reared with: newly laid or one-day-old S. frugiperda eggs; newly hatched, one- or two-day-old S. frugiperda larvae; or one-day-old A. kuehniella eggs. The number of prey offered varied with the development stage of C. externa. Larvae of C. externa and prey were transferred every 24 hours to fresh vials. Duration of the larval stage of C. externa was similar when fed with newly laid or one-day-old S. frugiperda eggs, newly hatched S. frugiperda larvae or A. kuehniella eggs. Larval survival of C. externa was 90.0 ± 2.5% when fed with A. kuehniella eggs and 73.3 ± 18.32% with newly hatched S. frugiperda larvae. Chrysoperla externa consumed high numbers of eggs of A. kuehniella and high weights of one-day-old eggs or newly hatched larvae of S. frugiperda or eggs of A. kuehniella. Chrysoperla externa could not be successfully reared in the laboratory on one- or two-day-old S. frugiperda larvae, but could on eggs of both preys and newly hatched S. frugiperda larvae. |
