Abstract:
Chemical insecticides often have negative impacts if they are not used wisely. The use of bioinsecticides is an alternative to overcome this problem. The aim of this research is to determine the efficacy of several bioinsecticides on the mortality of the insect pest Clauges glaculalis which attacks the pulai plant (Alstonia angustiloba Miq.) on a laboratory scale. The research was carried out at the Laboratory of the Western Indonesian Plantation Forest Research and Development Center (BP2HT IBB) Palembang, using an experimental method with a Completely Randomized Design (RAL) consisting of 11

Abstract:
Insecticidal seed treatments are used commonly worldwide to protect seedlings against root feeding insects. Organophosphate insecticides that have been used for seed treatments are being phased out and replaced with neonicotinoid insecticides. Concerns about the environmental impact of neonicotinoids have prompted a search for alternatives. Microbial insecticides are a biological alternative for seed treatments to target root feeding insects.

ABSTRACT Insect pests have remarkable capacity to develop resistance to insecticides. More than 600 species of plant feeding insect pests have developed resistance to insecticides. Management of insecticides resistance offers great promise as a complementary extension of integrated pest management (IPM). Insecticide resistance management (IRM) attempts to prevent or delay the development of resistance. A revival of interest in the use of microbial agents, especially entomopathogenic fungi in combination with sublethal doses of insecticide is increasing in insecticide resistance management. Int

Systemic insecticides are recognized as one of the drivers of the worldwide bee decline as they are exposed to them through multiple pathways. Specifically, neonicotinoids, some of which are banned for outdoor use in the European Union (EU), have been pointed out as a major cause of bee collapse. Thus, farmers have had to look for alternatives for pest control and use known insecticides or new substances reportedly less harmful to bees.

Abstract Bacillus thuringiensis formulations and conventional insecticides were evaluated for efficacy against larval ECB in whorl stage field corn. All plots were planted without soil insecticide on 16 May. The experimental design was a RCB with 4 replicates. Each plot consisted of a single row, 40 ft long with a 30-inch row spacing. Plots were artificially infested with black-head stage ECB egg masses. The egg masses were deposited on wax paper discs, precounted in the laboratory and placed in the whorl of the infested plants on 30 Jun and 9 Jul. Crop growth stage was 37 and 57 inches extend

Abstract Four conventional insecticides and a single formulation of Bacillus thuringiensis were evaluated for efficacy against ECB and CEW. Sweet corn was planted 3 Jul at the University of Illinois Vegetable Crops Farm, Champaign. Plant spacing was 30 inches with 26,100 plants per acre. Plots consisted of 2 rows × 50 ft, with 25-ft alley ways between each replication. The design was a complete randomized block with 4 replications. Insecticide applications were made to the 2 middle rows of each plot. Applications were made on 28 and 31 Aug and 3, 6, and 9 Sep (corresponding to 1, 3, 6, 9, and

Research focused on alternative methods to control Western flower thrips (Frankliniella occidentalis Pergande), encompassing chemicals from varying classes, parasitic nematodes, microbial insecticides, and physical/mechanical deterrents. Chemical spray applications were applied weekly for 4 to 6 weeks. Experiment 1 made comparisons between fenoxycarb (Precision), bifenthrin (Talstar), and entomopathogenic nematodes (Biosafe). Experiment 2 compared abamectin (Avid), spinosyn A and D (Spinosad), azadirachtin (neem extract: Margosan-O), and diatomaceous earth (a physical control aimed at deterrin

Abstract:
It is well known that modern agriculture would not be able to meet the current demand for food without the help of pesticides. However, conventional pesticides have been proven to be extremely harmful to the environment, to the species they are applied to, and, ultimately, to humans. As a result, bio-pesticides have been introduced in recent years and include natural substances that control pests, such as biochemical pesticides, microorganisms used as pest control agents (microbial pesticides), and pesticide substances produced by plants containing added genetic material, known as plant-incorp

Various stem borer species have been considered threats to rice production in Africa causing considerable yield losses depending on the type of stem borer species damaging the crop. The use of synthetic insecticides has been reported to be effective against stem borer problems but misuse and abuse make it unsuccessfully in the control of these stem borer species. Insect pest control has changed for a long time from using chemicals to natural control methods. Such natural methods include the use of microbial insecticides, <em>e.g.</em> Entomo-pathogenic fungi, Entomo-pathogenic bacteria, Entomo

The functional and structural features of microbial load in soil are influenced by the presence of insecticides. This study examined the impact of two organophosphorus insecticides, dimethoate and parathion on the microbial load of soil. The colony count of fungi, actinomycetes, bacteria, and nitrogen fixing bacteria was reduced after insecticides application at 7 and 14 days, but at 28 days the colony count began to increase. The growth of two white rot fungi including Pleurotus sajor-caju and Phanerochaete chrysosporium was affected by parathion, which was reflected by a decrease in colony r

The interaction of two crystal proteins, Cry1Ac and Cry1Jb was evaluated against cotton bollworm (Helicoverpa armigera). The 50% lethal concentrations (LC50s) were estimated to be 2.29 ng/ml and 6 039 ng/ml for Cry1Ac and Cry1Jb, respectively. When mixtures of these toxins in different proportion were assayed, the expected LC50s were lower than the observed LC50s, indicating a clear antagonism between the two toxins. Ligand blotting showed that both the toxins bind to 110kDa APN corroborating the results. This is the first report of antagonism of Cry1Jb with Cry1Ac toxin against cotton bollwor

Abstract:
Injury and control costs for the invasive scarab Japanese beetle (Family Scarabeidae, Popillla japonica) alone is estimated at $450 million per year in the U.S. Chemical controls are commonly used to control scarab pests, but concerns about human safety and negative impacts on beneficial and non-target organisms, such as pollinators, are increasingly driving the market towards less toxic and more environmentally friendly management options. Microbial entomopathogens are excellent candidates for biopesticides and biocontrol agents. Although microbial pesticides currently make up only 1–2% of th

Abstract:
The whitefly is among the main pests of crops, especially solanaceous and cucurbitaceous plants. The massive use of pesticides for its control has led to an increase in the pest’s resistance to different groups of insecticides and to environmental contamination. The use of biopesticides for its control is a sustainable alternative for the environment. The objective of this study was to evaluate the efficiency of two biopesticides based on entomopathogenic fungi against eggs, nymphs, and adults of whitefly in eggplant in a greenhouse.
