The sterile insect technique (SIT) has been successfully used since the 1950s as part of an integrated pest management approach in large-scale programmes to prevent, contain, suppress and eradicate key insect pests in many countries throughout the world. During this period, over one trillion live sterile insects have been shipped across borders. The very few adverse incidents from this significant trade were managed and resulted in no significant impacts. The phytosanitary and zoosanitary requirements by importing countries have been simple, facilitating the transboundary shipment of sterile insects, which is carried out mostly under the framework of cooperative agreements between the governments of the countries involved, and under technical cooperation projects of the United Nations. However, the shipment of sterile insects from sources outside this governmental framework, including public-private facilities, has been complicated, despite the availability of harmonised international guidelines in some cases, such as those for fruit flies. The SIT has great potential for the control of endemic pests or against the growing threat of invasive pests that can affect whole regions and even continents. Since SIT is species-specific, with negligible risk of introducing unwanted invasive species to the environment, and with the advantage of reducing insecticide use, a harmonised framework that recognises the low risk of SIT would facilitate shipments of sterile insects across borders and help to expand the use of this effective and environmentally friendly technology. The scope of this paper is limited to insects that have been sterilised using ionising radiation.

There are significant numbers of transboundary shipments of live insects for pollination, pest management, industrial processes, research and other uses, but data collection and analysis have proved difficult. The World Organisation for Animal Health and Collectif TIS (Technique de l'Insecte Stérile), a French think tank, carried out a stakeholder survey to understand the nature of the live insect trade and potential challenges to safety and efficiency. Target respondents had experience in the areas of biocontrol, sterile insect technique, entomological research and regulatory affairs. Although the survey was sent globally, the responses were unintentionally biased towards Europe, where interest is high, since this region is developing a comprehensive framework to promote the use of beneficial insects to replace pesticides. The survey also explored respondents' knowledge of several international agreements on the movement and risk management of beneficial or invasive insects. Knowledge of the various regulations was generally poor, and respondents highlighted a perceived lack of clarity regarding live insect shipments in the existing international regulations and guidelines. Almost two-thirds of participants reported reluctance by carriers to accept live insects for shipment, and three-quarters described occasional to systematic delays that resulted in a reduction of quality or viability. Some respondents reported that they instead hand-carry live insects, mostly in small quantities. Participants described being directly involved in trade covering 70 species of live insects and ticks transported among 37 countries, with volumes ranging from fewer than ten insects to over a million per shipment. Of these, 30% were potential vectors of pathogens to humans or animals, 42% were potential plant pest species (including some used for biocontrol), and 17% were classical biocontrol agents. The results of this survey begin to define the current scope, scale and issues for those involved in shipping live insects and ticks across political boundaries. The survey's aim is to persuade regulatory bodies and shipping operators to facilitate safety, efficiency and consistency in this underdeveloped sector.

The World Organisation for Animal Health (WOAH, founded as OIE) is the recognised intergovernmental standard-setting organisation for animal health and welfare. The WOAH mandate is to support its members in the prevention of the spread of animal diseases of concern, as listed in the Terrestrial Animal Health Code (Terrestrial Code). Once a disease, infection or infestation is listed, national Veterinary Authorities have the obligation regularly to notify WOAH of the presence or absence of the listed disease. In regard to insects, the scope of the Terrestrial Code limits its recommendations to preserving the health of bees (species of the genus Apis, extended to the genus Bombus and to the stingless bees for one disease). However, it does not include standards to mitigate the potential animal health risks associated with the international trade of other insects. A description of the standard-setting process and a review of the history of the standards for bee health highlight the resources and requirements to expand the scope of the Terrestrial Code to include recommendations for animal health risk mitigation measures for the safety of international trade in insects. Any initiative to develop guidance on insect trade should include WOAH in its role as the sole global standard-setting organisation on animal health and welfare matters. This aligns with the WOAH commitment to a One Health approach.

This paper provides a concise summary of the guidelines and regulations that govern the shipment of insects and related arthropods into and out of India. It discusses the Plant Quarantine (Regulation of Import into India) Order, 2003, which regulates the import of agents for biological control, and the Biological Diversity Act, 2002, and associated Biological Diversity Rules, 2004, which guide the transfer of insects and related arthropods for identification, taxonomic research, and commercial purposes. Insect trade for some food and feed purposes is also mentioned. Finally, some implications, conclusions and recommendations are presented.

Japan imports a wide range of arthropods for industrial use and as companion animals. Such imports may threaten ecosystems locally and in their regions of origin. Two iconic insect imports that pose ecological problems are agricultural bumblebees and companion beetles. Colonies of the bumblebee Bombus terrestris have contributed significantly to agricultural production since they were first brought to Japan in the 1990s. But, in their progressive feralisation, they harm populations of native bumblebees through competition, hybridisation, and the introduction of parasites. They also threaten native plant reproduction. The species is currently permitted for agricultural use only in netted greenhouses. Since 2000, imports of companion beetles have thrived, with an estimated market size of many billions of yen. The popularity of rare species has led to a sharp rise in prices, overhunting, and smuggling from their native countries. These exotic species may also become invasive if they escape into nature. There are no clear restrictions on beetle imports, but a government campaign is aimed to improve ethical standards for breeding. In addition, imported tarantulas, centipedes and scorpions are becoming increasingly popular. These species pose similar threats as imported beetles and bees, but the actual state of importation and breeding is difficult to ascertain. Importing insects into Japan can create the following issues: the overexploitation of rare species collected from their native habitats; the traffic in species of which collection and sale is prohibited; the risk that escaped individuals will breed as invasive species; and the introduction of alien microorganisms and parasites.

