Possible storage of Coccinella undecimpunctata (Col., Coccinellidae) under low temperature and its effect on some biological characteristics A. H. Abdel-Salam and N. F. Abdel-Baky The Journal of Applied Entomology Vol. 124:

3. Coccinella undecimpunctata
Common Name = Eleven Spotted Lady Beetle
Predators of
 Aphids Whiteflies Weevils
Biological Control Agents
Cold Stored for Shipping Purposes

4. Why Study Cold Storage of Coccinella undecimpunctata
Survival of Cold Temperatures
Developmental Stages Surviving the Cold
Developmental Stage Best Used for Short and Long-Term Shipping

5. Cold Storage Effect Egg First, Second, Third & Fourth Larval Instars
Stages Used
Egg
First, Second, Third & Fourth Larval Instars
Pupae
Adults: Directly After Eclosion Without Food Five Days After Eclosion With Food Ten Days After Eclosion With Food
Refrigerated At 6°C
Refrigerated For 7, 15, 30, 45, 60 Days

6. Results of the Study
Hatching Success of Refrigerated Eggs

15. Final Thoughts
Eggs, Larval Instars & Pupae Survived Short-Term Storage, 7 Days
Adult Storage More Long-Term, 45 Days Due to Diapause
Simple Method for Storing Large Numbers
Easy Shipping
Synchronization With Insect Pest
Suppress Insect Pests When Required

16. In Conclusion Cold Stored Fed Adults Are Most Receptive
