Antagonistic interactions between the nymphal parasitoid, Tamarixia radiata Waterston (Hymenoptera: Eulophidae), and the ARSEF 3581 strain of the entomopathogenic fungus, Isaria fumosorosea Wize (Hypocreales: Cordycipitaceae), could disrupt biological control of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae). Three interactions were evaluated under laboratory conditio...
Diverse insect species harbor symbiotic bacteria, which play important roles such as provisioning nutrients and providing defense against natural enemies [1-6]. Whereas nutritional symbioses are often indispensable for both partners, defensive symbioses tend to be of a facultative nature [1-12]. The Asian citrus psyllid Diaphorina citri is a notorious agricultural pest that transmits Liberibact...
The vine mealybug (VM), Planococcus ficus (Signoret), is an Afrotropical species, whose worldwide populations probably originated from the Mediterranean basin. It was introduced to the Americas during the second half of the 20th century (Ben-Dov 1994; Gill 1994). Until the early 1980s, this pest was frequently misidentified as the citrus mealybug, Planococcus citri (Risso), as both Planoccocus ...
strains of spiroplasma citri have been classified into five groups based on electrophoretic mobility (em) of spiralin protein and rflp analysis of spiralin gene (foissac et al. 1996). in the present study, two isolates of s. citri qualifying for formation of a sixth group are reported. infection of sesame plants by s. citri has been reported previously (salehi and izadpanah 2002). samples of ve...
The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is the major pest worldwide because it can transmit bacteria associated with greening disease (huanglongbing, HLB). most common management strategy of this chemical control, but often results in resistance and threatens sustainability culture. There therefore need for sustainable control strategies such as biological co...
TheAsiancitruspsyllid,Diaphorina citriKuwayama, is aworldwidepest of citrus,which vectors the putative causal pathogen of huanglongbing. Current management practices warrant continuous monitoring of Þeld populations for insecticide resistance. Baseline activities of acetylcholinesterase (AChE), general esterase, and glutathione S-transferase as well as sensitivity of AChE to selected organophos...
