Plant secondary compounds deterrent but not toxic to the grass specialist acridid Locusta migratoria: Implications for the evolution of graminivory
1990
Bernays, E.A.
Six plant secondary compounds that are quite widespread in nature were shown to be deterrent to the grass specialist, Locusta migratoria. These were then tested for their post-ingestional effects over the whole of the last larval instar. To enhance the possibility of an effect, experiments were conducted where the food ration was less than half of that normally taken by insects feeding ad libitum. In no case was there any indication of a detrimental effect or any trend suggesting one. In one case (amygdalin) there was a significant increase in growth rate with the addition of the secondary compound to the diet. The evolutionary implication of these findings are discussed.
