“…The first European population was established in France in 1922. By the end of the 20th century, the pest had become a problem all over Europe, in Asia Minor, Iran, Central Asia, and western China (Jolivet 1991;Weber 2003). Its current range covers about 16 million km 2 on two continents and continues to expand (Weber 2003).…”

“…The settlers brought with them potato, Solanum tuberosum L., and started to cultivate it over considerable acreages. Unfortunately, the potato proved to be a highly suitable host plant for L. decemlineata, and the beetles quickly switched to feeding on the new and abundant host plant (Casagrande 1987;Jacques 1988;Weber 2003).…”

“…For instance, in potato genetic engineering, StRCAp could be employed to express defensive genes only in the green part of plant to specifically resist Colorado beetle (Weber, 2003), powdery mildew (Park and Jones, 2008) or aphid, which transmit several important potato viruses (Hodgson, 1991). The application of StRCAp would not only reduce the metabolic burden imposed on transgenic potato plants, but also reduce concern over food safety (Stewart et al, 2000;Shelton et al, 2002) since the edible part of potato is a tuber that grows underground.…”

ABSTRACT. Constitutive promoters have been widely used in crop biotechnology applications. Tissue-specific or inducible promoters, however, have advantages in some cases. We isolated the 731-bp 5' flanking sequence of a potato (Solanum tuberosum) gene, encoding ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) activase (RCA), which was isolated by genome walking. By using GUS as a reporter and with Northern blot analysis, the 702-bp fragment (referred to as StRCAp), ranging from nt -731 to -30 relative to the initiation code of the RCA gene, was analyzed in transgenic tobacco plants. The activity of StRCAp in leaves was 0.4-fold less than that of cauliflower mosaic virus 35S promoter, and was expressed throughout the green part of the light-grown transgenic T 1 seedlings, including cytoledons, leaves and young stems, but not roots. Further deletion analysis revealed that a shorter fragment (nt -249 to -30, StRCAp2) retained light-inducible features in cytoledons and leaves, but showed no detectable activity in young stems and roots. Although the activity of StRCAp2 in leaves was reduced significantly compared with that of StRCAp, the overall data indicated that cis-elements sufficient to regulate organ-specific and light-inducible transcription are within the 220-bp fragment. There is potential for application of StRCAp in plant genetic engineering.

“…Finally, the beetle has repeatedly been able to evolve resistance to all of the major insecticides (Alyokhin et al, 2008). As a result, the beetle is the most important global pest of potatoes and is distributed throughout the Northern Hemisphere (Weber, 2003). The ability of the beetle to rapidly evolve adaptations to novel climates may have allowed it to escape its major natural enemies.…”

Crop domestication, global human-mediated migration, and the unresolved role of geography in pest control

Ecological pest management seeks to improve pest control through the manipulation of ecological processes that promote natural enemies and suppress pests. These approaches can involve cultural practices such as reduced tillage, increased use of non-crop plants that provide food and shelter for natural enemies, and intercropping to enhance the abundance and diversity of natural enemies. A major assumption of ecological pest management is that these activities can be equally effective for all insect herbivores. Here, I propose that these strategies may only be effective for a subset of pests and geographic regions because most insect pests have complex evolutionary histories that make them difficult to manage. I discuss how crop domestication and human-mediated migration are major evolutionary events that shape the geography of interactions between plants, herbivores, and natural enemies. Insect herbivores can evolve to be pests through three major modes: 1) herbivores associated with the crop wild ancestor may shift onto the domesticated crop, 2) herbivores may host-shift from native host plants onto an introduced crop, or 3) human-mediated migration can introduce insect pests into new cropping regions. The resulting geographic structure can influence the success of pest management by altering ecological factors such as: species distributions, patterns of biodiversity, community structure, and natural enemy attack rates. I discuss how the different modes of insect pest evolution structure a set of relevant questions and approaches for ecological pest management. By acknowledging how agricultural history and geography shape the ecology and evolution of insect pests, we may collectively develop a better capacity to identify where and how ecological pest management approaches can be most broadly effective.
