Lindorus lophanthae


These are live insects and MUST be shipped OVERNIGHT. No USPS or ground shipping. 

Lindoris are tiny black coccinelid beetles that devour many types of scale. They are valuable for being able to chew through hard scale as well as eat eggs and immatures of hard and soft scale. They are used in orchards, greenhouses and interiors. With ample food, light, moisture Rhyzobius beetles will begin reproducing immediately and the next generations will take care of many scale problems. 

LIFECYCLE: The life cycle is from 35 to 60 days depending on temperature. Optimum temperature for survival and reproduction is 75° F to 80° F. The beetles do not diapause in cold temperatures or low light intensities. Adult activity has been observed at temperatures as low as 40° F. 

RELEASE INSTRUCTIONS: Once you have made it home with your Lindorus, release them immediately. Lindorus cannot be stored. Before releasing, mist the foliage of the plants in the release area. It is best to release these beetles at sundown. To release, gently shake the beetles out of their bottle in the areas most heavily infested. From 1 to 5 beetles is generally enough to colonize each scale-infested plant. From 20 to 40 beetles per large scale-infested tree has been suggested, but recommended quantities cary depending on the amount of time desired to achieve control. Winter is an excellent time to release because ant activity is reduced due to low nest temperature and interference to biological control organisms by ants is at a low point. Red scale infestations on abandoned citrus is dramatically reduced by ladybug feeding throughout the winter. 

RELEASE RATES: Note - These rates are for preventative control only, multiple releases and/or higher quantities are necessary for heavier infestations.
