“…At the same time, there are changes in the structure of pest populations in agrocenoses, increased development and harmfulness of phytophages, which previously had no economic importance. Thus, the scientific work of M. Arya and F. Farooq reports on the increase in the number and harmfulness of the woolly aphid (Eriosoma lanigerum Hausmann), which has acquired the status of a dominant species (Arya & Farooq, 2019).…”

The most widespread culture in the structure of fruit plantations in Ukraine is the apple tree. An important factor in the highly efficient production of apples is ensuring proper phytosanitary state of plantations and observing agrotechnological methods of growing, which is possible only with constant and long-term monitoring of the species composition, population dynamics, biological and ecological features of the entomoplex. The aim of the study conducted in 2005-2020 was to determine the ecological structure of the harmful entomocomplex of apple orchards under the conditions of the Central Forest-Steppe of Ukraine. Field, laboratory and chamber research methods generally accepted in ecology and entomology were used to fulfill the tasks. In the study, 52 species of phytophagous insects from 25 families and 7 orders were identified; 5 species of phytophagous mites from 3 families of Tetranychidae (Panonychus ulmi Koch., Tetranychus urticae Koch., Scizotetranychus pruni Oudms.), Bryobiidae (Bryobia redikorzevi Reck., syn: Bryobia praetiosa Koch.), Eriophyoidae (Eriophyes mali Nal.) were also found. The taxonomic structure of phytophagous insects was dominated by representatives of the orders of Lepidoptera (24 species), Coleoptera (14 species) and Homoptera (9 species), the portion of which collectively amounted to 90%. A range of Lepidoptera represented by 13 families was characterized by wide species diversity: Tortricidae, Gracillariіdae, Yponomeutidae, Lyonetiidae, Cossidae, Sesiidae, Coleophoridae, Lasiocampidae, Geometridae, Pieridae, Arctiidae, Noctuidae, Orgyidae, which accounted for 46% of the harmful entomocomplex. The most numerous (dominant) species for the period 2005-2020 were three species of aphids (Aphis pomi De G, Dysaphis devecta Walk, Dysaphis mali Ferr.), apple moth (Carpocapsa pomonella L.) and leaf rollers (Archips rosana L.). In terms of trophic specialization, polyphages dominated 75% (39 species) of apple tree agrocenoses, 10% (5 species) of oligophagous insects, 15% (8 species) -monophages. The life forms were dominated by phytophiles -dendrobiotes, the percentage of which in the total structure of insect pests was about 90%. The species composition of harmful entomofauna and ecologically constant species of phytophagous insects in apple plantations in the Central Forest-Steppe of Ukraine were specified. A promising study is to clarify the features of the biology of the most harmful phytophagous insects under the conditions of climate change and to develop environmentally safe means of protecting apple plantations from pests.

Plant diseases and pests are important factors determining plant yield production, including mango. Mango fruit rot caused by insects and microbes has become a significant threat to mango production in Southeast Asia and worldwide. Insect plant pathogens affect crop yields' profitability, quality, and quantity. Some infections could occur before harvest and remain dormant until the favourable condition is achieved, and the disease will break out after harvest, reducing mango production. They act as a threat to the crops through various mechanisms of pathogenesis that compromise the immune system of the plants, such as developing any ways to attack the plants, seeking entry via open pores or exposed surface or wound, and sourcing nutrients forcefully for their growth and development. Depending on the environmental factors, the insect contracts the host through primary or secondary infection. This paper summarizes mango fruit rot disease caused by insects groups such as fruit borers (Autocharis albizonalis and Citripestis eutraphera), fruit flies (Bactrocera dorsalis), and mango seed weevils (Sternochetus mangiferae). This review will provide information about fruit rot diseases on mangoes caused by insects, the mechanism of infection, the interaction between insect damage and fungal infections, effective control methods, and related integrated pest management approaches.
