Description of key information
Helicoverpa zea were fed with Cotton plants, sprayed with Methyl salicylate. Methyl salicylate did not affect the weight gain or survivorship of neonates after a 96h feeding period but it is not possible to determine the effective concentration tested.
Key value for chemical safety assessment
Additional information
One study is available for this endpoint (Bi, J. L. et al., 1997). Initially, the aim of the study was to evaluate the effect of exogenous application of methyl salicylate on cotton resistance to H. zea. However, effects of this substance on the weight gain or survivorship of neonates H. zea after a 96h feeding period and on third-instar H. zea growth rate at both 48 and 64h feeding periods were evaluated. Thus, H. zea were fed with Cotton plants, sprayed with 100 µM Methyl salicylate in 0.1 % ethanol. Applying exogenous Methyl salicylate did not affect the weight gain or survivorship of neonates after a 96h feeding period. The effect of Methyl salicylate on third-instar H. zea growth rate was also insignificant (P>0.05) at both 48 and 64h feeding periods.
Even if this study has not been performed according to standard guideline, it provides information on the absence of toxicity at the concentration tested. As the media of exposure is plant contaminated by spray, it is not possible to determine the effective concentration tested.
Therefore, the test is waived for this endpoint.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
