Neem seed extract inhibited growth and development of gypsy moth, Lymantria disbar (L.), larvae. Untreated control larvae increased their weight by ≍40-fold by day 14, whereas insects treated with 0.10% neem and 1.00% neem weighed ≍30% and ≍4%, respectively, of the average weight of the untreated larvae. By day 14, 99% of the controls were in the fifth stage and 1% were prepupae. After treatment with 0.10% neem almost one-third of those larvae were still in the fourth stage, whereas larvae… Expand
Effect of Neem extract on Lymantria dispar L. (Lepidoptera: Lymantriidae) and Leptinotarsa decemlineata Say. (Coleoptera: Chrysomelidae)
TLDR
As a biological, plant-derived preparation, Neem could be suitable for integrated pest management (IPM) programs, especially in small orchards, parks, and tree rows in urban environments and on small private gardens. Expand

The effects of neem seed kernel extract (NSKE), neem oil (NO) and nucleopolyhedrovirus (NPV) of the Spodoptera litura Fabricius (Lepidoptera: Noctuidae) on the mortality, feeding and development ofExpand
EVALUATION OF NEEM (AZADIRACHTA INDICA A. JUSS) OIL, NEEM SEED WATER EXTRACTS AND BAYTHROID TM AGAINST BOLLWORMS AND EGG PARASITOID TRICHOGRAMMA CHILONIS
TLDR
Neem oil at 2% and neem seed water extracts at 3% remained effective up to 336 hours after spray; as significantly lower number of bollworms larvae settled on bolls treated with 2% neem oil and 3% neam seed water extract. Expand
Some biochemical effects of plant extracts in the black cutworm, Agrotis ipsilon (Hufnagel) (Lep., Noctuidae)
TLDR
It seems that the obserserved disturbances of nutrient content and carbohydrate digestive enzyme activities might affect larval growth. Expand
Response of the gypsy moth Lymantria dispar L. (Lepidoptera, Lymantriidae) to the content of allelochemicals in birch leaves (Betula pendula Roth)
Structural and functional characteristics of the gypsy moth population in a birch forest were found to be correlated with the level of defoliation and the content of allelochemicals in the foliage.Expand
Effects of Spinosad and Neem on the Efficacy of a Nucleopolyhedrovirus on Pickleworm Larvae1
TLDR
These biorational insecticides are compatible with nucleopolyhedrovirues and may be useful in management of this primary pest of cucurbits. Expand
The efficiency of some plant extracts against Agrotis ipsilon (Lepidoptera: Noctuidae) regarding to their activity on vital biochemical parameters
TLDR
Results recommend that tested insecticidal compounds at such low concentrations can hinder A. ipsilon larval duration, food consumed, and enzymatic possessions, so, the tested Insecticidal materials could be applied as a control strategy for this pest. Expand
Effects of azadirachtin-based insecticides on the egg parasitoid Trichogramma minutum (Hymenoptera: Trichogrammatidae)
TLDR
Results indicate that azadirachtin is compatible with T. minutum during egg parasitism at operational dosages and has a small but significant effect on developmental success. Expand
Increasing the efficacy of the cotton leaf worm Spodoptera littoralis nucleopolyhedrosis virus using certain essential oils
TLDR
The results suggested that the combination treatment of orange oil and SpliMNPV could be used as an effective method for the cotton leaf worm, Spodoptera littoralis (Boisd.), management. Expand
Side‐effects of neem (Azadirachta indica) products on insect pathogens and natural enemies of spider mites and insects *
TLDR
The use of neem‐based pesticides can be a substantial contribution towards preservation of biodiversity in ecosystems in spite of the fact that they are not completely safe to all stages of beneficial nematodes, mites, and insects. Expand
