To investigate fluctuation in susceptibility to insecticides in the field, natural populations of Helicoverpa armigera were collected from the same field in the region of Multan, Pakistan in 2002 and 2003. The populations were examined against pyrethroids (viz. cypermethrin, esfenvalerate and fenpropathrin) and new insecticides (viz. spinosad, abamectin and indoxacarb). In 2002, the resistance ratio (RR) of cypermethrin and esfenvalerate was significantly higher than fenpropahrin compared with susceptible population. The susceptibility to cypermethrin, esfenvalerate and fenpropathrin increased significantly in 2003; however, the RR for cypermethrin was about half the RR (38) of esfenvalerate (101) and fenpropathrin (89). The toxicity of spinosad, abamectin and indoxacarb was identical in both years. In the field experiments, abamectin was more effective than other compounds tested whereas fenpropathrin, cypermethrin and esfenvalerate had similar toxicity. These results might have important implications in resistance management and suggest that the rotational use of spinosad, abamectin and indoxacarb could help to avoid the development of multiple resistant in H. armigera.

“…Alternatively, insight could be obtained by exploring the resistance mechanisms to the insecticides. For example, Abamectin acts on the GABA receptor/ chloride ionophore complex and glutamate-gated chloride channel (Clark et al 1995;Rugg et al 2005). Any variation Fig.…”

“…Tebufenozide was first developed by Rohm and Haas Co. as an agonist of 20-hydroxyecdysone, and kills insects by initiating premature molting (Wing 1988;Wing et al 1988). Abamectin is a bacterial (Streptomyces avermitilis) based toxin that acts on the GABA receptor/ chloride ionophore complex and glutamate-gated chloride channel (Clark et al 1995;Rugg et al 2005). Resistance of DBM to Tebufenozide has been reported in laboratory selected strains, and to Abamectin in field populations (Cao and Han 2006;Qian et al 2008).…”

Changes of Sex Pheromone Communication Systems Associated with Tebufenozide and Abamectin Resistance in Diamondback Moth, Plutella xylostella (L.)

Many insect pests have evolved resistance to insecticides. Along with this evolution, the sex pheromone communication system of insects also may change, and subsequently reproductive isolation may occur between resistant and susceptible populations. In this study of the diamondback moth, we found that resistant females (especially Abamectin resistant females) produced less sex pheromone and displayed a lower level of calling behavior. Resistant males showed higher EAG responsiveness to the sex pheromone mixture of females, and responded to a broader range of ratios between the two major components compared to the responses of susceptible moths. In addition, wind tunnel experiments indicated that changes associated with insecticide resistance in the Abamectin resistant strain (Aba-R) significantly reduced female attractiveness to susceptible males. Furthermore, mating choice experiments confirmed that non-random mating occurred between the two different strains. Aba-R females with an abnormal pheromone production and blend ratio exhibited significantly lower mating percentages with males from either their own strain or other strains, which corroborates the results obtained by the wind tunnel experiments. The implications of this non-random mating for insect speciation and insecticide resistance management are discussed.

“…Some of the NPs listed above, including abamectin and spinosad, have been synthetically modified, leading to insecticides that have an altered spectrum, improved efficacy and/or improved residual. For example, synthetic modification to the 4″‐hydroxy of abamectin to form the 4″‐ N ‐methylamine yields emamectin benzoate, which possesses greatly improved efficacy for lepidopteran species . Likewise, synthetic modifications (ethoxylation of the 3′‐hydroxy on the rhamnose; reduction of the 5,6‐double bond of spinosyn J) to a mixture of spinosyns J and L results in spinetoram, a semi‐synthetic spinosyn insecticide .…”

Natural products (NPs) have long been used as pesticides and have broadly served as a source of inspiration for a great many commercial synthetic organic fungicides, herbicides and insecticides that are in the market today. In light of the continuing need for new tools to address an ever-changing array of fungal, weed and insect pests, NPs continue to be a source of models and templates for the development of new pest control agents. Interestingly, an examination of the literature suggests that NP models exist for many of the pest control agents that were discovered by other means, suggesting that, had circumstances been different, these NPs could have served as inspiration for the discovery of a great many more of today's pest control agents. Here, an attempt is made to answer questions regarding the existence of an NP model for existing classes of pesticides and what is needed for the discovery of new NPs and NP models for pest control agents.
