Vice Minister Launches Ecological Engineering Initiative in My Tho, Vietnam

Ecological Engineering to enhance local biodiversity and related ecosystem services has been experimented in Tien Giang province with support from the provincial government.  The community experiments in Cai Be and Cai Lay districts showed that rice farms with ecological engineering modifications had significantly higher predators and parasitoids and lower pests.  Total parasitoids and predators in the … Read more

New TV series on ecological engineering begins in the Mekong

Backdrop of the TV series on ecological engineering launching event Entertainment education is a useful means to initiate social change.  When the principles were applied to create the radio soap opera, the 104 episodes broadcast over the Voice of Ho Chi Minh City contributed significantly to farmers’ belief and practices (Heong et al 2008).  Listeners significantly … Read more

Parasitoid Biodiversity Increases in Ecological Engineering Fields of Chainat, Thailand

In Chainat Rice Research Center, we used part of the farm to evaluate the impact of ecological engineering on the biodiversity of arthropods. The areas surrounding the rice fields were replaced with several species of flowering plants and vegetables to provide habitats and nectar resources to natural enemies. Another area of the farm was left as … Read more

Parasitoid Density Higher in Farmers’ Ecological Engineering Fields; No Difference in Species Biodiversity in Cai Be, Tien Giang, Vietnam

In Cai Be District we initiate ecological engineering fields through farmer participation.  Thirty-five (35) farmers in a village were encouraged to cultivate several species of nectar rich flowers along the bunds to increase parasitoid biodiversity. Another area of about 20 ha was left as the control field. We monitored the parasitoids by various sampling techniques … Read more

Searching efficiency of egg parasitoid enhanced by sesame flowers

Regulatory ecosystem services are important in keeping pest populations below damaging levels.  In rice ecosystems, one group of arthropods that performs this function well is the egg parasitoids. These are tiny hymenopterans that have long ovipositors that can pierce through the plugs protecting the eggs that the planthopper females insert into the stem tissues.  Being … Read more

Rice fields with sesame grown on the bunds have higher natural enemies in Jinhua, China

Ecological engineering involves restoring floral biodiversity to provide resources for natural enemies.  We established sesame plants along the bunds of a rice field of about 0.5 hectares and monitored the natural enemies.   A neighboring farmer’s field without the sesame was used as a comparison. Sesame was selected because of the flowers last a long period, … Read more
