“…The effects of cold storage on the fitness of numerous mass-reared parasitoids (López and Botto 2005;Pandey and Johnson 2005;Chen et al 2008) and predators (Abdel-Salam and Abdel-Baky 2000;Gagné and Coderre 2001;Riddick and Wu 2010) have been assessed. However, the effect of cold storage on the fitness of pre-wintering H. axyridis have rarely been documented, except for some studies focusing on survival (Koch et al 2004;Berkvens et al 2010).…”

“…Recently, Riddick and Wu (2010) tested long-term storage of the predatory mite Phytoseiulus persimilis Athias-Henriot with cryoprotectant and carbohydrate chemicals. The possibility of cold storage has been studied for many coccinellids including Coccinella septempunctata L., Adalia bipunctata L. (Hamalainen 1977), C. undecimpunctata L. (Abdel-Salam and Abdel-Baky 2000) and Coleomegilla maculata lengi Timberlake (Gagné and Coderre 2001). Several studies have investigated the cold hardiness of H. axyridis (Ma et al 1997;Watanabe 2002;Koch et al 2004;Berkvens et al 2010), but the effect of cold storage on fitness of the ladybird has rarely been documented.…”

The multicolored Asian ladybird beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is considered an important generalist predator that can be used as a biological control agent against Hemiptera Sternorrhyncha, Thysanoptera, and the eggs and larvae of Lepidoptera, Coleoptera and Diptera. There are currently abundant natural resources of overwintering H. axyridis in Asia and North America. Given its potential as a biological control agent, methods can be developed to increase its effectiveness for pest control. The availability of an adequate cold storage method would enable the use of field-collected pre-wintering ladybirds for pest suppression in the following season. We studied the effect of cold storage (30, 60, 90, 120 and 150 days stored at -3, 0, 3 and 6°C) on survival, fecundity and predation in field-collected populations. The survival of both female and male ladybirds decreased significantly as storage duration increased at -3°C and 0°C. The ladybirds showed more than 80% survival when they were stored for 150 days at 3°C and 6°C. Long-term cold storage had different effects on the fecundity of H. axyridis at different temperatures. Prolonged cold storage at both 3°C and 6°C shortened pre-oviposition duration and had no adverse effect on reproductive capacity as compared to that of unstored individuals. The adults that experienced 90-day storage at 0°C had the shortest pre-oviposition duration and the largest reproductive capacity. The individuals that were stored for 150 days at 3°C consumed significantly more aphids than the unstored ones. Generally, 3-6°C is a suitable temperature for cold storage of the ladybird without any reduction in fitness. This study will help the exploitation and application of pre-wintering H. axyridis for the biological control of insect pests.

“…The predator is one of the dominant species in several crops including maize,16 wheat,17 potato18 and orchards 19, 20. Its polyphagous habits10 improve field survival during periods of whitefly scarcity, and allow successful rearing on a liver diet 21. Furthermore, it can attack several other greenhouse pest species including the green peach aphid, Myzus persicae (Sulzer),22–24 the two‐spotted spider mite Tetranychus urticae Koch25 and eggs of several lepidopteran species 26, 27.…”

Predation efficacy and compatibility of the predatory lady beetles Coleomegilla maculata lengi Timberlake and Delphastus catalinae (Horn) against the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) were studied in laboratory on glabrous fuchsia (Fuchsia hybrida Voss cv Lena Corolla) and pubescent poinsettia plants (Euphorbia pulcherrima Willd ex Klotzch cv Dark Red Annette Hegg). On glabrous plants (fuchsia), fourth-instar and adults of C maculata were the most efficient, both against whitefly eggs and pupae. On pubescent plants (poinsettia), the larger stages of C maculata were negatively affected and less efficient than adults of D catalinae. The presence of plant structure did not affect the voracity of either predator species. Finally, the simultaneous use of both predator species generated inter-specific competition. These results provide recommendations for biological control of whitefly in horticultural greenhouses.

“…Larvae and pupae could safely be stored for 2 weeks and 1 week, respectively, without significant declines in larval survival and adult emergence from pupae. The potential of storing larval stages of Coleomegilla maculata lengi Timberlake was assessed in the laboratory by Gagné and Coderre (2001) using insects cultured for more than 10 consecutive generations on a diet of beef liver and moth (E. kuehniella) eggs. They found that second and third instars stored successfully for 2 weeks, without considerable adverse effects on development and predation potential (i.e.…”
