Two greenhouse studies were conducted to examine effects of nitrogen source on primary and secondary metabolism of pac choi (Brassica rapa L. subsp. chinensis cv. Mei Qing Choi) and diamondback moth (Plutella xylostella L.) consumption, development, survival, and body weight. Applications of a liquid organic source of nitrogen (fish hydrolysate fertilizer) were compared with a conventional fertilizer to determine whether nitrogen source directly impacts pac choi chemistry (elemental composition and phenolics) and biomass and indirectly affects diamondback moth fitness parameters. There was no significant effect of fertility treatment on pac choi chemistry or biomass with the exception of percent leaf phosphorus, which was significantly higher in the conventional fertility treatment, and p-coumarin, which was significantly higher in the organic fertility treatment. Diamondback moth also affected plant chemistry. Both calcium (Ca) and magnesium (Mg) were significantly higher in plants infested with larvae compared with uninfested plants. Fertilizer affected diamondback moth fitness with percent survival and cohort development significantly reduced on pac choi associated with the organic fertilizer. However, pac choi receiving the organic treatment was similar in regard to primary nutrients and secondary compounds compared with plants that received a conventional fertilizer.

In general, Armadillidium vulgare (Latreille) are considered nonpests of soybean [Glycine max (L.) Merrill], but changes in soil conservation practices have shifted the pest status of this organism from an opportunistic to a perennial, early-season pest in parts of central Kansas. As a result, soybean producers that rotate with corn (Zea mays L.) under conservation tillage practices have resorted to removing excess corn residue by using controlled burns. In a 2-yr field study (2009-2010), we demonstrated that residue removal in burned compared with unburned plots (measured as previous crop residue weights) had minimal impact on numbers of live and dead A. vulgare, soybean seedling emergence, and isopod feeding damage over time. Specifically, removal of residue by burning did not result in higher emergence rates for soybean stands or less feeding damage by A. vulgare. In a separate study, we found that number of live A. vulgare and residue weights had no consistent relationship with seedling emergence or feeding damage. Furthermore, seedling emergence was not impacted by higher numbers ofA. vulgare in unburned plots, indicating that emergence in this study may have been influenced by factors other than A. vulgare densities. These studies demonstrate that removing residue through controlled burning did not impact seedling emergence in presence of A. vulgare and that residue and feeding damage to seedlings did not consistently relate to A. vulgare densities. Other factors that may have influenced a relationship between residue and live isopod numbers, such as variable moisture levels, are discussed.

This review includes clinical guidelines and describes legal considerations for oncology nurses to consider when they address and respond to IPV in their practice. The use of clinical guidelines that focus on IPV can provide standardized care in the oncology setting that can further help to meet the needs of these women.

Damaging populations of pillbugs (Armadillidium vulgare) occur in Kansas, resulting in reduced soybean (Glycine max) stands with few reliable control measures. Combinations of cultural and chemical controls were examined to effectively maintain soybean stands in the presence of pillbug feeding. Field studies during 2009-2010 demonstrated that a higher seeding rate (296,526 seeds/acre) compared to a lower seeding rate (148,262 seeds/acre) resulted in consistently higher plant counts (P < 0.05), which may be useful to growers trying to avoid replanting costs under significant pillbug infestations. Other than seeding rate, none of the individual and combined control measures appeared to be effective in maintaining stands across years, fields, and varying levels of pillbugs (P > 0.05). However, pillbug numbers were variable between fields, suggesting that further research is needed to examine their distribution and feeding behaviors to better understand the likelihood of damage to stands. A better understanding of this relationship will help determine if doubling seeding rates is an acceptable alternative to replanting stands.
