Dear Subscribers,

Please see a message form Christian Theirfelder and the attached paper:*
Friends or foes? Population dynamics of beneficial and detrimental aerial
arthropods under Conservation Agriculture *by Mlangha et al. In Biological
Control.

Thank you Christian for sharing.

Apologies for any cross-posting.

*Conservation Agriculture is an ecosystem approach to regenerative
sustainable agriculture and land management based on the practical
application of context-specific and locally adapted three interlinked
principles of: (i) Continuous no or minimum mechanical soil disturbance
(no-till seeding/planting and weeding, and minimum soil disturbance with
all other farm operations including harvesting);  (ii) permanent
maintenance of soil mulch cover (crop biomass, stubble and cover crops);
and (iii) diversification of cropping system (economically, environmentally
and socially adapted rotations and/or sequences and/or associations
involving annuals and/or perennials, including legumes and cover crops),
along with other complementary good agricultural production and land
management practices. *

Dear Colleagues,

Biological control in cropping system has become an increasingly hot topic,
specifically in CA systems where we try to reduce the environmental
footprint – this data was taken before the Fall Armyworm became a major
pest in Africa. As you can see we are slowly transgressing to R. Thanks to
Blessing and all teachers involved who helped us in getting that far…
