Pymetrozine: A Novel Insecticide Affecting Aphids and Whiteflies

Lethal effects of selected novel pesticides on immature stages of Trichogramma pretiosum (Hymenoptera: Trichogrammatidae)

“…Further, because of the selectivity of these compounds, they also may allow natural enemies to be more effective against a broad range of pests. For example, the newer insecticide flonicamid can effectively control various important homopteran species, and is compatible with T. pretiosum as noted in the this work, but is also considered harmless to other natural enemies, such as the important predators Orius laevigatus (Fieber) and Amblyseius swirskii (Athias‐Henriot) for management of thrips . Although novel products tend to be safer for natural enemies relative to older pesticides (but cf.…”

Effects of cycloxaprid, a novel cis‐nitromethylene neonicotinoid insecticide, on the feeding behaviour of Sitobion avenae

“…Pymetrozine is one of the insecticides that have systemic activity and could distribute in the plant in both acropetal and basipetal directions via the xylem and phloem system 24. A previous study proved that this compound can control sucking insects by foliar and soil application 25. Thiamethoxam, a second‐generation neonicotinoid, is considered to be a relatively polar material with good xylem mobility, and distribution to the feeding sites in plants developed a high efficacy, which is eventually suitable for seed treatment and soil application.…”

Bioassay and field‐simulator studies of the efficacy of pymetrozine against peach‐potato aphids, Myzus persicae (Hemiptera: Aphididae), possessing different mechanisms of insecticide resistance

“…It is becoming available worldwide for the control of aphids and whiteflies on a wide range of field, fruit and ornamental crops, and the control of plant‐hoppers on rice 8. 14 Its mode of action is not fully understood, but clearly differs from that of other insecticide groups. Its primary effect is to cause a rapid and irreversible cessation of feeding, due not to a deterrent effect but to a blockage of stylet penetration 15.…”
