California Red Scale Males are Already Flying!
Once again, we are having hot dry weather conditions in the San Joaquin Valley. This means that the first male California red scale are already flying in Kern and Tulare counties (Biofix) and degree days are accumulating 1-2 weeks ahead of 'normal'. Unless we get cooling weather, this means that the first generation of crawlers will be emerging earlier than usual. See degree day calculations for Kern and Tulare counties.
