Schistosomiasis is a parasitic infection that induces severe complications and remains silent for a long period of time. Schistosoma haematobium and Schistosoma mansoni are the incriminating agents along with freshwater gastropod mollusks as the disease vectors. In order to map the potential for schistosomiasis transmission in present and future, pathogen and vector occurrence data were collected from the literature and...

Maize (Zea mays) is the most stable and nutritious food in Ethiopia. Sitophilus zeamais is a serious pest of stored maize. The present study evaluated the effects of botanical powders on F1, F2 and F3 progeny emergence under laboratory condition. The experiment was laid out in complete block design with three replications and twelve treatments. Ten pairs of maize weevils were exposed to botanical powders of five plant...
Do non-diapausing insects respond to different photoperiods: Spodoptera littoralis?
Article in Press
Photoperiod is a great factor in determining the developmental pattern (continued development vs. suspended development, i.e, diapause) of many insect pests. The cotton leaf worm, Spodoptera littoralis (Boisd.) is non-diapaused insect. Knowledge about how developmental pathway of S. littoralis responds to photoperiod is necessary for mass rearing of the pest and its parasitoids and may suggest new control management. The...

The study was conducted at Dilla University Botanical and Ecotourism garden to examine the diversity of termite species, their seasonal feeding activities and impact on indigenous plant collections at Dilla, Ethiopia. A total of 147 quadrants of 5 m2 (2.24 m x 2.24 m) were laid at every 10 meters interval at three randomly selected sampling sites during consecutive wet and dry season. All sections of the quadrants were...

The study evaluated the efficacies of four novel indigenous biopesticides in managing cucumber (Cucumis sativus L.) pests and nematode disease. The trial laid out in a split-plot arrangement in Randomized Complete Block Design, was carried out on a field undergoing organic conversion at the Federal University of Agriculture, Abeokuta. The main plot comprised four biopesticides made from ginger (Zingiber officinale),...

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....

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...
Survey of insect pest infestations of important medicinal plants in Central India
Article in Press
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...

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)
Article in Press
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).

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...
