“…Similar dysfunction in nitrate reductase activity in 5 μM, but not in 20 μM concentrations of MeJA, has been reported in sugarcane plants (Seema et al 2003). Pill-bugs are considered a pest in several fields worldwide, with crops of several plant species, including lettuce, as its host (Morisawa et al 2002;Ramert et al 2001). However, it was clear that both SA and MeJA, especially at lower doses evaluated, significantly diminished plant mortality caused by pill-bugs.…”

Effect of foliar salicylic acid and methyl jasmonate applications on protection against pill-bugs in lettuce plants (Lactuca sativa)

The effects were examined of plantresponse signaling compounds, salicylic acid (SA) and methyl jasmonate (MeJA), on resistance to pill-bugs (Armadillidium vulgare) attack in lettuce plants. Foliar SA and MeJA applications were made at weekly intervals from the emergence of the plant until one week before harvesting. SA and MeJA induced detectable levels of hydrogen peroxide (H 2 O 2 ) at least during 5 days post-application in these plants throughout their cultivation. On the whole, SA and MeJA in the concentrations and application scheme evaluated in this research did not significantly influence the dry and fresh weight matter of plants, or the chlorophyll and nitrate contents. In addition, both signal elicitors significantly diminished lettuce mortality due to pill-bugs, which was positively correlated with phenolics and flavonoids contents. Our results suggest that SA and MeJA, especially in low concentrations, should be further evaluated in lettuce production and priming resistance.

“…The diagnostic 1 H-and 13 C-NMR data, including two-dimensional NMR (H-H COSY and C-H COSY), mass spectra and specific rotation value enabled compound 1 to be identified as (+)-2,7(14),10-bisabolatrien-1-ol-4-one. All of the data were identical with those in the literature [8][9][10][11][12] for (1S,6R)-2,7(14),10-bisabolatrien-1-ol-4-one ( Fig. 3).…”

(1S,6R)-2,7(14),10-bisabolatrien-1-ol-4-one and (+)-7(14),10-bisaboladien-1-ol-4-one were isolated and identified from Cryptomeria japonica as antifeedants against Locusta migratoria L. which is well known as a serious pest to cereals throughout the world. These compounds strongly inhibited the feeding of L. migratoria only when they were combined, but each compound alone did not show any activity.

“…Presence of residues on the soil surface serves as a food source for isopods, which generally are considered decomposers of organic material (Rushton 1981, Rushton and Hassall 1983, Brody and Lawlor 1984, Morisawa et al 2002. Moreover, residues provide shelter and protection from extreme ßuctuations in ambient temperature and humidity (Davis 1984, Hassell andDangerÞeld 1990), which isopods are highly susceptible to (Al-Dabbagh and Block 1981, Brody and Lawlor 1984, ReÞnetti 1984.…”

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.
