The current investigation was performed to assess the effectiveness of predators as biocontrol agent against Aphis craccivora and Myzus persicae on broad bean field. Aphis craccivora had three peaks of abundance during the fourth week of December, first week of February and March of 2020-202 season (632, 901 and 671 individuals / 25 leaves). While it had two peaks during the second week of January and February of 2021/2022 (914 and 1085individuals/25 leaves). Meanwhile, M. persicae had two peaks of abundance (498 and 542 individuals/25 leaves) in 2020-21 and three peaks (689, 608 and 434 individuals/25 leaves) in 2021-22. The common predators caught in the broad bean fields were: Coccinella undecimpunctata L., Chrysoperla carnea Steph., Cydonia vicina isis (Muls.) , Scymnus sp ., Metasyrphus corollae F. and Orius sp. These predators recorded two peaks (50 and 52 predators/ 25 leaves) during the first season, and three peaks during the second season (40, 44 and 39 predators / 25 leaves) on broad bean. Biology of C. carnea on Aphis craccivora and Myzus persicae were examined at 26 ± 1°C and 70 ± 5% R.H. The total developmental time of C. carnea (egg hatching to adult exclusion) was 18.59 ± 0.43 and 23.54 ± 0.55 days when fed on A. craccivora and M. persicae , respectively. The mean number of eggs per C. carnea female was 345.83 ± 5.11 and 489.0 ± 6.58 eggs females fed on A. craccivora and M. persicae during their larval stage, respectively.

Seven Egyptian wheat cultivars were crossed with Sr 2 (the stem rust resistant gene), and their parents, F 1 , F 2 crosses were tested to natural stem rust disease in the field of Gemmeiza Agricultural Station, ARC, during the 2019 to 2021 growing seasons. The Sr 2 gene was completely resistant to stem rust, while the Egyptian cultivars showed different responses to the disease. Sakha-95 was completely resistant, Misr-1 and Misr-2 showed high susceptibility. Gemmeiza-12, Giza-171, and Sakha-94 showed moderate resistance (MR), while a trace of moderate susceptibility (Tr-MS) was recorded for the cultivar Misr-3. All the F 1 crosses were resistant, indicating the dominance of resistance to stem rust disease. Chi-square goodness of fit was used to assess the independence of Sr 2 resistance gene in the tested cultivars and F2 crosses. The crosses Sr 2XGemmeiza-12, Sr 2X Sakha-94, Sr 2XSakha-95 and Sr 2XGiza-171 have the expected segregation ratio of 15:1 for a duplicate gene. However, the crosses Sr 2XMisr-1 and Sr 2XMisr-3 fit a 3:1 ratio conditioned by one dominant gene. The resistance of the cross Sr 2XMisr-2 fits complementary gene action (9:7). Three specific SSR markers (xgwm533, stm559tgag, and stm598cac) were used to identify Sr 2 in the Egyptian cultivars and their F1 populations. The three markers confirmed presence of Sr 2 gene in the Egyptian cultivars and their F1 populations. However, the stm598cac marker could differentiate between the tested cultivars and their F1 populations by amplifying an additional band with a molecular weight of 200bp. Molecular analysis confirmed the results of chi-square test and could be serving in developing wheat programs.

The effect of constant temperatures (23º, 27º, and 32±1ºC) on the development and life table of Spodoptera frugiperda that reared on the maize host plant was examined. The developmental times of all stages (eggs to adults) decreased linearly when temperature increased. The incubation period of the egg stage decreased significantly from 4.8 to 1.37 days when the temperature increased from 23° to 32±1°C. Temperature significantly affected on development of immature stages and subsequently the total generation time. The total immature duration lasted 47.07, 27.13, and 14.47 days at 23°, 27° and 32°C respectively. Temperature also significantly affected the life table estimates of S. frugiperda . The highest fecundity (717.67 eggs/♀), hatchability percent (94.29%), and net reproductive rate R 0 ; (85.38 females/female) of S. frugiperda were estimated at 27°C, whereas the highest intrinsic rate of natural increase r m , (1.18 times/female/day) and finite rate of increase e rm (1.20 times/female/day) of S. frugiperda were estimated at 32 °C.

The efficacy of six pesticides belonging to different chemical groups namely (Neomyl 90% SP, Agrinate 24% SL, Mesurol 2% RB, Metarol 5% EG, Biogard 6.5% WP and Cranch 10% Sp) against the glassy clover snail M. cartusiana with various concentration and applications under laboratory and field conditions. Results showed that, under laboratory conditions the cumulative mortality percentage increases with the increase in the time of exposure to the pesticide, as well as the concentration rate. Data revealed that, Neomyl, Agrinate, Metarol and Mesurol were the most effective while Cranch and Biogard were the lowest. Regarding field trial, results revealed that, the efficacy of ready pellet baits was increased when applied by hand sowing than in piles on plastic pieces as in Metarol and Mesroul. Conversely, Neomyl and Agrinate exhibited the highest reduction percentage when applied as poisonous bait (piles on plastic pieces) than spray application. In concerning to Crunch and Biogard they show weak efficacy whether applied by poisonous baits or spraying

This study was carried out to survey the main piercing–sucking insect species that infesting maize plants in Zagazig district, Sharkia Governorate, Egypt during 2020 and 2021 seasons, in addition to estimate the effects of potassium fertilization on populations of aphid, leafhopper and planthopper insects. Plant samples, sweeping net, yellow sticky broad traps were used to collect these piercing–sucking insects from different potassium fertilized maize plants. Results showed that aphid species that infesting maize plants were Rhopalosiphum maidis , R. padi , Aphis gossypii , the leafhoppers were Empoasca decipiens , E. decedens , Cicadellina chinai, C. bipunctella zea and Balclutha hortensis , and the planthoppers were Sogatella vibix and S. furcifera . Potassium fertilization of maize plants influenced the population density of the aforementioned homopterous insect species. The highest mean number of the aforementioned homopterous insect species occurred with F1 (zero potassium fertilization) treatment, while the lowest population density was recorded with F4 (150 kg. Potassium sulphate/feddan). Chemical analysis showed a reverse relationship between protein and carbohydrate contents and aphid, leafhopper and planthopper populations on all tested potassium fertilized maize plants, while a positive relationship between pH values and the aforementioned insect populations was obtained.

The comparative study of the female body structures of many species of Diaspididae has been done using Leica microsystems. Several types of sensilla were described for three species namely: Parlatoria zizyphii , Lepidosaphes ficus and Lepidosaphes beckii . Four thermo-hygro-sensory species as sensing organs for temperature and humidity, namely plachodea in lepidosaphes beckii , sensilla basiconica and styloconica in Parlatoria zizyphii , sensilla caeloconica in lepidosaphes ficus and tuft organ in lepidosaphes ficus ; One type of gustatory receptor is a styloconica in Parlatoria zizyphii ; infrared receptors (IR), also in Parlatoria zizyphii ; olfactory organs such as sensilla placodea in Parlatoria zizyphii. Measurements of sense organs in different species were done using ocular micrometer. Also, dimension measurements of each sensillum of temporary and permanent females mounts were done. According to these comparative studies, the general regulation of sensilla was assumed to be Diaspididae. Eight sensory phenotypes were identified, with an attempt to use these data at the systemic level. The results of this study provide an important basis for linking morphological characteristics of sensory organs to insect behavior and should stimulate the development of effective quasi-chemistry-based control strategies against species belonging to the
