insecticidal activity of 23 essential oils and their major compounds against adult lipaphis pseudobrassicae (davis) (aphididae: homoptera).	essential oils from 23 species of plants comprising 14 genera and 4 plant families were obtained by clevenger-type water distillation. the major compounds in these essential oils were identified with gc-ms and their insecticidal activity against adult turnip aphids, lipaphis pseudobrassicae (davis), tested with dosage-mortality bioassays. we examined mortality only for viviparous adults because sizeable aphid populations on crucifer (brassicaceae) hosts are largely produced by these wingless, pa ...	2005	16075408
[first record of lipaphis pseudobrassicae davis (hemiptera: aphididae) and its association with predator insects, parasitoids and ants in kale (cruciferae) in brazil].	this study describes the fauna of predator insects, parasitoids and ants associated with aphids on kale (brassica oleracea l. var. acephala d.c.) in organic system. the aphid was identified as lipaphis pseudobrassicae davis, and this is the first record of the species attacking kale in brazil. primary parasitism by diaeretiella sp. and aphidius sp. and hyperparasitism by aphydencyrtus sp., alloxysta sp., pachyneuron sp. and syrphophagus sp. were observed. twenty species of coccinellidae were col ...	2006	17061806
brassica aphid (hemiptera: aphididae) populations are conditioned by climatic variables and parasitism level: a study case of triângulo mineiro, brazil.	cosmopolitan pests such as brevicoryne brassicae, lipaphis pseudobrassicae, and myzus persicae (aphididae) cause significant damage to brassicaceae crops. assessment of the important biotic and abiotic factors that regulate these pests is an essential step in the development of effective integrated pest management programs for these aphids. this study evaluated the influence of leaf position, precipitation, temperature, and parasitism on populations of l. pseudobrassicae, m. persicae, and b. bra ...	2017	28316286
influence of host quality and temperature on the biology of diaeretiella rapae (hymenoptera: braconidae, aphidiinae).	biological features of diaeretiella rapae (mcintosh), an aphid parasitoid, are conditioned by temperature and host. however, studies of host quality changes due to temperature adaptability have not been performed previously. therefore, this study evaluated the adaptability of lipaphis pseudobrassicae (davis) and myzus persicae (sulzer) to high temperature, high temperature effect on their quality as hosts for d. rapae, and on parasitoid's thermal threshold. aphid development, survivorship, fecun ...	2017	28881958
