Baculovirus DNA helicases are essential for replication and are determinants of host range. Helicases of Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) and Trichoplusia ni granulovirus (TnGV) differ markedly, although both viruses replicate efficiently in the cabbage looper, T. ni. To determine whether the TnGV helicase (P137) could support replication of AcMNPV in T. ni cells...

Studies were conducted in commercial apple orchards in British Columbia, Canada, to determine whether lures combining ethyl-(E,Z)-2,4-decadienoate, pear ester (PE), with either acetic acid (AA) or sex pheromone, (E,E)-8,10-dodecadien-1-ol (codlemone), might improve monitoring of codling moth, Cydia pomonella (L.), in an area-wide programme integrating sterile insect technology (SIT) and mating ...

We established more than 200 primary cell lines of Cydia pomonella (coding moth). 81 of them were selected and screened for replication of two baculoviruses (from two different subgroups): the Choristoneura murinana NPV and the Cydia pomonella GV. Although all these cell lines had been derived from the same insect species, they varied largely in their response to challenge with the NPV. Most of...

The envelope fusion protein F of Plutella xylostella granulovirus is a computational analogue of the GP64 envelope fusion protein of Autographa californica nucleopolyhedrovirus (AcMNPV). Granulovirus (GV) F proteins were thought to be unable to functionally replace GP64 in the AcMNPV pseudotyping system. In the present study the F protein of Agrotis segetum GV (AgseGV) was identified experiment...

The codling moth, Cydia pomonella L. (Lepidoptera, Tortricidae), is a major pest of apple, pear and walnut orchards worldwide. This pest is often controlled using the biologically friendly control method known as pheromone-based mating disruption. Mating disruption likely exerts selection on the sexual communication system of codling moth, as male and female moths will persist in their attempt ...

Males of two species of moths (Grapholitha molesta (Busck) and Hehothis virescens (F )) were flown in a sustained-flight tunnel in horizontal pheromone plumes The up-tunnel velocity of the moths increased with increasing height of flight and for G molesta was independent of tunnel wind velocities Use of moving ground patterns verified that the height of flight above the ground was the factor re...

Attraction of adult codling moths, Cydia pomonella (L.) (Lepidoptera: Tortricidae), to sweet baits has been well documented. However, beneficial effects of sugar feeding on moth fitness have not been demonstrated. Longevity, fecundity, and egg fertility were examined for female/male pairs of moths maintained with the following food regimens: water, sucrose water, honey water, apple juice, apple...
