“…Enclosed environments such as greenhouses and glasshouses, which restrict immigration and escape from insecticide exposure under climatic regimes favouring rapid and uninterrupted population growth, are widely recognized as providing near-ideal conditions for selecting resistance genes (see, for example, Parrella 1987; Sanderson & Roush 1995;Denholm et al 1998). In the case of B. tabaci and other species that transmit plant viruses or cause cosmetic damage to high-value ornamental or edible produce, these problems are accentuated by very low or even zero pest tolerance thresholds that promote frequent spraying and hence intensify selection pressures.…”

“…The basic dilemma is that these are often the species whose biology also renders them most abundant and damaging, and therefore primary targets of insecticide treatments. For this reason, they may also be ones in which resistance is already well advanced, diminishing the supply of e¡ective compounds and placing new insecticides under severe threat of overuse and hence resistance from the outset Denholm et al 1998).…”

For many key agricultural pests, successful management of insecticide resistance depends not only on modifying the way that insecticides are deployed, but also on reducing the total number of treatments applied. Both approaches bene¢t from a knowledge of the biological characteristics of pests that promote or may retard the development of resistance. For the white£y Bemisia tabaci (Gennadius), these factors include a haplodiploid breeding system that encourages the rapid selection and ¢xation of resistance genes, its breeding cycle on a succession of treated or untreated hosts, and its occurrence on and dispersal from high-value crops in greenhouses and glasshouses. These factors, in conjunction with often intensive insecticide use, have led to severe and widespread resistance that now a¡ects several novel as well as conventional control agents. Resistance-management strategies implemented on cotton in Israel, and subsequently in southwestern USA, have nonetheless so far succeeded in arresting the resistance treadmill in B. tabaci through a combination of increased chemical diversity, voluntary or mandatory restrictions on the use of key insecticides, and careful integration of chemical control with other pest-management options. In both countries, the most signi¢cant achievement has been a dramatic reduction in the number of insecticide treatments applied against white£ies on cotton, increasing the prospect of sustained use of existing and future insecticides.

“…The ongoing discovery and development of novel insecticide classes is vital for ensuring the sustainability of crop protection strategies. However, taking new compounds from the laboratory to the marketplace is an increasingly challenging process 1. Requirements for a large body of data relating to their efficacy, toxicity, persistence and metabolism are supplemented by the need to anticipate and counter the threat of pests rapidly acquiring resistance to new molecules.…”

Susceptibility of standard clones and European field populations of the green peach aphid, Myzus persicae, and the cotton aphid, Aphis gossypii (Hemiptera: Aphididae), to the novel anthranilic diamide insecticide cyantraniliprole

Cyantraniliprole is currently the only anthranilic diamide (IRAC MoA 28) insecticide targeting aphid species such as M. persicae and A. gossypii. There is no evidence to suggest that the performance of this compound is affected by commonly occurring mechanisms that confer resistance to other insecticide chemistries. Cyantraniliprole is therefore a valuable tool for managing insecticide resistance in these globally important pests.

“…One major limiting factor to global food production is damage by pests, during both growth and storage stages. The use of synthetic pesticides has been an effective way to control pests, but their efficacy is constantly weakened by development of resistance in economically important pests 2. Increasing interest in the application of plant secondary metabolites in insect pest management, as an alternative to the use of synthetic insecticides, has led to the search for active plant compounds, less poisonous to the environment and with low mammalian toxicity 3…”

Bioactivity of extracts and isolated compounds from Vitex polygama (Verbenaceae) and Siphoneugena densiflora (Myrtaceae) against Spodoptera frugiperda (Lepidoptera: Noctuidae)

The effects of crude extracts, fractions and isolated compounds from Vitex polygama Cham. and Siphoneugena densiflora Berg were evaluated on the development of Spodoptera frugiperda JE Smith, a destructive insect pest of corn and several other crops. The extracts and fractions were incorporated into an artificial diet at 1 mg g(-1) and offered to the insect during its larval stage. Length and viability of larval and pupal stages as well as pupal weight were assessed. Isolated compounds were tested through superficial contamination of the diet at 0.1 mg g(-1). Weight and viability of ten-day-old larvae were determined. Methanolic and hydroalcoholic S. densiflora extracts caused 100% larval mortality, while leaf and fruit hydroalcoholic extracts from V. polygama were the most active. Among the isolated compounds, flavonoids presented the best insecticidal results, and tannins the best larval growth inhibition.
