Deudorix livia (Klug) (Lepidoptera: Lycaenidae) causes substantial
damage to pomegranate fruits, leading to significant yield losses. This
damage directly impacts the economic viability of pomegranate farming.
Studying the spatial distribution of D. livia and its predators is vital for
developing effective, sustainable, and environmentally soun...
Spiders are a significant predatory group across many agricultural crop systems. In Egypt, pomegranate is one of the most considerable fruit crops. Unfortunately, pomegranate fruits are attacked by a range of insect pests. These pests reduce the quality and marketing of pomegranate fruits. So, the present study focuses on identifying true spiders i...
The present study was initiated to validate whether the artificial or natural diets are the best for Galleria mellonella and Plodia interpunctella hosts for rearing Trichogramma turkestanica Meyer and to assess the effect of reared host eggs on the morpho-biological features of Trichogramma turkestanica and their suitability for parasitism.

The fall armyworm, Spodoptera frugiperda is one of the most highly invasive and damaging agricultural pests. In Egypt, maize grains have enormous economic importance. Infestations of S. frugiperda in maize cause a significant reduction in maize yield. This research aimed to assess the potential impact of LC50 values for chlorpyrifos, methomyl, and...
The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) is a major date palm pest. In this study, we aimed to isolate and identify the Serratia nematodiphila from RPW as potential biocontrol agents. We isolated the bacteria from infected RPW larvae and adults and identified using colony morphology characteristics, b...
Food security, mediated by agricultural pests, puts the world at stake. Fall armyworm (FAW), Spodoptera frugiperda, is an invasive polyphagous pest that recently made problems worse. The current study inspects the potency of spinetoram in FAW control programs. Spinetoram is a biocide derived from spinosyns created by soil bacteria, actinomycete Sac...
Deudorix livia (Klug, 1834) (Lepidoptera: Lycaenidae) is one of the most serious lepidopteran insect pests attacking pomegranate fruit around the world, including Egypt (Assiut Governorate, Upper Egypt). To create an effective program (IPM) to control such harmful pests, accurate identification of the pest morphology and genetic structure is essent...
Honeybees play a crucial role in plant pollination, agriculture's biodiversity, and environmental balance. This study was conducted for the first time in "the Golden Triangle Area". The objective was to identify the bee species that inhibited the Red Sea, focusing on the coast. The work was conducted through intensive and extensive visual observati...
The egg parasitoid Trichogramma was used in Qus, Qena Governorate, Egypt, to control lepidopteran sugarcane insect pests. The primary objective of this study was to identify the egg parasitoid, Trichogramma, by morphological and genetic approaches. Light microscope was used to examine the morphology of male and female adults and their measurements....
Green lacewing Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) has been recorded as an effective generalist predator, especially aphids. A study was carried out to determine the population fluctuations and dispersion of green lacewings and aphids inhabiting pomegranate orchards in Assiut, Northern Upper Egypt, during the 2021 and 2022 growi...
Article History The main goal of this study is to determine the species composition of the major cruciferous insect pests (phytophagous and entomophagous insects) inhabiting cabbage plantations in Assiut, Northern Upper Egypt during the 2017-2018 and 2018-2019 growing seasons. The abundance of the prevalent fungi species associated with the cabbage...
Mosquitoes are the key vector for the transmission of serious parasites and pathogens which affect many people worldwide. The massive overuse of synthetic mosquito insecticides had developed resistance in mosquitoes. Therefore, the need for reliable and eco-friendly control techniques became crucial. Nanoparticle fabrication is a cutting-edge and t...
This work was initiated for the first time to identify parasitoid species associated with the immature stages of Pieris rapae (L.) inhabiting cabbage plantations in Assiut governorate, Upper Egypt during the 2018 and 2019 cabbage growing seasons. Attacking periods and parasitism percentages (PPs) of the identified parasitoid species were calculated...
Article History cabbage growing seasons. Evaluation of the seasonal abundance of the cabbage aphid Brevicoryne brassicae L in cabbage fields and responsibility of certain biotic factors for managing populations of this insect pest was the cornerstone of this investigation. Cabbage aphid, B. brassicae was found to be active on cabbage plantations an...
Anecdotal data in the past have suggested that the effect of the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), on maize yield is greater under drought and the effect of drought is greater under rootworm infestations, but no field experiments have controlled both moisture and rootworm levels. Field studie...
The western corn rootworm, Diabrotica virgifera virgifera LeConte, is the most important insect of maize, Zea mays L., but knowledge of its interaction with water deficit on maize production is lacking. A series of greenhouse experiments using three infestation levels of the western corn rootworm, D. virgifera virgifera, under well-watered, moderat...
The effects of soil moisture on the interaction between maize and western corn rootworm are understudied for a pest of this magnitude. In 2012, a field study was conducted to evaluate the interactions of the western corn rootworm (WCR) Diabrotica virgifera virgifera LeConte and drought stress on maize. The experiment was a randomized complete block...
Drought can have a major effect on plant production and the western corn rootworm can exacerbate those effects. In order to quantify the interaction of western corn rootworm and drought, the growth rate of western corn rootworm and maize (B73xMo17) under three levels of both stressors was evaluated in greenhouse experiments. Significantly more west...
