The study was carried out to study the effect of the infestation by Myzus persicae (Sulzer) (Hemiptera: Aphididae) and Tetranychus urticae Koch (Acari: Tetranychidae) on the internal components of Aloe barbadensis (Miller), the common name Aloe Vera cactus which belong to (Fam. Liliaceae). Experiments were carried out at two locations (governorates), Al- Orman garden (Giza Governorate) and The international garden (Alexandria Governorate) during season 2021. Obtained results showed that the infestation by M. persicae and T. urticae reduced the concentration of the internal components of Aloe Vera leaves such as Vitamin A, Vitamin C, Vitamin E, Vitamin B12, Folic acid, Amino acids, Salicylic acids, Minerals, Sugars, Lignin, Saponins and Beta carotene. And obtained results showed also that the effect of the infestation by M. persicae was higher than the effect of the infestation by T. urticae compared to control (Aloe Vera plants which did not infest by any pests) at the two tested locations. Statistical analysis showed that were highly significant differences between concentrations of the internal components of the infested Aloe Vera cactus plants with the two tested pests compared to the concentration of the same components in the control (non-infested cactus plants).

This study was carried out to study the effect of the insect infestation by The Green Peach Aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) and The Greenhouse Whitefly, Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae) on the quantity of the annual production of the strawberry crop, Fragaria ananassa (L.). This study was carried out at Tokh region (Qaliobya Governorate) during two successive seasons 2020, 2021 under glasshouse conditions. This study was divided into three parts, first part studied the population fluctuation of M. persicae and T. vaporariorum on strawberry plants during the two successive seasons, second part studied the effect of insect infestation by the two insects on the quantity of the annual production of strawberry fruits at the two successive seasons compared to control (which did not infest with any insect) and third part studied the effect of insect infestation by the two insects on the internal components of strawberry fruits. Results obtained showed that the infestation by M. persicae and T. vaporariorum reduced the quantity of annual production of strawberry fruits compared to control (which was non-infested by the same insects). Also, results obtained showed that the infestation by the same insects reduced both total sugar and total protein on strawberry fruits compared to control. [ABSTRACT FROM AUTHOR]

The present taxonomic revision of the family Malachidae (Genera: Attalus, attalusinus, brachyattalus, Callotroglops, Cephalonicus, Clanoptilus, Ebaeus and Hypebaeinais basedmainly on the materials, represented in the main reference insect collections in Egypt and/or materials collected during the field survey. Diagnostic characters of the genera and species based on the external morphological characters of the adults. Synonyms, taxonomical notes, local and world distribution of each species are provided.

A checklist of the family Megachilidaeas existing in Egypt is given, based on material kept in the main reference insect collections in Egypt and records in the literature. The list includes 102 species and 6 subspecies belonging to 9 genera of 5 tribes (Anthidini, Fidelini, Lithorgini, Megachilini, and Osmini) under two subfamilies (Fidelinae and Megachilinae), of which 84 species of seven genera and the six subspecies are insect pollinators, and 18 species of two genera are cleptoparasities. Updated scientific names and synonyms are presented together with taxonomic notes on host records and distribution for most species in Egypt. All taxa (subfamilies, tribes, genera and species are alphabetically arranged. [ABSTRACT FROM AUTHOR]
