Scolytid beetles (Coleoptera: Curculionidae: Scolytinae) are a large group of beetles associated with many tree species. Some species consume dead wood and vector an array of fungi which contribute to recycling of organic material, so are often an important component of forest ecology. However, populations can increase to pest levels. In this review, we look at options for control of scolytid ...

Agriculture is the dominant sector of the economy, contributing a third of the country’s gross domestic product (GDP) and about half of Rwanda’s export earnings. The government of Rwanda has therefore made agricultural development a priority and allocated significant resources to improving productivity, expanding the livestock sector, promoting sustainable land management, and developin ...

RNA interference (RNAi), a post-transcriptional gene silencing method discovered in 1998, has been used in basic research in almost every area of biology to silence genes in order to learn about their function. This technology also has many potential applications in molecular medicine, in agriculture and many other fields. RNAi has been extensively used to understand the molecular basis of phy ...

The introduction of genetic engineering has already shown its benefits in transferring genes into crop plants and conferring resistance towards pests. Most of these crop plants on the market have been transformed with the <i>cry</i> genes from <i>Bacillus</i> species, conferring resistance towards certain insects. However, since the <i>cry</i> genes are not active against all insects, e.g. sap ...

There are more than 330 <i>Liriomyza</i> species (Diptera: Agromyzidae) and many are economically important pests of field crops, ornamentals and vegetables. Given the substantial economic losses associated with various aspects of <i>Liriomyza</i> feeding as well as the ability of these insects to rapidly develop resistance to insecticides, researchers from many countries have attempted to use ...

The world population is increasing at an alarming rate, and there is a continued need to increase crop productivity to meet the food requirements. To meet the ever-increasing demand for food, cytoplasmic male-sterility (CMS) has been successfully exploited to develop hybrids for increasing crop production worldwide. However, large-scale cultivation of crop hybrids based on a single source of C ...

In the context of possible biological control of Eurasian watermilfoil (<i>Myriophyllum spicatum</i> L.), available information is summarized on the distribution of <i>M. spicatum</i> and closely related species, and the known insect and pathogen natural enemies recorded from Eurasia. Research gaps identified include (1) lack of adequate understanding of frequency, distribution and ecological ...

Western corn rootworm (<i>Diabrotica virgifera virgifera</i> LeConte) and northern corn rootworm (<i>Diabrotica barberi</i> (Smith and Lawrence)) are major pests of maize in the USA. These pests have been managed with a variety of tactics over the last century. Both <i>Diabrotica</i> spp. have adapted to crop rotation in different ways in certain regions of the USA as well as to some of the in ...
