As a citrus pest, Toxoptera sp. is classified as the main pest because the impact of the attack causes losses to the quantity and quality of the yield. Alternative pest control within insecticides in addition to using a knapsack sprayer or power sprayer is using Bark Pesticide Applicator (BPA), which is a tool to apply systemic pesticides through citrus stems optimally and serves to improve the efficiency of controlling main pests, safe for natural enemies, and environmentally friendly. The study was conducted at the Experimental Farm of the Indonesian Citrus and Subtropical Fruits Research Institute, Batu City, East Java, Indonesia from January to May 2018. This study compared the effectiveness of pesticide application devices using BPA and Power Sprayer (PS). The treatment was arranged using a randomized block design and repeated ten times. The test results showed that the application of pesticides with BPA was able to control aphids up to 93.84 % while PS was only able to suppress 29.48 %. Whiles the existence of natural enemies can be saved if the application of pesticides is carried out using BPA

EFSA was asked by the European Commission to consider synthetic biology developments for agri‐food use in the near future and to determine if the use of this technology is expected to constitute potential risks and hazards for the environment. Moreover, EFSA was requested to evaluate the adequacy of existing guidelines for risk assessment and if updated guidance is needed. The scope of this Opinion covers viable synthetic biology microorganisms (SynBioMs) expected to be deliberately released into the environment. The evaluation was based on: (i) horizon scanning of published information, (ii) gap analysis of existing guidelines covering the scope of this mandate, and (iii) future outlooks. A horizon scan showed that SynBioM applications could be ready for deliberate release into the environment of the EU in the next decade. However, extensively engineered SynBioMs are only expected in the wider future. For the microbial characterisation and the environmental risk assessment, the existing EFSA Guidances are useful as a basis. The extent to which existing Guidances can be used depends on the familiarity of the SynBioM with non‐modified organisms. Among the recommendations for updated Guidance, the range of uses of products to be assessed covering all agri‐food uses and taking into account all types of microorganisms, their relevant exposure routes and receiving environments. It is suggested that new EFSA Guidances address all ‘specific areas of risk’ as per Directive 2001/18/ EC . No novel environmental hazards are expected for current and near future SynBioMs. However, the efficacy by which the SynBioMs interact with the environment may differ. This could lead to increased exposure and risk. Novel hazards connected with the development of xenobionts may be expected in the wider future.

Citrus are affected by many viruses and viroids, some globally widespread and some restricted to particular countries or areas. In this study, we simulated the use of high throughput sequencing (HTS) and the bioinformatic analysis of small interfering RNAs (siRNA) as a pre-screening method to guide bioindexing and molecular detection to enhance the surveillance survey of some key or emerging citrus viruses, such as non-European citrus tristeza virus isolates (non-EU CTV), citrus tatter leaf virus, citrus leprosis virus, citrus yellow mosaic virus, and citrus bark cracking viroid, present in the EPPO lists, and the citrus yellow vein clearing virus. The HTS’s ability to detect other citrus viroids was also evaluated. The results demonstrate that HTS provides a comprehensive phytosanitary status of citrus samples either in single and multiple infections of viruses and viroids. It also provides effective information on citrus tristeza virus mixed infections despite not being able to identify the non-EU variants of the virus. Bioindexing checks each single virus infection but does not differentiate viroids on the Etrog citron indicator and is time-consuming. Molecular assays are valuable as confirmation tests of viruses and viroids but many pairs of primers are needed for a full screening and new or non-target pathogens remain undetected . In addition, the genomes of two isolates of the citrus yellow vein clearing virus and the citrus tatter leaf virus, detected in a sample from China, are described.
