Increasing phosphorus use efficiency in agriculture is essential for sustainable food production. Thus, the aims of this study were: i) to identify phosphorus use efficiency (PUE) in popcorn lines during the early plant stages, ii) to study the relationship between traits correlated with PUE, and iii) to analyze genetic diversity among lines. To accomplish this, 35 popcorn lines from Universidade Estadual de Maringá breeding program were studied. The experiment was conducted in a growth chamber using a nutrient solution containing two concentrations of phosphorus (P): 2.5 ?M or low P (LP) and 250 ?M or high P (HP). After 13 days in the nutrient solution, root morphology traits, shoot and root dry weight, and P content of the maize seedlings were measured. A deviance analysis showed there was a high level of genetic variability. An unweighted pair group method with arithmetic mean (UPGMA) clustering analysis identified three groups for the LP treatment (efficient, intermediate, and inefficient) and three groups for the HP treatment (responsive, moderately responsive, and unresponsive). The results of a principal component analysis and selection index were consistent with the UPGMA analysis, and lines 1, 2, 13, 17, 26, and 31 were classified as PUE. |

Factitious hosts are largely used in parasitoid production. However, changes in parasitism capacity may happen when hosts are switched. Therefore, the ability of a parasitoid species to be reared on factitious host and still keep high level of parasitism on the natural target pest after successive rearing can determine parasitoid quality and must be investigated. Thus, we evaluated Telenomus remus parasitism on Corcyra cephalonica eggs compared with its natural host, Spodoptera frugiperda eggs, for different generations. After being reared on C. cephalonica, T. remus parasitism on S. frugiperda was evaluated to measure different T. remus biological parameters and parasitism capacity (parasitoid quality). Gradual increase in C. cephalonica eggs parasitized was observed over the generations, stabilizing on generation F7. The number of parasitized C. cephalonica eggs was similar among generations (from generation F7 to F19). Taking the lifetime parasitism into consideration, parasitism capacity is similar from T. remus reared on S. frugiperda eggs from those reared on C. cephalonica eggs (generation F19). When laboratory-produced T. remus on C. cephalonica eggs was exposed to the natural host, parasitism was higher on F5 generation and stable from generations F5 to F19. Therefore,parasitoids did not lose their ability to parasitize eggs of natural host assuring good quality of the laboratory-produced parasitoid using C. cephalonica eggs as factitious host. |
