The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.

Control methods were carried in Baltiem district, Kafrel-Sheikh Governorate from times during both Spring and Summer plantations, 2012. The efficacy of these control methods was recorded on the basis of reduction percentage in the larvae after periods of 2, 5, 7, 10 days from each application. The obtained results revealed that the highly increase in the reduction was occurred in Summer plantation verification with the number of larvae in Spring plantation. Based on reduction percentages in the number of larvae, the efficacy of the tested treatments could be descendingly arranged as follows Bacillus thuringiensis + Neem, B. thuringiensis + Trichogramma evanescens + mass trapping, B. thuringiensis + Trichoderma harzianum, T. harzianum + Neem, T. harzianum + mass trapping and T. evanescens + Neem. The corresponding value were 91.88, 90.18, 87.89, 85.69, 80.75 and 84.82 % for the above treatments, during Summer plantation and 88.49, 86.03, 84.78, 83.01, 79.88 and 82.82 % during Spring plantation.On the other hand, using baited traps of males moths using synthetic sex pheromones recorded the highest relative percentage were 10.91 and 10.76 % in Spring and Summer plantation, respectively. Where the lowest one recorded 2.74 and 2.71 % in Spring and Summer plantation. The highest healthy yield production recorded 9.555 ton/feddan in case of using B. thuringiensis + Neem, whereas the lowest healthy yield production recorded 5.580 ton/feddan when using T. evanescens + Neem.The corresponding general means of cost benefit 3317 and 1589 L.E/feddan, respectively. On the other hand, the healthy yield production in the untreated plot recorded 1.555 ton/ feddan.
Biological control agents is considered as an important factor of IPM strategy, efforts have been and are still being made to evaluate the effects of residual insecticides on natural enemy population. The commercial production of predators and parasitoids, using factitious hosts, such as, the Angoumois Grain Moth (AGM), Sitotroga cerealella (Olivier), the Mediterranean Flour Moth (MFM), Ephestia kuehniella Zeller and the Rice moth (RM), Corcyra cephalonica (Stainton) proved successful approach. This study involved, technical improvement for egg laying, collecting the eggs and testing of different collection techniques, manual and automatic rotation cylinders were studied. The main finding indicated that, the total eggs laying during 55 days from 21 trays containing Sitotroga adults reached 478.072 g in case of the mechanical cardboard, while it introduced 289.46 g in case of the manual rotation. Moreover, the patent no. of 2005020071 under the title " Egg laying collecting machine for the hosts of mass production" was obtained during this work modified machine for egg laying and collection for the mass production of insect host.
Destructive effects of conventional insecticides on environment have created a necessity to introduce bio-rational products in pest control programs. Effectiveness of bio-pesticide (Beauvaria bassiana), natural oil (anti-insect), a botanical extract (nimbecidine) and malathion insecticide was evaluated against Thrips spp. and Bemisia tabaci attacking tomato in Kafr El Sheik, Egypt. The trial was conducted during two successive seasons; 2017-18 in a total area of 4912 m 2 cultivated with tomato cultivar zero 42. The experiment was set up in a randomized complete block design with five replications for each treatment. Yellow sticky traps were used to monitor population of both pests before and after spraying, in addition, their numbers on plants were counted. Results revealed that highest control rates of both pests were recorded after the fourth day of each spraying. Long inter-applications periods decreased effectiveness and the greatest control resulted when three consecutive sprayings were applied. Malathion achieved the highest suppression of both pests. Within the bio-rational pesticides, nimbecidine gave the greatest thrips control whereas products showed no significant difference for whiteflies. The study recommends those bio-rational compounds to join Integrated Pest Management programs of both pests in Egypt, taking into consideration spraying for 3 consecutive times with at least 5 days intervals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
