Effect of integrating entomopathogenic fungi and botanical extracts against Russian Wheat Aphid, Diuraphis noxia Mordvilko (Hemiptera: Aphididae) in West Showa, Ethiopia.

Ethiopia is the only country in Sub-Saharan Africa where smallholder wheat production meets more than 70% of the national consumption demand. Russian wheat aphid (RWA; Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae) is one of the major insect pests of wheat throughout the world including in Ethiopia. Wheat yield loss due to RWA damage in Ethiopia was estimated to be 70%. Therefore, the present study was carried out to...

Persistent of low-level diapause and generation effect in Microplitis rufiventris wasps under mass rearing conditions

The solitary endoparasitoid, Microplitis rufiventris is considered one of the principal wasps on the cotton leaf moth, Spodoptera littoralis larvae. It has a strange sort of obligate diapause. The data present an evidence of persistent low-level diapause throughout the year and every year that observed under mass rearing conditions. When continuous rearing was done throughout the year at 25ºC and 12/12 hours L/D , a small...

Entomological and Transmission Risk Indices of Bancroftian Filariasis Vectors after Community wide Long lasting Insecticide-treated bed net (LLIN) Intervention trials in Ebonyi State, Nigeria

Bancroftian filariasis in Nigeria is endemic with 22.1% of the population at risk of infection. The main mosquito genera implicated with the transmission are Anopheles and Culex. To compare the infectivity rates and transmission potentials after long - lasting insecticide - treated bed net (LLIN) intervention, we conducted study on the vectors between the high transmission (rainy) and the low transmission (dry) seasons....

Effect of cowpea cultivar, planting date and application of insecticide in the management of cowpea insect pests in South Eastern Sierra Leone.

Cowpea (Vigna unguiulata) is attacked by a wide spectrum of insect pests that ravages the crop in the field at different growing stages sometimes resulting into complete crop failure. In order to reduce insect pest damage, increase cowpea seed yield and reduce the indiscriminate use of insecticide, it was necessary to conduct an experiment geared towards integrating cowpea cultivar with date of planting alongside minimal...

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...

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...
