ladybird beetles are of a special standing in aphid biological control. they attack different aphid species and play an important role in suppressing aphid populations. one of the most conspicuous coccinellids namely hippodamia variegata, occurs in such different crops as alfalfa and vegetables. life history parameters of this predator at 25 ± 1 ?c and 16:8 (l: d) photoperiodicity were evaluate...
Interest in essential oils with pesticidal activity against insects and pests is growing. In this study, essential oils from different parts (leaves, twigs and seeds) of Cinnamomum camphora L. Presl were investigated for their chemical composition, and insecticidal and repellent activities against the cotton aphid. The essential oils, obtained by hydrodistillation, were analyzed by GC×GC-TOFMS....

We present here the first complete genomic Aphid lethal paralysis virus (ALPV) sequence isolated from cucumber plant RNA from East Timor. We compare it with two complete ALPV genome sequences from China, and one each from Israel, South Africa, and the United States. It most closely resembled the Chinese isolate LGH genome.
