1 The Effect of Cold Storage on the Survival of Coccinella undecimpunctata Cary Langley Biology Department Eastern CT State University

2 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 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 Stages Used

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 Biological Control Agents
