Study shows disease spread in ladybirds with sexually transmitted disease
Date:2/7/2013

mating habits for example.

"What we found surprising in our study was that variation in the disease dynamics of sexually transmitted infection in ladybirds occurred at a very local level. We found differences in the prevalence of disease in a tree and bush habitat, for example that were only 100 metres apart.

"Looking at the patterns of behaviour in the population more closely we could see that those habitats with more food had higher mating rates than those that did not have such a plentiful supply, and the disease infected males and females more rapidly in these places.

"This means that the infection, which causes sterility in females, will reduce ladybird reproduction in habitats with good food supply, the very places that should be important drivers of population growth. It highlights the significance of looking very carefully at local differences in the spread of infection before predicting disease impact."
