“…Nowadays, chemical nematicide are losing their popularity among farmers for protecting their crops from nematode infestations because of their harmful effects and environmental pollution that led to an urgent need for safe and more effective options. Biological control promises to be such an option (Radwan and Farrag 2012;Saad et al 2019). Recently, one of the biological control practices attempted is the study of suppression effects of cyanobacteria (blue-green algae) on the plant-parasitic nematodes.…”

The nematicidal effect of three marine algal, Ulva fasciata Delile (UF) (green algae), Corallina mediterranea, Corallina officinalis (red algae), extracts on egg hatching and second-stage juveniles (J 2 ) mortality of root-knot nematode (Meloidogyne incognita) in vitro compared to the nematicide activity of Oxamyl 24% SL (5 ml/l) was investigated. Results revealed that all treatments at the applied concentrations suppressed the egg hatching in 3 days. In details, the algal strain Ulva fasciata Delile extract showed the highest activity in decreasing the eggs hatchability after 3 days with 87%. Consequently, all treatments significantly increased the mortality of J 2 larvae after 12, 24, and 48 h compared to the control treated with distilled water. Under greenhouse conditions, all treatments in inoculated soils cultivated with tomato plants had reduced numbers of galls, egg-masses/plant, and the number of J 2 /250 g than the non-inoculated soil. The algal extract and the Oxamyl 24% SL (5 ml/l) increased the length and fresh weight of plant shoots and roots than the untreated. However, there were no differences in shoots and roots fresh weights and their lengths in the plant treated with Oxamyl 24% SL (5 ml/l) or the extracts of U. fasciata and Corallina officinalis. These results were closely similar to control. Both of peroxidase and polyphenol enzymes activity for the control plants remained relatively stable, while the activity of the two enzymes in the plant inoculated with the nematode decreased during 2 to 18 day post inoculation (dpi). These activities increased in inoculated plants treated with C. officinalis, C. mediterranea, and U. fasciata extracts and the other plants treated with Oxamyl 24% SL (5 ml/l). The maximum activity of the three enzymes was recorded at 5 dpi after treatment with U. fasciata.

“…All treatments of the tested fungi showed a very weak effect against S. littoralis 2 nd instar larvae. However, dissimilar endophytic fungi effect against an insect may be based on the degree of pest specialism or could be due to the technique of the treatment (Gange et al, 2012;Saad et al, 2019). Several studies showed that the artificial inoculation of plants with entomopathogenic fungi provided them with resistance to pests in addition to the growth-promoting effects of these fungi (Vega, 2018;Mantzoukas and Eliopoulos, 2020).…”

The means of biological control methods in which entomopathogens are being applied to crops has been adopted for several years. However, endophytic entomopathogenic fungi could provide plants with a longer protective effect compared to usual bio-control agents' applications since they are being internally associated with plants and could grant them more sustainable protection. This study was an attempt to isolate the endophytic fungi from Hytech 2031, Pioneer 3444 and SC 132 maize hybrids and investigating their pathogenicity against Sesamia cretica, Pectinophora gossypiella and Spodoptera littoralis in different larval instars. Five fungi were isolated from the maize hybrids, i.e. Aspergillus flavus MRDS 301, Curvularia lunata MRDS 302, Chaetomium madrasense MRDS 303, Alternaria alternate MRDS 304 and Aspergillus flavus MRDS 305. C. lunata MRDS 302 and C. madrasense MRDS 303 treatments showed insecticidal effect (100 %) against S. cretica 1st instar larvae. All treatments against S. cretica significantly reduced the weight of the resulting full-grown instar larvae. C. madrasense caused the highest mortality to P. gossipiella 1st instar larvae compared to other treatments. In general, A. flavus MRDS 305 was more effective than A. flavus MRDS 301 against all the tested pests. Soil infestation was a highly effective method of inoculation to introduce the fungus C. madrasense inside maize plants since the fungus was isolated from both roots and leaves.

“…More recently, Saad et al (2019) tested the effectiveness of spore suspension of some endophytic fungi for their pathogenicity to the larvae of the cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) and found that Alternaria alternata caused 33.3% mortality.…”

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.Not for reproduction, distribution or commercial use. ABSTRACT Article HistoryA total of 26 fungal strains were isolated from aphids and tomato leaf miner as indigenous species and from red palm weevil and peach fruit fly as an invasive insect. Fungal strains tested for their abilities to attack both bean and wheat aphids. The mortality of aphids due to these fungi was estimated. Results showed that eight entomopathogenic fungi Scopulariopsis brevicaulis, Verticillium sp., Fusarium chlamydosporum, Fusarium proliferatum, Fusarium semitectum, Pochonia chlamydosporia var. catenulata, Fusarium solani and Fusarium verticillioides exhibited high virulence 60-100%. However, Scopulariopsis brevicaulis, Verticillium sp., Fusarium chlamydosporum and Fusarium solani proved to be the most virulent species against the target aphids inducing 90%-100% mortality.
