The efficacy of extracts from two Piperaceae species, Piper nigrum L. and P. tuberculatum Jacq. were evaluated using larvae and adults of the Colorado Potato Beetle Leptinotarsa decemlineata (Say). Young larvae and neonates were the most susceptible; a 24-h LD(50) of 0.064% extract of P. tuberculatum was determined for 4-day-old larvae, while 0.05% extract of P. nigrum reduced larval survival u...

Tuba root is one of the plants that contain rotenone, which an active ingredient non-specific insecticides. Rotenon has a very strong toxic power, but safe from health and environmental perspective because it easily degraded does not accumulate in organism fat. There are many types tuba plants, most commonly used Derris ell i ptica . also been lot research on Indonesian roots as fish poisons bo...

Thepotatopsyllid,Bactericera cockerelli(Sulc) (Hemiptera:Triozidae), is a seriouspest of potatoes (Solanum tuberosum L.) that can cause yield loss by direct feeding on crop plants and by vectoring a bacterial pathogen, Candidatus Liberibacer psyllaurous. Current pest management practices rely on the use of insecticides to control the potato psyllid to lower disease incidences and increase yield...

1064 Identification of Articles of Botanical Origin by High-Performance ThinLayer Chromatography Procedure. High-performance thin-layer chromatography (HPTLC) is widely used for botanical identification. Variability of the chromatographic conditions has the potential to significantly impact the results. This informational general chapter describes, with illustrations, the need to control the re...

After more than 70 years of chemical pesticide use, modern agriculture is increasingly using biological control products. Resistances to conventional insecticides are wide spread, while those to bio-insecticides have raised less attention, and resistance management is frequently neglected. However, a good knowledge of the limitations of a new technique often provides greater sustainability. In ...

Oebalus poecilus (paddy bug) is a destructive rice pest in Guyana that currently controlled with synthetic chemical pesticides. Increasing resistance rates and farmer's overuse of pesticides have resulted economic ecological issues for Guyanese farmers. Amid growing concerns, this experiment aimed to investigate the use alternative botanical extracts from leaves Momordica charantia (Baan-Carail...

The excessive and indiscriminate uses of synthetic insecticides usually lead to many problems human health, environment economics. Therefore, it is a prerequisite search for safe alternatives among which plant extracts products represent effective materials pest control. main goal the present article was searching new control insect pests via disruptive effects these on haemogram immune paramet...

Cocoa pod sucking (Helopeltis spp.) is one of the pests that causes a productivity decrease cocoa in Indonesia. In terms control, many farmers Indonesia are still using synthetic insecticides not environmentally friendly, so intoxicating yam (Dioscorea hispida Dennts) and tropical whiteweed (Ageratum conyzoides L.) used as botanical insecticide friendly.
