Abstract Studies were conducted in apple, Malus domestica Borkhausen and pear, Pyrus communis L. (Rosales: Rosaceae), orchards to evaluate the attractiveness of grey halobutyl septa loaded with 1 (L2) and 10 (Mega) mg of codlemone, 8E, 10E-dodecadien-1-ol, 3 mg of pear ester, ethyl (E,Z)-2,4-decadienoate (DA2313), and 3 mg of pear ester plus 3 mg of codlemone (Combo) to adult codling moth, Cydi...

The idea of enhancing insecticide efficacy against phytophagous insects with feeding stimulators was proposed as early as the 1960s, and a number of insect feeding stimulators based on sugars, molasses, and cottonseed extracts, biologically active at relatively high (5% and higher) concentrations, have been advocated. Here, we show that an acidic amino acid, L-aspartate, stimulates feeding in c...

Birds active in apple orchards in south-eastern Australia can contribute positively (e.g., control crop pests) or negatively (e.g., crop damage) to crop yields. Our study is the first to identify net outcomes of these activities, using six apple orchards, varying in management intensity, in south-eastern Australia as a study system. We also conducted a predation experiment using real and artifi...

In the codling moth Cydia pomonella (Lepidoptera: Tortricidae) plant volatiles attract males and females by upwind flight and synergise the male response to the female-produced sex pheromone, indicating a close relationship between the perception of social and environmental olfactory signals. We have studied the anatomical and functional organisation of the antennal lobe (AL), the primary olfac...

Quarantine regulations require domestic sweet cherries (Prunus avium) exported to Japan to be treated to control codling moth [Cydia pomonella (Lepidoptera: Tortricidae)]. The current procedure, methyl bromide fumigation, may be discontinued because of health, safety, and environmental concerns. To examine a potential alternative method, ‘Bing’ sweet cherries were each infested with a codling m...

The codling moth, Cydia pomonella L. (Tortricidae), is a major pest of apples, potentially causing annual losses exceeding USD62 billion globally. Growers have limited options for combatting the moth. Sprays with azinphos-methyl been banned in European Union, Turkey, and USA. To be effective, Bacillus thuringiensis or Carpocapsa must ingested large quantities, fruit damaged before larvae die. M...

A major problem in the production, storage and marketing of nuts is the infestation of insect pests such as codling moth, naval orangeworm and Indian meal moth. Present and potential quarantine treatments for both domestic and international nut markets include chemical fumigation, ionizing radiation, controlled atmosphere, cold treatment, conventional hot air or water heating and dielectric hea...
