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...

Induction of tomato plants resistance to Meloidogyne incognita infection by mineral and nano-fertilizer

Nutrients are vital for plant growth as well as disease severity and control. Utilization of nanotechnologies in agriculture sectors is expected to be the ideal material to enhance plant resistance after perception of specific biotic or abiotic signals that is commonly referred to as induced resistance. Three mineral and nano-fertilizer particles were examined for their efficacy as a soil amendment in controlling the root...

Determination of the larvicidal activity of benzoyl thiosemicarbazone and its Ni(II) complex against Aedes aegypti and Anopheles darlingi larvae in Amazonas, Brazil

Due to the resistance of some mosquitoes to pyrethroids insecticides, new synthetic compounds are of great interest for the development of new insecticides against vectors of tropical diseases, especially in the Amazon region. Our aim was to synthesize and evaluate the larvicidal potential of benzoyl thiosemicarbazone and its Ni(II) complex against larvae of Aedes aegypti and Anopheles darlingi. The compounds were...

Effect of azadirachtin pre-treatment on major pests, diseases and yield of seed yam

Pests and diseases infested material of seed yams have led to sub optimal yield levels. Neem was applied as substitute for chemical pesticides and as environmentally safe bio-pesticide to reduce the crops annual loss due to herbivore pests and their resulting diseases. Field trials were conducted during the 2016 and 2017 major planting seasons in four communities each of Ejura-Sekyedumase and Atebubu-Amantin districts of...

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...

Evaluation of residual effects of lambdacyhalothrin WP10 in different surfaces against Anopheles stephensi, in a malarious area, southern Iran

Malaria is one of the public health problems in southern Iran. The main activity of vector control is indoor residual spraying using pyrethrpids. The aim of study was to evaluate the biological assays of lambdacyhalothrin WP10 at different surfaces of wall. The persistency of lambdacyhalothrin WP10 at 25 mg/m2 was studied on different local surfaces of rooms such as plaster and mud surfaces (sorbent) as well as wooden...

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...