A network of scientists involved in shipment of live insects has met and generated a series of articles on issues related to live insect transport. The network is diverse, covering large-scale commercial interests, government operated areawide control programmes, biomedical research and many smaller applications, in research, education and private uses. Many insect species have a record of safe transport, pose minimal risks and are shipped frequently between countries. The routine shipments of the most frequently used insect model organism for biomedical research, Drosophila melanogaster, is an example. Successful large scale shipments from commercial biocontrol and pollinator suppliers also demonstrate precedents for low-risk shipment categories, delivered in large volumes to high quality standards. Decision makers need access to more information (publications or official papers) that details actual risks from the insects themselves or their possible contaminants, and should propose proportionate levels of management. There may be harm to source environments when insects are collected directly from the wild, and there may be harm to receiving environments. Several risk frameworks include insects and various international coordinating bodies, with experience of guidance on relevant risks, exist. All stakeholders would benefit from an integrated overview of guidance for insect shipping, with reference to types of risk and categories of magnitude, without trying for a single approach requiring universal agreement. Proposals for managing uncertainty and lack of data for smaller or infrequent shipments, for example, must not disrupt trade in large volumes of live insects, which are already supporting strategic objectives in several sectors.

The majority of worldwide trading in live arthropods is done by specialised companies that produce and distribute beneficial insects, mites and nematodes for augmentative biological control of pests on crops. These beneficial arthropods, predators or parasitoids of crop pests and some nuisance species, which are harmless to humans, plants and other animals, are mass-reared, transported and released in the target environment as a viable alternative to chemical pesticides. As such, they play a major role in achieving a more sustainable and regenerative agriculture. Thousands of international air shipments are performed yearly by up to 30 major companies. Over the decades that this industry has been active, no significant transport problems have arisen. This is due to stringent standards that the industry has generated, including designated departments to deal with quality control and logistics, as well as guides for each species concerning packaging, storage and transport conditions. In addition, transporters always adhere to the regulatory standards of the importing and exporting countries, which is attested to by the documents included by the companies with each shipment. Two major issues arise when shipping live arthropods: first, the need to maintain stable environmental conditions within the shipping units (maintaining a cool chain) and, second, minimising transport time (preventing delays). This paper discusses the procedures implemented by the companies to assure quality, the documents required and provided currently, and the challenges to the safe transportation of beneficial organisms.

The logistics of shipping live invertebrates should be straightforward: it requires timely delivery and packaging that ensures survival and confinement. The packaging is the responsibility of the shipper, whose interest is to maintain the product's quality during shipment and to ensure that no specimens escape. Timely delivery relies on the ability of the shipping agent to organise an efficient route of transport and carriers to fulfil their function effectively. This article explores this underserviced sector. While similar logistics capacity exists for other goods that require fast delivery (such as vaccines and fresh food), stakeholders who require live invertebrate shipping often have difficulties in finding transporters able or willing to handle such services. The authors bring examples from biocontrol, showing the current complexity and inconsistency of logistics. For some countries and stakeholders, this issue can be a significant barrier to the growth of a sustainable biocontrol sector. The authors also explore misconceptions (about packaging, liability and paperwork) and unclear rules (such as requiring generic veterinary certificates that are rarely relevant for invertebrates) that may cause express courier companies to refuse carrying live invertebrates. These issues often result in packages not being handled as a priority during transport connections or customs clearance, and significant delivery delays. The authors propose improvements that could streamline transport through changes that fit within existing shipping processes. This article is furthermore intended as a call to transport and inspection stakeholders to use the existing guidance and other resources to support this underdeveloped sector more effectively.

The globalisation of trade is opening the way to the spread of species in new regions where they may cause negative impacts. Invasive mosquito species such as Aedes aegypti and Aedes albopictus are raising concern for their capacity to transmit several arboviruses of public health and veterinary importance. Currently available integrated vector management measures do not achieve satisfactory results when deployed against these urban mosquitoes. Moreover, insecticides are losing their effectiveness owing to the resistance developed by the target species. Policies regulating the use of insecticides are progressively restricting their market availability and this trend is expected to continue. Genetic control methods, such as the sterile insect technique (SIT), based on the use of irradiation to sterilise male mosquitoes, are showing good efficacy in pilot trials at local scales in some Aedes albopictus-colonised urban areas in Europe, without any negative effects. The main limitation is the cost, which may be significantly reduced through the introduction of automation in the mass rearing and drone technology in the field release. These technological advancements require substantial investments at a scale that can only be achieved with centralised production and extensive distribution, which in turn may be granted only if the authorisation frameworks, including the regulation of international transportation and aerial release in an urban setting, are clarified and matured.
