Citrus Red Mite

Citrus red mite (CRM) Panonychus citri is only a significant pest of citrus in New Zealand when the broadspectrum activity of insecticides targeting other key pests disrupts the activity of its natural enemies The longterm solution to CRM control is to eliminate the use of disruptive agrichemicals but until this happens effective miticides are needed to control CRM Two smallplot field trials were conducted in 2004 and 2005 in a lemon orchard in Kerikeri In the first trial two applications of milbemectin abamectin fenpyroximate or propargite were effective against eggs and motile life stages Oil at 1 was not as effective as milbemectin at suppressing the incidence of eggs on leaves 6 weeks after application but was more effective than a 05 rate In the second trial the Stethorus sp ladybird and Agistemus longisetus predatory mite reduced CRM populations in both unsprayed trees and trees treated with miticides

Citrus red mite (CRM) populations can reach high levels in citrus orchards after the application of broadspectrum pesticides to control other pests It is important to know which are the key biocontrol agents of CRM in New Zealand in order to minimise use of pesticides toxic to these natural enemies CRM and natural enemies were monitored in seven orchards from January 2004 to March 2005 Ladybirds Stethorus sp and Halmus chalybeus and predatory mites Agistemus longisetus Amblyseius largoensis and Phytoseiulus persimilus were observed consuming CRM Stethorus sp and A longisetus were the most abundant natural enemies found with CRM The presence of 05 live Stethorus sp per leaf and 051 A longisetus per leaf was associated with the decline of CRM populations (15 eggs and 15 juvenile/adults per leaf) to trace levels in 45 weeks The use of neonicotinoid products can disrupt the predatory activity of Stethorus sp against CRM

Laboratory Bioassays

The ladybird Stethorus sp and the predatory mite Agistemus longisetus are the most abundant natural enemies found with high populations of citrus red mite (CRM) (Panonychus citri) To enable the continued use of pesticides that may be toxic to one or both of these predators knowledge of their roles in regulating CRM populations is required In laboratory bioassays both natural enemies alone and in combination reduced the number of eggs and immature CRM However A longisetus alone did not reduce the number of CRM adults as effectively as Stethorus sp alone or in combination In a glasshouse trial predation by a combination of Stethorus sp and A longisetus reduced CRM populations faster than predation by Stethorus sp alone Stethorus sp is the more effective of the two common CRM natural enemies at reducing high populations of CRM but the combined predation of the two predators may be complementary in highly dispersed populations where there are a large number of leaves with few eggs

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
