. The identification of different species of ''Delia'' can be very difficult for non-specialists as the diagnostic characteristics used for immature and/or female specimens may be inconsistent between species. Past taxonomic keys were not as comprehensive in their identification of ''Delia'' specimens; they were either too reliant on genetic characteristics, focused solely on a specific life stage, or were focused only on certain species. However current taxonomic keys aim to be more thorough by not only including morphological diagnostics for males, females, and immature specimens of various species, but also their genetic make-up or molecular barcode. Certain ''Delia'' species are of great economic importance as they are

stages, and the morphology of the larval tubercles and spiracles are used to differentiate between species. As the larvae of ''Delia'' flies attach and feed on various plant parts, each of their three larval instars have a specialized respiratory system to facilitate survival within the aqueous and acidic environment of the putrefying host plant. The third larval instar is commonly used for identification purposes of species that are of economic importance. The eggs of ''Delia'' specimens are generally white in colour and elongated ovular in shape with distinctive hatching pleats on the surface of the egg, which are unique to each species.

There are many factors that will affect the susceptibility of a plant to ''Delia'' oviposition, and subsequent larval infestation.

s found in these variety of plants in order to identify it as a suitable host. In addition to being attracted to the olfactory cues of this type of plant, visual cues such as colour, position, and visual prominence of the flowers influence which plant they will infest. In addition to the plant itself, studies with ''D. radicum'' and ''D. floralis'' have shown that other environmental factors such as soil moisture, average daily air temperature, and total precipitation can all have a positive correlation with the crop’s susceptibility to infestation.


Current pest control management


Cultural Controls


Crop Hygiene

Good crop hygiene is one cultural control used to minimize ''Delia'' infestations, particularly ''D. antiqua'' and ''D. radicum''. Studies have shown that damaged or crushed onion bulbs left behind after harvest were major sources of ''D. antiqua'' food and an

site. Damaged plants release volatile chemicals that attract gravid females while the wounds on the plants provide easy access to newly emerged larvae. As such, removing waste crop material from harvested fields is recommended to decrease overwintering populations. Cull piles of harvested onions and volunteer plants from onion fields were originally believed to also be a major source of infestation and thus must be protected against the flies. However, recent studies have observed that neither of these sites are important infestation sources as conditions within deep cull piles are unfavourable to larval survival and larvae are unable to establish on undamaged volunteer plants in the spring.


Crop Rotation

Crop rotations are often used to avoid the depletion of soil nutrients and the buildup of soil pathogens. However, crop rotation can serve to geographically distance a crop from known locations of ''Delia'' populations by planting a crop from a different plant family following the harvest of the host crop favoured by the pest. While crop rotation may be effective on certain soil- inhabiting pests that have low mobility and low dispersal capabilities, this practice is not commonly seen as a control for specialist ''Delia'' species such as ''D. radicum'' and ''D. antiqua'' since they can disperse 2000–3000 meters from the site of infestation and can have a wide host range.


Crop and Soil Covers

Covering seed beds with a physical material, such as

as it produces a high-humidity climate that is favourable to these pathogens. However, completely covering crops is not a common practice as the crop covers were found to damage crop growth, can be expensive, and are time consuming to install and remove.


Sowing, Planting, and Harvesting Times

Establishing appropriate times to sow or plant crops has multiple benefits as a cultural control. Primarily, the goal is to avoid invasion by the pest, reduce crop vulnerability to oviposition, and decrease infection from insect vectors. By sowing or planting at specific times during the growing season, plants are mature enough to tolerate low levels of attack from pests, and farmers have enough time to compensate for crops that have been damaged or destroyed. Additionally, choosing a planting time when weather conditions are unfavourable to pests or synchronized with the emergence of natural enemies of the pests can also mitigate pest populations.


Chemical Controls

s, and chlorinated hydrocarbons. However, the chemicals used were generally hazardous to the environment and thus are banned or under review and could be banned. Furthermore, in some cases, such as ''D. antiqua'' flies in the Netherlands, the pests developed a resistance to the insecticides and crops continued to be destroyed. This rise in resistance and the hazard to the environment has prompted the search for a biological control instead.


