“…The same results were found in the survey done in Florida on commercial orchards (Childers and Denmark 2011), suggesting that species assemblage may not be affected by the spray program implemented to control ACP.

“…Childers and Denmark (2011) surveyed seven citrus orchards receiving reduced to no pesticide from 1994 to 1996 to compare phytoseiid abundance and distribution within the tree canopy and ground cover. Dooryard trees and commercial citrus trees were also sampled from 2009 to 2014 (Childers et al 2022). However, none of these studies compared the effect of pest management programs on phytoseiid diversity and abundance.…”

The abundance and diversity of eriophyid and phytoseiid mites in south and central Florida were assessed in six citrus orchards under three different pest management systems, conventional, organic, and untreated. Tree canopy, ground cover, and leaf litter were sampled every two months in two groves each under conventional, organic, and untreated pest management from April 2019 to February 2021. The citrus rust mite, Phyllocoptruta oleivora (Ashmead) was identified from 95-99% of the samples from study groves except 45% in one untreated orchard (n = 938). The pink citrus rust mite, Aculops pelekassi (Keifer) was present in organic and untreated orchards at 5% and 28%, respectively, but absent from conventional orchards (n = 134). Twenty-nine species of phytoseiid mites were identified from 1,778 specimens. Thirteen species were present in the canopy, fifteen in the ground cover, and eighteen in the leaf litter with some common species among these habitats. In the tree canopy, Typhlodromalus peregrinus (39%), Euseius spp. (25%), and Iphiseiodes quadripilis (19%) were the dominant species.Typhlodromalus peregrinus (43%), Typhlodromips dentilis (25%), and Proprioseiopsis mexicanus (13%) were the major species in the ground cover. Species richness was lower in organic orchards (3.0) compared to conventional and untreated orchards (5.0 and 4.7, respectively). In the leaf litter, Amblyseius curiosus (26%), Proprioseiopsis carolinianus (15%), Chelaseius floridanus (14%), and A. tamatavensis (12%) were the most common species.Shannon index was significantly higher in conventional orchards (1.45) compared to organic and untreated orchards (1.02 and 1.05, respectively). Evenness was also higher in conventional orchards (0.86) compared to organic and untreated (0.72 and 0.68, respectively). Finding of several phytoseiids in abundance across pest management programs suggest the need for identifying their role in pest suppression particularly mites.

“…A recent study suggests that A. largoensis could be an effective biocontrol agent of B. yothersi in Florida (Argolo et al, 2020), where this natural enemy has been the most abundant predator in backyard and varietal citrus in multiple surveys conducted in the last decades (Childers et al, 2022). This predator is also dominant in other agricultural systems in Florida (Carrillo et al, 2010;, suggesting it must have been subject to continuous exposure to pesticides used in the region.…”

IntroductionThe flat mite Brevipalpus yothersi is the main vector of citrus leprosis in South and Central America and Mexico, where vector suppression using conventional acaricides is usually the only disease control method, leading to problems with acaricide resistance. This mite is present in Florida, where several viruses known to cause citrus leprosis were recently detected. This research builds preparedness for managing emerging viral diseases and mitigating potential problems associated with acaricide resistance by addressing the compatibility of chemical and biological control strategies against B. yothersi. The predatory mite Amblyseius largoensis has shown promise as a biological control agent of B. yothersi. However, the effects of acaricides used in citrus on this predator are unknown.MethodsThis study investigated the impact of different routes of acaricide exposure on A. largoensis, including direct contact, pesticide-contaminated prey, residual contact, and combined exposure routes in laboratory settings. Additionally, the efficacy of A. largoensis in controlling B. yothersi, alone and in combination with acaricide applications, was evaluated under greenhouse conditions.Results and discussionCommonly used acaricides like abamectin and spirodiclofen were highly effective in controlling B. yothersi and only slightly harmful to A. largoensis. Other acaricides were also effective against B. yothersi but were less compatible with the predatory mite. In the greenhouse trial, all acaricides, alone or in combination with the predators, and the predators alone, effectively suppressed B. yothersi one month after treatment application. However, B. yothersi populations significantly increased one month later in the abamectin-alone and predator-alone treatments. At the same time, the combination of abamectin and predators provided B. yothersi suppression throughout the experiment. The fenpyroximate-predator combination also provided better control than each treatment applied independently. All other acaricides provided prolonged B. yothersi control, hindering biological control probably due to the lack of prey for A. largoensis. Research findings highlight the potential for enhancing the selectivity of acaricides towards A. largoensis by manipulating their exposure route. Combining predatory mites with acaricides shows promise in improving B. yothersi management.

“…They are phloem-restricted pathogens transmitted by hemipteran insects ( Moreno et al 2021 ). Phytoplasma infections are not curable yet; consequently, prevention against them is based on either resistance breeding or vector suppression by physical barriers or chemical agents against its vector ( Paleskić et al 2017 , Childers et al 2022 ). The efficiency and success of chemical protection against the vectors highly depend on the timing, for which vector monitoring and early warning are necessary ( Perring et al 1999 ).…”

Cacopsylla pruni (Hemiptera, Psyllidae) in an apricot orchard is more attracted to white sticky traps dependent on host phenology

The colour preference of the plum psyllid, Cacopsylla pruni (Hemiptera, Psyllidae), is yet poorly studied. This species is the only known vector of the ‘Candidatus Phytoplasma prunorum’, the agent of European stone fruit yellows (ESFY), a devastating disease of several cultivated Prunus species in Europe. As ESFY is still uncurable, vector control, thus vector monitoring, is pivotal to protect these trees. Cacopsylla pruni is a univoltine, host-shelter-alternating species; overwintered adults migrate from conifer to wild or cultivated Prunus species (family Rosaceae) in late winter-early spring. To select the most effective colour indicating the arrivals of the immigrants, yellow, fluorescent yellow, white, red and transparent sticky traps were deployed in an apricot orchard in Hungary. The two most abundant species in sticky traps were C. pruni and C. melanoneura. Catches of white traps were significantly biased towards C. pruni as compared to C. melanoneura specimens. Moreover, white sticky traps were better at catching plum psyllids than the other colours. Attraction to white was strongest when immigrants from shelter plants kept arriving in the orchard, coinciding with the blooming principal phenophase of apricot trees. When the host flowering growth stage was over, catches of C. pruni in white traps declined sharply to the level of yellow traps that was highest during this post-blooming period. We recommended white sticky traps for promptly monitoring C. pruni in apricot orchards because it is more potent and more selective than yellow ones during the critically important early flowering interval.
