Effects of the fungus Isaria fumosorosea (Hypocreales: Cordycipitaceae) on reduced feeding and mortality of the Asian citrus psyllid
, Diaphorina citri (Hemiptera: Psyllidae).
To date, the psyllid
has reached 15 counties throughout Southern California; however, HLB has only been recorded in one tree in California -- a lemon/pummelo tree found on residential property in the Hacienda Heights neighborhood of Los Angeles in 2012.
In addition to expediting such efforts, information from Cooper's psyllid
dissections may eventually set the stage for targeting Liberibacter directly.
The bacteria, which is transmitted through the citrus psyllid
insect, has already destroyed a large quantity of trees, mainly in the aforementioned town, where about 800 acres are dedicated to citrus crops including oranges, mandarins, grapefruits and limes, the farmers said in a statement.
The Asian citrus psyllid
(ACP; Diaphorina citri; Figures 1 and 2) is an important invasive pest of citrus in the Americas because it transmits phloem-limited bacteria that are putatively responsible for citrus greening disease (Bove, 2006).
The tree ailment, called Huanglongbing, citrus greening or yellow dragon disease, is usually spread by the Asian citrus psyllid
, a tiny, aphid-like winged insect that feeds on citrus tree leaves.
Based on observations conducted in Cameroon, we report ant attendance of the widely distributed Afrotropical psyllid
Diaphorina enderleini Klimaszewski, 1964, developing on Vernonia species.
Common pests include leafminer, mites, and psyllid
Officials are hoping the introduction of a species of psyllid
insect will act as a form of natural pest control for the knotweed.
Now the Government has given the go-ahead for the use of the psyllid
insect, a predator of the plant in Japan, to act as a natural form of pest control - the first time such a solution has been used to help control the spread of a non-native invasive plant in Europe.
The tiny psyllid
insect, Aphalara itadori, which feeds on the sap of the killer weed, will be let loose around the country.
, a potentially devastating citrus pest, has been trapped in Echo Park, officials said Wednesday.
The bug concerned is a psyllid
or jumping plant louse called Aphalara itadori.
Defra Ministers are seeking people's views on proposals to release the non-native psyllid
Aphalara itadori in Wales and England to help control Japanese knotweed (Fallopia japonica).
Researchers say the insect - it is officially a psyllid
- would potentially target only a few other closely-related non-native species of knotweed if it were released in the UK.
