Trichogramma, a biological solution against the borer
The specimens were identified as Trichogramma evanescens which is the third biocontrol agent of apple codling moth collected and being reared under PRMP in Quetta. The identification also confirms that this is the first ever record for Pakistani fauna and a major achievement of PRMP project interventions in Quetta.
Previously, two larval indigenous parasitoids of apple codling moth, namely Dibrachys microgastri and Elasmus sp. nr. johnstoni, were successfully recorded for the first time in Balochistan. They were found to have attacked the larvae of codling moth in corrugated paper technology at two sites. The first utilizing Natural Enemy Field Reservoirs (NEFRs) at the Agriculture Research Institute (ARI), Sariab Road, Quetta, and the second in corrugated paper technology at a project site in Kuchlak. These biological control agents (BCAs) are being mass produced and released in orchards at project sites in Balochistan.
Dr Sabyan Faris Honey, Project Manager, PRMP, expressed that codling moth was recorded as the most serious insect pest of apple industry in Balochistan, when the project conducted the baseline survey in 2015, and that the discovery of this biocontrol has been made possible due to hard work of PRMP project staff.
In addition, Dr Babar E Bajwa, Regional Director of CABI Central and West Asia, added that while apple codling moth has its deleterious effects on apple trees (which poses economic threat to apple production in the region) CABI is committed to delivering its best for the benefit of farmers in the region.
This involves the empowerment of the farming community through sustainable agricultural practices and the first record of this biocontrol agent is a major breakthrough to further strengthening the biological control programme for the sustainable management of apple pests.if you need more info just visit this site trichogramme.
A week or two later, instead of a wee caterpillar, an adult wasp hatches out of the egg shell. This is known as parasitism; Trichogramma is a parasitoid wasp. Other species of parasitoid wasps will lay their eggs in or on caterpillars, spiders, grubs, maggots, eggs of other insects, you name it. There are estimated to be more than half a million species of parasitoid wasps, each with their own particular preferences of where to lay eggs. There is a whole world of these tiny creatures out there that most are not aware of.
