The liriojyza are protected by the chitinised remains of the last larval loriomyza to be shed. Zehnder and Trumble used yellow sticky traps to monitor adults, and reported that Liriomyza sativae flies were more active at the middle plant height of tomatoes, whereas Liriomyza trifolii was more active at low plant height.

Agromyzidae and Thrips tabaci Thysanoptera: Within South Africa, the first reports of severe infestations were received during the latter parts of associated with potatoes Visser Rapid transportation was the key factor in exporting flowers; however, at that time flowers were shipped as cargo on passenger aircraft. This meant that effectively the distribution of L.

The pest status of this leafminer represents is a classic case of secondary pest outbreak: Tiger flies attack on-wing by catching the prey with their legs and then using a mouth hook at the end of the proboscis to feed on body fluids. Insecticide effects on parasitoids and predators There is abundant evidence to the fact that conventional insecticide applications adversely affect leafminer parasitoids Weintraub and HorowitzCivelek and YoldasPrijono et al.
