Abstract
Ibrahim, A.K. 2023. The Adult Tendency of Eleven-Spotted Ladybird, Coccinella undecimpunctata for Preference of Certain Type of Aphid. Arab Journal of Plant Protection, 41(4): 369-374. https://doi.org/10.22268/AJPP-41.4.369374 This study explored the extent of eleven ladybirds preference to a specific aphid species, i.e., Aphis fabae, A. nerii, Macrosiphoniella sanborni and Hyalopterus pruni and the extent of the host plant and type of prey in attracting predators. Results obtained showed a preference of adult ladybird predators for H. pruni, Macrosiphoniella sanborni, Aphis nerii, whereas Aphis fabae was the least attractive and consumed by predators. The consumption rate of apricot aphid reached 23.66% in the presence of aphids and the host plant together. The most attraction to apricot leaves in the presence of the plant only was 55.90%. The time required for ladybirds to reach the first prey was 2.15 min for the apricot aphid in the presence of aphids and plants together. Furthermore, the ladybirds reached the prey within 1.30 minutes in the presence of aphids only. The predation efficiency of the four larval instars varied according to the type of aphids. It reached 86.30% for the fourth larval instar on apricot aphids and was the highest compared with the rest of the aphid species, which ranged between 7.10 and 84%. The general average predation efficiency values on aphids were 57.45% for H. pruni, 53.13% for Macrosiphoniella sanborni, 46.05% for A. nerii and 41.16% for A. fabae. The relative efficiency values for the larval instars reached 12.25, 42.27, 60.20 and 83.50%, respectively, for the first, second, third and fourth instars. This was confirmed by the high attraction of predatory ladybirds towards H. pruni and Macrosiphoniella sanborni, compared to Aphis nerii and Aphis fabea. The proportion of aphids consumed by ladybirds in the presence of the plant host was highest for H. pruni and lowest on Aphis fabea. Keywords: Aphids, ladybugs, plant host, predation efficiency
