Ovipositional behavior of the codling moth, Laspeyresia pomonella (L.), on several varieties of apples and pears grown in the Pacific Northwest was investigated during the spring/summer of 1979. Field studies showed that early in the season more eggs were laid on the Bosc variety than on several other apple and...
The seasonality, relationship of temperature and
photoperiod to growth and post-diapause development, and
overwintering behavior of codling moth, Cydia pomonella L.,
(Lepidoptera: Olethreutidae) were studied over a three year
(1986-1989) period. The developmental threshold varied from
a low of 9.66°C for the second instar to a high of 14.23°C
for...
The feasibility of managing codling moth, Cydia pomonella (L.), with mixtures
of Bacillus thuringiensis-based microbial and selected chemical insecticides was
studied under laboratory and field conditions. Joint actions (synergism, additivity and
antagonism) of these mixtures were determined for both egg and larval stages. Higher
rates of microbial control agents (MCAs),...
