Novel strategies for the management of soybean looper, Chrysodeixis includens (Walker) (Lepidoptera: Noctuidae), are needed due to its increasing importance, costs, and challenges in soybeans (Glycine max [L.] Merr.; Fabaceae) Americas. Pheromone-mediated mating disruption may be 1 such novel strategy, but an effective tool estimating success must found. The technique trapping male moths using ...

Cornell Cooperative Extension of Suffolk County joined with regional collaborators to monitor brown marmorated stink bug [BMSB, Halyomorpha halys (Stål)], populations in two fruit orchards using newly developed USDA # 10/20 pheromone lures. 12 traps were set near the forest borders adjacent to a 20-acre peach, a 10-acre apple orchard, and a 25-acre mixed (apple, peach, vegetable, cherries etc.)...

Mating disruption is a novel technique that has been used successfully by many apple growers for control of one or more pest species. However, this approach has not been widely adopted in some apple production regions, including Michigan. Among the factors that contribute to the relatively low adoption of mating disruption in some areas are the high cost of the technique and the presence of sev...

Olfaction is primarily mediated by highly specific olfactory receptors (ORs), a subfamily of which are the pheromone receptors that play a key role in sexual communication and can contribute to reproductive isolation. Here we cloned and identified an olfactory receptor, SlituOR3 (Genbank NO. JN835270), from Spodoptera litura, to be the candidate pheromone receptor. It exhibited male-biased expr...

Research Highlights: We investigated the negative effects of bark beetle mass trapping, especially non-target catches among target’s natural enemies. Slot traps modified with mesh screen and escape windows were tested to improve their selectiveness. Background Objectives: Two main enemies beetles, Thanasimus formicarius (L.) Temnoscheila caerulea (Olivier), are frequently trapped in high number...

I report on the attraction of the white pine cone beetle, Conophthoru.s coniperda (Schwarz) (Coleoptera: Scolytidae), to traps baited with the host monoterpene limonene in western North Carolina. Both (+)- and (-)-limonene attracted male and female cone beetles to Japanese beetle traps in an eastern white pine, Pinus strobus L., seed orchard near Murphy, NC. Catches of cone beetles were directl...

We report the identification, synthesis, and field bioassay of a novel attractant pheromone produced by males of Eburodacrys vittata (Blanchard), a South American cerambycid beetle in the subfamily Cerambycinae. Headspace volatiles from males contained a sex-specific compound, identified as 10-methyldodecanal. In a field bioassay conducted in Brazil, significant numbers of males and females wer...

The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is an important pest of field crops, fruit orchards, commercial vegetables, ornamental plants, and home vegetable gardens. Pheromone-baited traps designed to attract, trap, and kill H. halys are marketed for use in home gardens to reduce damage to plants. To test this assertion, we conducted the followi...

In managing the corn crop, European farmers frequently face presence of pest Diabrotica v. virgifera, which has a negative impact on production. Since 1992, various attempts have been made to limit its expansion and multiplication. recent years, with elimination most used chemical insecticides, had resort non-aggressive less polluting methods. Therefore, in this paper, an attempt was find solut...

The oviposition pheromone of Culex quinquefasciatus was synthesized in a racemic form in a simple (five steps), efficient, high yielding (45% total yield), and low cost way (use of relatively low cost reagents). Our synthetic racemic pheromone (SRP) was tested in the laboratory for its bioactivity on Culex pipiens biotype molestus, which is a member of the species complex that Culex quinquefasc...
