  • Biological Pest ControlOr BPC for short

  • Biological Pest Control--BPCWhat is it?Biological Pest Control is a way of controlling pests and diseases in agriculture that relies on natural predation rather than chemicals.

  • How does it work?Biological pest control works to create a system where the insects referred to as pests and the things that cause diseases are kept at manageable levels using natural means.For example: Introducing a predator to a pest, or growing plants that keep particular insects away.

  • Let me introducethe predatorsLADYBUGSThe larva will eat more than their fare share of aphids, blackflies, caterpillars and mites. (Not really lady-like)DragonfliesThey eat mosquitoes and mosquito larva. Very important in the control of mosquito population. Parasitic WaspsThey lay their eggs IN many common pests. The eggs hatch and eat the pests alive!!

  • Here they are

  • A Wasp and its prey

  • Plants keep away the insects?How can this be?Masking/shielding the crop plants from pestsProducing smells that confuse and deter pests. Acting as trap plants by providing an alluring food that entices pests away from crops.Serving as nursery plants, providing breeding grounds for beneficial insects.

  • Did you knowBasil Repels flies and mosquitoes. Catnip Deters flea beetle. Garlic Deters Japanese beetle. Horseradish Deters potato bugs. Marigold The workhorse of pest deterrents. Discourages Mexian bean beetles, nematodes and others. Mint Deters white cabbage moth, ants. Nasturium Deters aphids, squash bugs and striped pumpkin beetles.

  • Did you know ContdPot Marigold Deters asparagus beetles, tomato worm, and general garden pests. Peppermint Repels the white cabbage butterfly. Rosemary Deters cabbage moth, bean beetles and carrot fly. Sage Deters cabbage moth and carrot fly. Southern Wood Deters cabbage moth. Summer Savory Deters bean beetles. Tansy Deters flying insects, Japanese beetles, striped cucumber beetles, squash bugs and ants. Thyme Deters cabbage worm. Wormwood Deters animals from garden.

  • Why Use BPC?Benefits:This is a very cost effective way to prevent pests. (Cheaper than pesticides).No chemicals will be used, therefore, no pollution.No chemicalsno health problems.

  • Why not BPC?The negatives:You must spend more time trying to control the pests. (More time spent=less money)Research must be done to find the right bugs/plants for the job.If the wrong insects/plants are used, then you can end up seriously harming the ecosystem.

  • Harming the EcosystemIn Hawaii, the mongoose was imported to stop the spread of rodents. The mongoose ate many rodents, but ate other things too(not good.)

  • Lady Bug vs. Preying MantisWhat would you choose?You are a farmer in Nova Scotia and you have been having problems with aphids. You have decided to use BPC instead of chemicals to help the aphid problem. You must choose, based on the information provided, which predator will be the best for you.
