Effects of neem leaf extracts on Lepidopteran pest species attacking Solanum macrocarpon L. (Solanaceae) in southern Togo

Lepidopteran pests cause considerable damage to Solanum macrocarpon Linnaeus (Solanaceae). Their control by the use of botanical extracts is a promising alternative to improper use of chemical insecticides. The objective of this study was to evaluate the effects of three doses of leaf extract of the neem tree, Azadirachta indica Adrien-Henri de Jussieu (Meliaceae) against Lepidopteran pest species that attack S....

A comparison of the effectiveness of the aqueous extracts of milkweed, castor bean and fennel in the biocontrol of root-knot nematode in tomato

A study was conducted to find out the effect of three plant aqueous extracts against root-knot nematode (Meloidogyne javanica). In laboratory assays eggs and second-stage juveniles of M. javanica were exposed to aqueous extracts from leaves of milkweed (Calotropis procera), castor bean (Ricinus communis) and seeds of fennel (Foeniculum vulgare). The result of the laboratory experiment showed that all the extracts increased...

Efficacy of Pesticides on Two-Spotted Spider mite (Tetranychus urticae Koch) (Acari: Tetranychidae) in Laboratory at Haramaya, Eastern Ethiopia

Screening chemicals in a well designed experiment can serve as a short-term solution, and organic pesticides identified can be integrated with other options in the long-term. The study was conducted in Plant Protection Laboratory of Haramaya University under 25±2 oC, 70±5% RH during 2016. The objective was to evaluate the efficacy of some pesticides at the manufacturers’ recommended rate against Tetranychus urticae in...

Ovicidal, oviposititon deterrence and biological activity reduction effects of Birbira (Millettia ferruginea) on Diaondbackmoth (Plutella xylostella L.) (Lepidoptera: Plutellidae).

The study was carried out to determine the efficacy of Birbira (Millettia ferruginea) (Hochest) Baker tree seed solvent extracts on Diamondback moth (Plutella xylostella L.). Leaf dipping method was used to run both assays by using extracts from Birbira seeds kernel powder in water (w/v):0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2 and 1.4 mg/ml. In the assay, full Oviposition deterrence was recorded at the higher rates of polar...

Experimental Analysis of Ecomomic Action Level of Tomato Leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) on Tomato Plant under Open Field

Tuta absoluta is measured as a key pest of tomato both in the field and under greenhouse conditions. It is causing heavy economic impact by larval which feeding leaves and fruits. Information on tomato leafminer economic injury levels (EILs) and economic thresholds (ETs) is relatively limited. Studies were conducted during 2015 to 2017 to determine EILs and ETs on open field is required for more effective management. The...

Biological aspects and predation of Pygidicrana v-nigrum Serville, 1839 against the Mediterranean fly

The biological development and quantification of Pygidicrana v-nigrum consumption was evaluated taking as prey the immature stages of Ceratitis capitata. The dermapterous insect, when ingesting C. capitata larvae, reached its nymphal period, on average, at 228 days. The lowest nymphal viability of P. v-nigrum occurred in its 1st instar when fed with larvae, reaching a value of 85%. The food provided did not influence the...
