Although genetically modified (GM) plants expressing toxins from Bacillus thuringiensis (Bt) protect agricultural crops against lepidopteran and coleopteran pests, field-evolved resistance to Bt toxins has been reported for populations of several lepidopteran species. Moreover, some important agricultural pests, like phloem-feeding insects, are not susceptible to Bt crops. Complementary pest co...

the search for alternative ways of controlling sericultural pests has led to the investigation of plant sources for naturally occurring compounds which may have insect growth regulatory, feeding deterrency, repellency and confusantcy characteristics. more than 2000 species of the families asteraceae, fabaceae and euphorbiaceae are known that possess some insecticidal activity. plants with insec...

Invasive alien plants can pose serious threats to cultivated and wild plants. This provides the basis to regulate them as ‘plant pests’ within the framework of plant health. To assess if a regulation would be appropriate, necessary and effective, and to identify available options for measures to reduce a possible risk, the revised International Standard on Phytosanitary Measures No. 11, “Pest r...

When plants are damaged, they produce semiochemicals which can act as repellents for herbivorous pests and as attractants for organisms antagonistic to these pests, e.g., predators and parasitic wasps. Plants can also produce signals that warn other plants of impending attack. From this range of phenomena, it is possible to identify new ways to control pests. Although, in the past, we have need...

BACKGROUND The solanaceous fruit crop pepino (Solanum muricatum Ait.), originating in the Andes, is grown commercially in South American countries and New Zealand. In these areas, pests and diseases of pepino have been identified well; however, to date, these have seldom been investigated in detail in Japan. Herein, we attempt to reconstruct an agricultural production system for commercial pepi...

Insect pests have caused noticeable economic losses in agriculture, and the heavy use of insecticide to control pests not only brings the threats of insecticide resistance but also causes the great pollution to foods and the environment. Transgenic plants producing double-stranded RNA (dsRNA) directed against insect genes have been is currently developed for protection against insect pests. In ...

Lepidopteran stemborers and parasitic weeds in the genus Striga are major constraints to efficient production of cereals, the most important staple food crops in Africa. Smallholder farmers are resource constrained and unable to afford expensive chemicals for crop protection. Development of a push-pull approach for integrated pest and weed management is reviewed here. Appropriate plants were di...

In an age of free international shipments of mail-ordered seeds and plants, more policing will not stop the global migration of hitchhiking pests. The solution is in a preemptive response based on an internationally coordinated genomic deployment of global biodiversity in the largest breeding project since the "Garden of Eden." This plan will enrich the narrow genetic basis of annual and perenn...

Genetically modified (GM) crops are used extensively worldwide to control diploid agricultural insect pests that reproduce sexually. However, future GM crops will likely soon target haplodiploid and parthenogenetic insects. As rapid pest adaptation could compromise these novel crops, strategies to manage resistance in haplodiploid and parthenogenetic pests are urgently needed. Here, we develope...
