A 5 - yearstudyconducted in 20 country expose that four unlike yield flies — which make incalculable damage to crop across Asia , Africa , the Pacific and part of South America — are , in fact , the same species . The discovery will not only ease patronage restrictions , but aid world-wide attempt to reduce the pestilence ’s population .
Up until now , the Oriental yield fly front ( Bactrocera dorsalis ) , the Philippine fruit fly ball ( B. philippinensis ) , the Invasive yield fly ( B. invadens ) and the Asian papaia yield fly ( B. papayae ) have been intimately impossible to discern from each other , which has made them difficult to manage , quarantine and sketch .
The ability to on the dot identify species is central to pest management , let in quarantine measures or bans apply to internationally traded fruit and veggie .
prevent alien yield flies from enter their borders has been a major worry for several countries . The cogitation ’s findings mean that trade restriction colligate to the fruit fly should now fall away in cases where the worm is present in both the importing and export country .
“ This outcome has major implications for global works biosecurity , particularly for developing countries in Africa and Asia,”saysthe study ’s lead author , Mark Schutze , from the Queensland University of Technology . “ For example , the Invasive — now Oriental — fruit fly has lay waste to African fruit production with harvest losses exceeding 80 % and has led to widespread deal restriction with refusal of shipments of products into Asia , Europe and Japan , and significant economical and social impacts on agriculture community . ”
And now that scientist know the pestilence belong to the same species — and therefore engender together — they ’ll be capable to reduce yield tent flap population through insect nascency control scheme . One proficiency involves using low doses of radiation to sterilize aggregated - bred male tent flap , which are then release into infested area . They ’ll match with females , but not produce offspring .
