How can the pest direction system be made more robust to advantageously cover be blighter such as aphid and thrips ? And what can be done about the rise of invasive stink bug like Nezara that pose a threat to the sustainability of the pest management system of rules ? These question are predominant among many harvest groups in gardening . The four - yr research project ' PPS Establishment and Retention of Predatory Bugs and Lacewings in Horticulture ' aim to allow answers . The project officially began on April 24.The newfangled PPS is focusing on developing refinement systems in which three chemical group of lifelike enemies can lay down themselves : predatory shield bugs ( especially Podisus maculiventris ) , lacewings , and Nabis predatory bugs . The end of the project ? produce a ' standing ground forces ' with these predators to ensure a wide variety of pests .
Various Sub - areasThe PPS consist of various sub - areas that will sometimes be carried out simultaneously , but often consecutively . As an example , one of the enquiry objectives is to gain more brainstorm into the behaviour of the predatory bug Podisus maculiventris in its dissimilar stages . What food for thought author can you use to flow this predatory bug to ameliorate its selection and activity in the greenhouse ?
For lacewings , it is theorise that add up plants that produce root of extrafloral ambrosia into the greenhouse may help . The use of kairomones and the institution of refuges can assure that unlike types of lacewings can show themselves easily in crop such as peppers , strawberry , eggplants , gerberas , and kalanchoes .
Using Nabis predatory bugs is unexampled in gardening . Researchers will test which pests the Nabis predatory germ direct , as well as invstigating whether providing habitats and food can avail establish these hemipteran in the greenhouse environment .
to boot , it will be examined as to whether clean-cut causes can be identified for the less establishment of Orius , focused on the pepper crop group .
participating Steering of the Research Project by the BCOAll crop groups co - financing this labor attended the get-go meeting . inquiry leader Gerben Messelink expressed his satisfaction with the active involvement and comment from so many political party . " This demonstrates broad documentation across a spacious reach of crops for this type of enquiry . "
