DESCRIPTION:Plant Science Research Horizons seminar with MSc student Ryan J
 . Smith\, Live on Zoom.\n\nPesticide overuse/misuse is a major problem\, c
 ausing numerous issues\,among them inducing pesticide resistance in pest s
 pecies. Integrated Pest Management (IPM) seeks to combine different manage
 ment strategies to support sustainable agroecosystems. Biocontrol is one s
 uccessful IPM strategy. Trichogramma are popular choices for biocontrol sp
 ecies of Lepidopteran pests. They are minute parasitoid wasps that lay the
 ir eggs in Lepidopteran host eggs\, killing the host before it hatches and
  damages crops. Employing biocontrol in conjunction with chemical control 
 can be effective\, however it is essential to understand how the pesticide
 s will interact with the biocontrol species if a successful IPM program is
  to be created. This study seeks to study the effects of sublethal doses o
 f pesticide active ingredients (Spinosyn A and D) used to manage the cabba
 ge looper\, Trichoplusia ni\, a prolific pest of cruciferous crops that ha
 s evolved resistance to several pesticides. Spinosad (Spinosyn A+D)\, a fe
 rmentation product of the soil bacterium\, Saccharopolyspora spinosa\, pre
 sents an effective alternative biopesticide for T. ni management\, however
 \, Spinosad is also known to negatively impact Hymenoptera like Trichogram
 ma. The development of the parasitoid Trichogramma brassicae will be studi
 ed in T. nieggs that have been exposed to a sublethal dose of spinosad usi
 ng morphometrics and micro-CT scanning techniques. As well\, Trichogramma 
 diapause and stress-related genes will be measured to further characterize
  the effects of spinosad-treated eggs on parasitoid development and stress
