Geomorphologic and allometric variations in the populations of adult cocoa moth, Ephestia cautella (Lepidoptera: Pyralidae) from Southwestern Nigeria

Damage by the tropical warehouse moth, Ephestia cautella (Walker) to stored plant products especially dried cocoa beans is enormous. This is expressed in holing with frass and webbing of the beans leading to nutritional loss; turning the valuable commodity into powder and reducing the value in the export-import market. Effective management of the pest is contingent upon correct identification and bioecological expressions...

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...

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...

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...

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...
