| description | The objective of biological control is to reduce chemical treatments on crops. To reduce
aphid attacks with the use lady beetles is a positive, respectful alternative since it can maintain
an ecological balance. In order to achieve this objective, the Algerian seven-spotted
lady beetle (Coccinella algerica) was bred under laboratory conditions, and biological parameters
of this species were studied. The study, conducted from April to May, showed that
temperature and relative humidity greatly affected the incubation time of C. algerica eggs.
Egg fertility was very high and reached up to 100%. The present work highlighted that the
developmental cycle of this lady beetle from the Beni-Douala area (Tizi-Ouzou) passes
through five larval stages. The fifth instar larva was recorded for the first time. Indeed, all
studies carried out to date have identified only four larval stages in this |
