Pre Treatment

Okra (Abelmoschus esculentus L.) is an essential vegetable crop with good nutritional significance. Insect pests are the major threat for poor production of the okra crop. Thrips of vegetable crops are known to be serious pests on a wide range of fruit, vegetable, flower, and agronomic crops. The present field study was carried out to know the efficacy of different insecticides (acetamiprid 19% weightable water (ww), lambda 25% ww, colarphipare 32% ww, lambda 2.5% ww and abamectin 1.3% ww) against Thrips, Thrips tabaci (Lindeman) on okra crop during the year 2019, and observations against T. tabaci (Lindeman) were recorded after 24 hrs, 48 hrs, 72 hrs and 07 days of each spray in all the treatments. The pre-treatment count of thrips on okra was non-significant (P > 0.05); while the evaluated efficacy of different insecticides against thrips was significant (P < 0.01). It was noted that all the insecticides showed their highest efficacy after 7 days of spray and acetamiprid 19% weightable water (ww) was more efficient to combat the T. tabaci as compared to other pesticides that produced field efficacy of 73.92 and 74.91% against thrips after 7 days of 1st and 2nd spray respectively. Abamectin, 1.3% ww, was reasonably successful, yielding 53.81 and 56.66% field efficacy against T. tabaci (Lindeman) after 7 days of first and second spray. Also, moderately effective was colarphipare 32% ww, which developed field effectiveness of 56.41 and 61.49% against T. tabaci (Lindeman) after 7 days of first and second spray, respectively.

Systemic Insecticides

Abstract Use of systemic insecticides that can be injected either into the root system or trunk of woody plants provides several potential advantages, notably in control of drift during application. Recently, new classes of insecticides with systemic activity have been developed, which may supplant the organophosphate and carbamate systemic insecticides that have previously been available. To evaluate their potential to control insects affecting shade trees, studies were conducted using imidacloprid and abamectin on elm. Soil injections of imidacloprid appeared particularly effective, controlling all three of the target pest species in this study (elm leaf beetle, European elm scale, elm leaf aphid). Both imidacloprid and abamectin also were effective against at least some elm insects when injected into trunks. Persistence of irnidacloprid was unusually long, providing second season control of all elm insect pests, although root uptake following soil injections was slow.

Stage Of Development

Cone-bearing Douglas-fir trees in three localities on Vancouver Island were sprayed with the systemic insecticides Bidrin (0.35 and 0.75%), dimethoate, Sumithion, Meta-Systox-R, and SD 9129 (1.0 and 2.0%) when cones had reached the pendent stage of development. With the exception of Sumithion, all materials gave varying degrees of control over important insect pests of cones in this area, i.e. the gall midge, Contarinia oregonensis Foote, the cone moth, Barbara colfaxiana (Kft.), the seed chalcid, Megastigmus spermotrophus Wachtl, and the scale midge, C. washingtonensis Johnson.

This research work aimed at assessing the metal composition of the cotyledons of Citrullus colocynthis (egusi) and Irvingia wombolu (ogbono) as well as cassava chips sold in open markets in the five states of the South-Eastern Nigeria. These food materials were sampled from 135 stores and markets in three waves (Wet season, Harmattan and Dry season) between February, 2015 and March, 2016 in each of the five states in south eastern Nigeria (Enugu, Anambra, Imo, Abia and Ebonyi). The food materials were analyzed for Zinc, Lead, Copper and Iron using the Atomic Absorption Spectroscopy (AAS) method. The concentrations of these metals were not higher than the maximum permissible limit set by NAFDAC in Nigeria except for Lead in Enugu State ((0.042±0.068 mg/g). The highest quantity of Lead was detected in Citrullus colocynthis (0.039±0.006 mg/g) while the least concentration was detected in Cassava chips (0.009±0.005 mg/g). Lead was detected in samples collected across all the seasons (Wet season, Dry season and Harmattan). The high concentration of Lead in the sampled food materials from Enugu state across all the waves of sample collection that violated the permissible limits of lead set by WHO and NAFDAC is of public health concern. Lead exposure has been shown to cause severe health challenges thus regular monitoring of these toxic heavy metals from foods sold in markets is essential, to prevent their excessive build-up in the food chain. The inference of this study reveals that these food materials sold in the open market are not completely safe for consumption as a result of lead contamination due to poor handling and processing. Findings from this study will be of great help to all stakeholders in this area of interest such as researchers and environmental regulators, relevant government agencies saddled with the responsibility of ensuring the safety of foods consumed in Nigeria.