Genetic Controls


Sterile Insect Technique

The sterilization of insects in order to minimize population numbers can be accomplished either by using chemosterilants on laboratory reared males and then releasing them into the fields (
SIT Sitting is a List of human positions, basic action and resting position in which the body weight is supported primarily by the bony ischial tuberosities with the buttocks in contact with the ground or a horizontal surface such as a chair seat, ...

s on existing populations in the field. Chemosterilants used in some studies include tepa ris-(l -aziridinyl) phosphine oxidewhich is very effective at sterilizing adult flies but less so on eggs. The effectiveness of sterilization to as a genetic control against ''Delia spp.'' populations has had mixed results. One study revealed that when chemosterilants were used on exiting populations of ''D. radicum'', multiple factors, such as the tendency for females to disperse, reduction in the competitiveness of sterile males, and the failure of males to re-disperse once sterilized, all limited the population of sterility in field insects therefore not decreasing oviposition rates. Furthermore, other studies that performed SIT using chemosterilants on laboratory reared ''D. radicum'' males instead of existing populations found that they were no more effective despite releasing significantly more sterile males. Contrastingly, other studies in the Netherlands have recorded more success in sterilizing ''D. antiqua'' without lowering their competitiveness and thus were able to outcompete the wild population. However, this method requires that the sterile flies are released for at least five years before they start having a significant effect on population numbers''.'' Additionally, SIT projects on ''D. antiqua'' in Quebec have also shown a reduction in fertile adult populations, and the continuation of this technique is expected to result in a decrease in both the release rates of sterile insects and the overall cost of the program.


Biological Controls

to several species of ''Delia'' including ''D. radicum, D. floralis,'' and ''D. platura''. As Delia larvae feed on the roots of cruciferous plants and other crops, they damage the tissue which then induces the plant to emit volatile compounds. These volatiles act as chemical cues to attract predators and parasitoids of the herbivore feeding on the plant as a defensive measure. Female ''T. rapae'' are attracted to these signals and use them to identify the location of ''Delia'' larvae. Once attracted to the infested crops, ''T. rapae'' females may use antennal searching, ovipositor probing, or vibrotaxis to locate the ''Delia'' larvae buried within the plant and lay their eggs within them. ''Trybliographa rapae'' may parasitize any of the three larval instars of ''Delia''. ''Aleochara bilineata'' is a

of the ''Delia'' pupae. Female ''A''. ''bilineata'' will oviposit near the roots of the cruciferous crops, where ''Delia'' larvae are most likely to be found, and once the eggs hatch, the parasitic instars will chew an entrance hole on the vulnerable puparial wall wherein it will feed on the pupae within and undergoes two more instar stages before pupating. The emergence of ''A. bilineata'' is synchronized with the egg laying of ''Delia'' species since the first instars of ''A. bilineata'' may overwinter within the host pupae in order to emerge as adult in the warmer weather of spring. Competition occurs between ''A. bilineata'' and ''T. rapae'', which has been shown to be harmful to both specimens, but particularly ''T. rapae''. ''Aleochara bipustulata'' is another species of rove beetle that is a predator to ''Delia'' spp. however much smaller than that of ''A. bilineata''. Its life cycle is very similar to that of ''A. bilineata,'' but overall it is significantly less abundant and is currently not found in North America. As opposed to other predators, ''A. bipustulata'' favours ''D. platura'' instead of ''D. radicum'' as the puparial wall is much thinner. However, some specimens were found in smaller pupae of ''D.'' ''radicum'' and rarely found in ''D. floralis'', as these larvae are significantly larger than other ''Delia'' species. Two other parasitic wasps of ''Delia'' species were found in North America, ''Phygadeuon sp.'' and ''Aphaereta'' ''sp.,'' however, their presence were so scarce that it is suggested that they may have a more favoured host other than the root maggots.
