“…Boina et al [2009] found that sublethal doses of imidacloprid significantly delayed the developmental time of Diaphorina citri nymphs. IPP-10, a recently developed neonicotinoid insecticide, also delayed the development of Rhopalosip humpadi [Cui et al, 2010]. Similar results have also been found in other studies [Ruiu et al, 2006;Pineda et al, 2007].…”

“…This provides an opportunity to sample surface chemicals [Hashiba and Misawa, 1969]. Thus, aphids determine whether a plant is suitable for feeding after several probing attempts [Cui et al, 2010] observed that IPP-10 (a novel neonicotinoid insecticide) had both contact and systemic activity, with sublethal effects resulting in reduction in Rhopalo siphumpadi feeding behavior, growth rate, and fecundity. Morita et al [2007] used the EPG technique to investigate the main insecticidal mechanism of flonicamid and found that starvation is due to the inhibition of stylet penetration into plant tissues.…”

The green peach aphid, Myzus persicae Sülzer, is an important sap-sucking pest of many plants, including Chinese cabbage. The objective of the present study was to determine the effects of sublethal concentrations of two insecticides (flonicamid and thiamethoxam) and the action mechanisms on the feeding behavior of M. persicae. The median lethal concentrations (LC 50 ) of flonicamid and thiamethoxam for adult M. persicae were 2.56 and 4.02 mg/L, respectively. The sublethal concentrations of flonicamid were 0.44 mg/L (LC 10 ) and 1.25 mg/L (LC 30 ), and those of thiamethoxam were 1.19 mg/L (LC 10 ) and 2.45 mg/L (LC 30 ). The developmental period of M. persicae nymphs was 5.9 days at LC 10 and 6.1 days at LC 30 for both insecticides compared to 5.7 days for the control. Adult longevities at LC 10 and LC 30 of flonicamid were 13.2 and 13.7 days, respectively. Adult longevity at LC 10 of thiamethoxam was 14.7 days. Control adult longevity was 11.6 days. Total fecundity was higher at LC 10 (41.8 offspring/female) and LC 30 (43.0 offspring/ female) of flonicamid, and at LC 10 (42.1 offspring/female) of thiamethoxam than that of the control (29.5 offspring/female). Feeding behavior analysis using an electrical penetration graph showed that sublethal doses of flonicamid and thiamethoxam had significant effects on the duration of phloem ingestion. However, higher doses of flonicamid induced starvation by inhibition of phloem ingestion and higher doses of thiamethoxam induced contact toxicity rather than inhibition of feeding behavior. This study provides the basis for a more efficient use of these pesticides in Korea.

“…From this result it is possible to infer that there is a systemic acropetal effect (via xylem) of thiamethoxam. Cui et al (2010) showed that this active substance has good mobility via xylem. Souza et al 2006 observed that the greatest levels of the thiamethoxam insecticide in leaves were obtained 30 days after the application through irrigation water and can be found in the leaves up to 156 days of application, indicating a slow metabolism (degradation), as observed by Diez-Rodrigues et al (2006).…”

“…Thus, it was observed that the basipetal movement of thiamethoxam did not occur in a rate that would be sufficient to control the bugs. Cui et al (2010) studied the systemicity of IPP-10, which is a neonicotinoid product recently released in the market for wheat, and they observed that the product was translocated via xylem and phloem, increasing the efficiency in controlling insects.…”

During the application of pesticides on soybean fields, a vertical deposition gradient of the product can occur throughout the canopy, resulting in difficulties for controlling stink bugs that are in the middle and lower thirds of plants. This study aimed at evaluating the systemicity of thiamethoxam insecticide in different soybean phenological stages, using brown stink bugs as bioindicators of the pesticide efficacy. The study combined product application sites (lower, middle and upper third) and stink bugs infestation areas at five soybean phenological stages (R2, R3, R4, R5.2 and R6). For the R2 and R5.2 stages, plants presented acropetal translocation of the product, being the effect more evident in the R2 stage. For the R3, R4 and R6 stages, the product translocation was not sufficient for controlling the stink bugs. In all stages, for treatments with direct exposure (same infestation and spraying place), stink bugs were satisfactorily controlled.

Nicotinische Acetylcholinrezeptor‐Agonisten: ein Meilenstein für den modernen Pflanzenschutz

Die Schädigung von Nutzpflanzen durch wirbellose Schädlinge ist eine große Bedrohung vor dem Hintergrund des kontinuierlich steigenden Nahrungsbedarfs einer wachsenden Weltbevölkerung. Daher sind effiziente Pflanzenschutzmaßnahmen in der breiten Vielfalt der landwirtschaftlichen Produktion von größter Bedeutung für nachhaltige Erträge. Die Entdeckung synthetischer Agonisten, die selektiv an nicotinischen Acetylcholin‐Rezeptoren (nAChR) im Zentralnervensystem von Schadinsekten wirken und als Insektizide Verwendung finden, war ein Meilenstein in der angewandten Pflanzenschutzforschung. Diese Verbindungen läuten wegen ihrer hohen Spezifität am aktiven Zentrum und Vielseitigkeit in der Anwendung eine neue Ära der Bekämpfung einiger der weltweit schwerwiegendsten Schadinsekten ein. Diese Insektizide haben nicht nur Bedeutung als Insektenbekämpfungsmittel in der Landwirtschaft, sie haben auch unsere Kenntnisse über die Biochemie der nicotinischen Acetylcholin‐Rezeptoren von Insekten enorm erweitert. Der globale wirtschaftliche Erfolg der synthetischen nAChR‐Agonisten als Insektizide macht den nicotinischen Acetylcholin‐Rezeptor immer noch zu einem der vielversprechendsten Ziele für die Insektizidforschung.
