The study was executed at apiary of Plant protection Dept. Fac. of Agric. Al-Azhar Univ., Cairo, Egypt, during two successive years 2019 and 2020 to determine the effectiveness of different seasons on the acceptance rates of the larvae and royal jelly production. In the first year, the highest acceptance means for Italian hybrid 72.1 and 65.43% for Carniolan hybrid were recorded at midspring on the other hand, the lowest acceptance percentages means were 50.86 and 55.8 % recorded at early summer for Carniolan and Italian hybrids respectively. Also, results demonstrated that mid spring gave the best mean weight of royal jelly per queen cell cup 238.35 mg. for Italian hybrid and 236.31 mg. for the Carniolan hybrid. The lowest quantity means were recorded in early summer 187.24 mg./cup for Carniolan hybrid and 198.74 mg./cup for Italian hybrid. In the second year, the highest acceptance means were 66.42 and 62.96% at mid spring for Italian and Carniolan hybrids respectively. Whereas the lowest acceptance percentage means were 44.44 and 48.4 % at early summer for Carniolan and Italian hybrids. Also, results cleared that mid-spring gave the best mean weight of royal jelly per queen cell cup, 229.71 mg. for Italian hybrid and 227.5 mg. for Carniolan hybrid. The lowest quantity means were recorded at early summer 186.72 mg./cup for Carniolan hybrid and 189.06 mg./cup for Italian hybrid. As for the effect of the bar level, the middle bar level gave the best results for royal jelly quantity and cup acceptance while the upper level gave the least royal jelly quantity and acceptance percentages in different seasons. There was a significant difference in acceptance percent and the royal jelly production per cup cell between mid-spring and early summer. Mid-spring gave the best results while the early summer gave the least results.
BeanAcanthoscelides Schilsky is the large genus of Neotropical bruchid beetles, in which most species show host plant specialization. The species of A. obtectus Say specialized on Phaseolus beans and therefore considered pests. Six legume grain species (Dried common bean, green common bean, lentil, cowpea, broad bean, and soybean) were selected to study the biology of this insect pest on these different legumes under the prevailing environmental conditions of 25 ± 2°C and 60 ± 10% RH. The results showed that an average number of eggs per mated female (fecundity) was recorded in common bean dried and green (26.33 and 22.66 eggs). While the fecundity decreased significantly to 10.00, 9.66 and 4.00 eggs/ female at Soybean, Broad bean and Lentil, respectively. The results also showed that there was a significant difference (p<0.05) in the percentage of emerged adults among the different legume hosts, namely dried common bean and Cowpea the highest value (88.00 and 76.65%) and lowest percentage (17.97%) of emerged adults in green common bean respectively, while no adults emerged in Soybean, Broad bean and Lentil hosts and the developmental periods of A. obtectus on different legume hosts and mean periods varies depending upon the different hosts.
The study aims to investigate the reliable identification members of the tribe Coccinellini, because of their potential as biological control agents, as predators of aphid insect pests, and other soft-bodied insects which, threatened the major crops. The surveys were conducted in twelve governorates represent the most geographical regions within, Egypt. Specimens were collected regularly during the years of 2017-2019, and some species have dispersed widely, and others are presented in one site. Totally, 9 species, subspecies, and more than 29 aberrations, belonging to two species Coccinella undecimpunctata, and Hippodamia variegata, classified into four genera within the tribe Coccinellini. Morphological characters especially the genitalia were studied with the morphometric measurements. Key to genera and species were constructed, and the illustration to the most effective characters were provided, with the local and world distributions for each species.
A chicklist of the family Anthicidae 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 74 species and 16 subspecies belonging to 17 genera under four subfamilies (Anthicinae, Notoxinae, Tomoderinae and Macratriinae). Updated scientific names and synonyms are presented together with Taxonomic notes. Certain subgenera were promoted to genus rank, consequently changing in scientific names. Activity period and distribution for most species in Egypt. All taxa (subfamilies, genera and species) are alphabetically arranged.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
