The Asian citrus psyllid, Diaphorina citri Kuwayama (Homoptera: Psyllidae) is a pest of citrus and close relatives of citrus. Asian citrus psyllid damages plants directly through its feeding activities. New shoot growth that is heavily infested by psyllids does not expand and develop normally and is more susceptible to breaking off.

A fungal pathogen that killed adult Diaphorina citri Kuwayama (Asian citrus psyllid) in Florida citrus groves was isolated, characterized molecularly and morphologically and identified as a novel isolate of Isaria fumosorosea (Ifr) (= Paecilomyces fumosoroseus) from the Asian citrus psyllid (Ifr AsCP), but no concentration-mortality or time-response data were obtained.

The index of prices received by fruit and tree nut growers averaged 144 (1990-92=100) the first 2 months of 2011, 2 percent below the same time in 2010. This decline reflects the lower price index in February. Growers received lower prices this February for most domestically produced fruit in the market this winter, except for fresh pears.

Market, Certification and Production Information for Producers and International Trading Companies

For some people organic agriculture is “farming without chemical fertilizers and pesticides”. This is short and concise, but misses important characteristics. Organic agriculture follows the logic of a living organism in which all elements (soil, plants, farm animals, insects, the farmer etc.) are closely linked with one other. Organic farming therefore must be based on a thorough understanding and clever management of these interactions and processes.

Your rating: None

The Asian citrus psyllid, Diaphorina citri Kuwayama, was discovered in Florida in 1998. It can be one of the most serious pests of citrus if the pathogens that cause citrus greening disease (huanglongbing) are present. Citrus greening recently has been reported in Brazil by Fundecitrus, Brazil. The establishment of D. citri in Florida increases the possibility that the disease may become established.
