Flies not automatically deterred from fruit by prior oviposition

An often repeated statement in the Bactrocera literature is that females won’t oviposit into fruit if that fruit is already infested with larvae.  A new paper led by ARC ITTC postdoc Dr Rehan Silva shows that this is only partially correct.  Females may use infested fruit if they have prior oviposition experience on that fruit type, and…

New parasitoid paper

The most recent paper from Kiran Mahat’s thesis has appeared in Biocontrol Science and Technology.   The paper shows that parasitoids held in the presence of host fruit flies mature eggs faster than wasps held on their own.  However, the species of fruit fly is important and must be a host of the wasp: non-host fruit flies do not…
