“…Many insects display a positive UV phototaxis that can be exploited by optical pest management strategies (Barghini & de Medeiros, 2012; Kim et al, 2019). As we predicted, female egg parasitoids showed a preference for UV‐exposed microhabitats, matching the positive UV phototaxis found in parasitoids of aphids (Chiel et al, 2006), moth eggs (Van Atta et al, 2015), and psyllids (Kalile et al, 2022) in similar contexts (i.e., absence of hosts, small laboratory arenas). Since pentatomid stink bug hosts of Telenomus spp.…”

1. In insects and other terrestrial arthropods, foraging is guided in part by visual cues making use of optical radiation, which includes ultraviolet (UV) radiation. Manipulating UV exposure with lamps and photo-selective materials can help protect crops by disrupting related wavelength-dependent behaviours in various pests, but little is known on how this could also affect the behaviour of their natural enemies. To investigate the effects of UV-A radiation on parasitoid wasp foraging behaviours,we conducted laboratory and semi-field experiments on female Telenomus podisi and Trissolcus utahensis (Hymenoptera: Scelionidae) that parasitize stink bug egg masses.3. In small laboratory arenas, both species of egg parasitoid displayed a positive UV phototaxis, but UV exposure also reduced their daily spontaneous locomotor activity regardless of the time of day.4. In large field cages, parasitism (i.e., host discovery and exploitation) rates were mostly unaffected by UV-attenuated conditions created by UV-absorbing filters (macrohabitat level) and/or by the plant canopy (microhabitat level).5. This study indicates that UV radiation can be involved in egg parasitoid foraging behaviours without UV attenuation negatively affecting parasitism, reflecting the heterogeneity and potentially hazardous nature of this abiotic factor. 6. We highlight the importance of examining the role of UV radiation as an environmental cue in beneficial insects, especially with the prospect of combining physical and biological pest management strategies.

“…The parasitoid T. radiata is also attracted to UV LEDs so the combination control measure can be done by using this trap. The female parasitoid is equally attracted to UV during the day and at night, but males are more attracted to it at night [31]. PDS-silenced citrus (CTV-tPDS) can be used to attract D. citri through visual, olfactory and gustatory cues.…”

The global increase in human population has heightened the demand for citrus fruits and their derivatives, necessitating effective management strategies to mitigate the impact of huanglongbing (HLB) disease. Caused by gram-negative bacteria such as ‘Candidatus Liberibacter asiaticus’, ‘Candidatus Liberibacter africanus’, and ‘Candidatus Liberibacter americanus’, HLB is primarily transmitted by the insect vector Diaphorina citri. While traditional vector suppression methods using insecticides have proven ineffective, innovative approaches are required to control disease spread. This study aims to address the persistent nature of the vector and its ability to transmit HLB throughout its life cycle by emphasizing trapping and repellent techniques. By implementing early detection methods, utilizing disease-resistant citrus varieties, employing disease-free seeds, enhancing nutritional regimes, and reducing vector populations, promising results have been achieved in reducing vector populations and limiting HLB inoculum. The implications of this research underscore the importance of adopting trapping and repellent strategies, alongside the use of disease-free citrus plants, to effectively manage HLB and safeguard citrus plantations worldwide.

“…Two biological control agents have been identified for D. citri, both parasitic wasps (Tamarixia radiata and Diphorencyrtus aligarhensis) (Hall, 2008). T. radiata was released and successfully established in the USA but parasitism rates have been variable, particularly where ants protect the psyllids.…”

Scope This Standard describes procedures for official control with the aim of detecting, containing and eradicating those ‘Candidatus Liberibacter’ species which are causal agents of Huanglongbing (also known as citrus greening disease) and their vectors Trioza erytreae and Diaphorina citri. NPPOs may draw on this guidance when developing national contingency plans for outbreaks of ‘Candidatus Liberibacter’ species and their vectors. Approval and amendment First approved in 2019‐09.
