Effective survey methods to detect and monitor recently established, low-density infestations of emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), remain a high priority because they provide land managers and property owners with time to implement tactics to slow emerald ash borer population growth and the progression of ash mortality. We evaluated options for using gi...

The biological control agent Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is a gregarious larval endoparasitoid of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive cambium-feeding species responsible for recent, widespread mortality of ash (Fraxinus spp.) in North America. T. planipennisi is known to prefer late-instar emerald ash borer, bu...

Mating disruption and mass trapping for control of lepidopteran pests use synthetic sex pheromone to prevent males from finding and mating with females. Here, we identify the behavioral mechanism underlying mating disruption and mass trapping of American plum borer, Euzophera semifuneralis (Walker) (Lepidoptera: Pyralidae), peachtree borer, Synanthedon exitiosa Say, and lesser peachtree borer, ...

ern corn borer resistance. Few plant breeders have access to insect rearing facilities, which are necessary to Southwestern corn borer (Diatraea grandiosella Dyar) and fall maximize selection efficiency. Negative traits tend to armyworm [Spodoptera frugiperda (J.E. Smith)] damage ratings were measured on an F2-derived maize (Zea mays L.) population segregatmask genetic gains in resistance at ea...

in order to study the effects of foliar application of si (5/1000 ratio), k (2/1000 ratio) and zn (2/1000 ratio) on rice (cv. tarom hashem), an on-farm experiment carried out based on randomized complete block design with three replications in 2012. some traits such as paddy yield and yield components, neck blast disease and stem borer damage were evaluated. results showed that the effect of fo...

pod borer is one of the main factors for yield decrease of chickpea. therefore, breeding of chickpea for resistance to this pest is important. modified cry1ac gene of bacillus thuringiensis in pcry1ac-nptii plasmid containing twin t-dna for cry1ac and nptii genes have been used for transformation of chickpea. at last 38 plants had nptii gene that 36 plants of them had cry1ac gene and two plants...

The Mexican rice borer, Eoreuma loftini (Dyar), is an invasive pest of rice, Oryza sativa L., in the Gulf Coast region of the United States. This pest also damages sugarcane, Saccharum spp. hybrids; corn, Zea mays L.; and sorghum, Sorghum bicolor (L.) Moench, and feeds on weedy noncrop grasses. Multiple aspects of integrated pest management including use of pheromone traps, manipulation of plan...

Asian corn borer, Ostrinia furnacalis (Guenée), is the most destructive pest of corn in China. It causes 6 to 9 million ton yield loss in an average year. Biological control using releases of Trichogramma has increased greatly since T. dendrolimi Matsumura can be successfully mass reared on eggs of the Chinese oak silkworm, Antheraea pernyi Guérin-Méneville. The process and technique for mass p...

The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae) is endemic to Africa and is the most devastating pest of coffee worldwide. The female bores a hole in the coffee berry and deposits her eggs inside. Upon hatching, larvae feed on the seeds, thus reducing both quality and yields of the marketable product. The coffee berry borer was found in the district of Kona on ...

The first hypothesis, that argument projection is aspectually driven, finds perhaps its earliest explicit statement as Tenny’s (1987, 1992, 1994) Aspectual Interface Hypothesis and has subsequently been quite widely adopted (e.g., Arad 1998, Borer 1998). Proponents of this hypothesis often establish a connection between direct objecthood and notions such as telicity (van Hout 1996, Ritter & Ros...
