Characterization of the Soil Nematode Fauna of Makerere Hill, Kampala, Uganda.

Soil nematode faunal analysis is necessary to ascertain the health status of the soil ecosystem. Composite soil samples were taken at designated sites; A, B, C and D from the Makerere Hill area, Kampala and analyzed to characterize the nematode fauna status. Soil samples were collected vertically at 0-5cm, 5-10cm and 10-15cm core depths with a 5cm wide soil auger. A total of 7,900 nematodes were collected from the study...

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...

Survey of insect pest infestations of important medicinal plants in Central India

Seven species of medicinal plants viz. Withania somnifera, Abelmoschus moschatus, Chorophytum borivilianum, Rauvolfia serpentina, Andrographis paniculata, Gloriosa superba, and Emblica officinalis were surveyed in twenty three different sites of Central India. The insect pests damaging to these target species of medicinal plants were collected, reared and identified to species level on the basis of available literatures...

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...

Antidiabetic effect of Lupine turmos compared with antidiabetic drug (Glibenclamide)

Lupines turmos plants had been used by some Sudanese patients with type 2 diabetes, and Glibenclamide, an anti-diabetic drug had been the commonly used one. This study deals with the determination of the biological effects of L. turmos, used traditionally by Sudanese patients in comparing the anti-diabetic drug (Glibenclamide). This study focuses on type 2 diabetic patients who use some plants as treatment without any...

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...

IMPACT OF ENVIRONMENTAL FACTORS ON RICE LEAFFOLDER, CNAPHALOCROCIS MEDINALIS (LEPIDOPTERA: PYRALIDAE) POPULATIONS

The present study was carried out to study the population occurrence and the influence of environmental factors on Cnaphalocrocis medinalis population dynamics for the four consecutive years 2011 to 2014. The population initiated late August and early September. It built abruptly after appearance for the years 2013 to 2014, then maintained till the end of October for the year 2013 while for the year 2014 light trap catches...

Species composition and status of insect pests of stored maize in southern Ethiopia

Maize is a major staple food and feed source for millions of people of Ethiopia. However, insect pests are among the most important biotic constraints of it in storage. Assessment of species compositions and status of insect pests of stored maize grains in four traditional storages over three storage season was conducted in southern Ethiopia in the years 2013/2014 and 2015/2016. The assessment was made from 1 kg of samples...
