RAGA, Adalton; FILIPE MUNIZ BASILLI, João  and  ZANIBONI SOARES, Daniel. Oviposition pattern of citrus blackfly Aleurocanthus woglumi (Hemiptera: Aleyrodidae) on citrus plants. Idesia [online]. 2012, vol.30, n.2, pp.111-114. ISSN 0718-3429.

The objective of this study was to evaluate the behavior of Aleurocanthus woglumi Ashby oviposition in citrus plants. The study was conducted in an orange orchard installed in the municipality of Artur Nogueira (State of São Paulo, Brazil). We observed 16,125 egg masses from 256 fully expanded leaves. From 1,280 egg masses of A. woglumi (five per leaf) we obtained a minimum of 8, a maximum of 50 and an average of 28.42 eggs per mass. Approximately 83% of the egg masses had from 16 to 41 eggs. The egg masses in the south quadrant were significantly more numerous than in the west quadrant and similar to the remaining quadrants. No differences were detected among the average number of eggs per mass in each quadrat.
