Project Update:Population Genomics of Natural EnemiesGSS | June 14th, 2016Kim Ferguson
Biocontrol: a brief (re-)introductionBiological control, biocontrol, natural enemies, classical vs conservation vs others...
What is biocontrol?
Types of Biocontrol
Natural
Conservation
Classical
Augmentative
Definitions based on van Lenteren, in BioControl (2012)
Agriculture & Biocontrol:Integrated Pest Management (IPM)
Che

Biological
Physical-Mechanical
Cultural
Toxic
ity Two important concepts:- Economic Injury Level (EIL)- Control, not eradication
Current events: Mosquitos and Biocontrol
What are the consequences of getting rid of mosquitos entirely?

Breeding Invertebrates for Next Generation Biocontrol
My project within BINGO
Quick recap: what is my project??• : improving natural enemies used in
biological control via next generation techniques
• RP1: Population Genomics of Natural Enemies• My own goal: population genomics of commercial vs wild
populations
• 3 species »» 3 genomes »» 3 parallel collaborations
Nesidiocoris tenuis
Used against:- Whitefly- Tuta absoluta
Nesidiocoris tenuis• Likely faces severe inbreeding pressure as well as laboratory
adaptation• Unknown source history?• Lack of stock renewal
• Work with RP10 (Valencia, Spain) in terms of how genomics can inform reducing negative effects of N. tenuis on tomato crops
• Progress: Should know by the end of the week if females in established ‘families’ laid eggs to begin sib-mating inbreeding scheme
• Upcoming: This is long-term rearing, so more rearing!
Trichogramma brassicae
Trichogramma spp.
Trichogramma brassicae
• Commercial stock is renewed from various local populations annually, so little risk of inbreeding
• Work with RP12 (Bremen, Germany) for strain-specific markers
• Progress: Obtained parthenogenetic strain from Germany, will speed up the road to sequencing as compared to inbreeding
• Upcoming: Breeding and then harvesting them for sequencing in July
Amblyseius swirskii
Amblyseius swirskii
Used against:- Whitefly (eggs & larvae)- Thrips (eggs & larvae)
Amblyseius swirskii• Likely faces severe inbreeding pressure and lab adaptation• Initial bottlenecks• Lack of stock renewal
• Work with RP3 (Valencia, Spain) in terms of how the genomic information can inform performance on tomatoes as compared to wild populations
• Progress: Scaling down industrial rearing to small-scale, isofemale rearing is proving... Difficult.
• Upcoming: Hopefully, on track for finishing inbreeding in September/October.
