Abstract

Antifeedants Impact of Plant Essential Oil on Green Peach Aphid on Potato Crops

Highlights

  • Potato, Solanum tuberosum L., (Solanaceae) is one of the essential primary food crops worldwide

  • Intercellular pathway punctures potential drop (PD), with its three sub-phases it is related to intracellular punctures associated with the non-persistent virus

  • The mature aphids were kept on plants for 24 h, resulting in neonate nymphs with an age of 0–24 h that were used throughout the experiments

Summary

INTRODUCTION

Solanum tuberosum L., (Solanaceae) is one of the essential primary food crops worldwide It has been attacked by many insect pests, which causes economic losses. Green peach aphid Myzus persicae (Sulzer) (Homoptera: Aphididae) is the most economically important insect pest on potatoes in the West Bank. It primarily causes damage by directly feeding the plant phloem and carries over 200 viral diseases (Westwood and Stevens 2010). The current study aimed to determine the effect of the indigenous Palestinian medicinal EO on potato plant-induced defences (POX and PPO) and monitor the changes in aphid probing, feeding, and settling behaviour to evaluate the EO impact on aphids
