Some experiments indicate the ability of coccinellids to significantly suppress aphid abundance. Exclusion of predators by caging aphid-infested plants has repeatedly resulted in higher aphid populations and greater aphid population growth rates. However, aphidophagous coccinellids have never proved effective in controlling aphid populations in the field. To resolve this apparent contradiction, a field experiment was used to determine the effectiveness of two coccinellids, Coccinella septempunctata bruckii and Harmonia axyridis in suppressing populations of the aphid, Aphis gossypii, on shrubs of Hibiscus syriacus under natural conditions.

Tento článek se zabývá testem úspěšnosti dvou druhů sluníček Coccinella septempunctata bruckii a Harmonia axyridis při kontrole mšice Aphis gossypii na keřích ibišku v přírodních podmínkách.
