A study was made of some aspects to be considered in experiments for the control of codling moth in apples. Examination of the number of fruit damaged by either deep entries or stings in samples of 100 fruit showed that the counts of damaged fruit could be considered as random samples from a Poisson (or binomial) distribution both within trees and also in plots up to a size of four test trees. An optimum plot size and sampling procedure was determined in experiments for the control of codling moth in apples. A single-tree plot with four samples per tree is optimum for unguarded plots, and plots of either one, two, three, or four trees with four samples per tree are satisfactory for guarded plots where the trees are hand-sprayed. Guarding seems an unnecessary safeguard and expense for hand-sprayed plots. Where "Air-Blast" spray machines are used, large plots with a double guard row are necessary, and it is sufficient to examine two to four samples per tree. It is suggested that Smith's heterogeneity law can be used to obtain the optimum plot size in experiments for the control of insect pests, and possibly of diseases on fruit trees. No reduction in experimental error was obtained by using the crop size of individual trees as a covariate in an analysis of covariance.

The study area included 127 species of parasites from the Tachininae subfamily (Diptera: Tachinidae) belonging to 53 genera and 14 tribes. The study was conducted in 2008-2018 in Primorsky Territory. Presently the list of tachinid fl ies with known hosts is made up of 52 species (40.9% of the total number). The Tachininae parasitize insect orders of Lepidoptera (86.6% of the total number of species with known data), Coleoptera (9.6%), Diptera (1.9%), Dermaptera (1.9%). Among representatives of Lepidoptera, species of Noctuidae (34.1%), Lymantriidae (10.7%) and Tortricidae (9.2%) families prevail. During the study, 28 host species of tachinids fl ies were revealed in the Lepidoptera order which are pests of agricultural crops, park, garden and forest vegetation. These insects, in the larval stage, feed on leaves, flower buds, flowers and fruits of trees and shrubs. They also damage fruit trees, park plants, sown seedlings, grain crops, basal parts and stems of vegetables. In the order of Coleoptera, Scarabaeidae family, 3 species are classifi ed as pests.It is for the fi rst time that the information was given on parasitizing of Тachina fera L. in caterpillars Spodoptera exigua Hbn. (Lepidoptera: Noctuidae), Parhamaxia discalis Mesn. in imago Holotrichia parallela Motsch. (Coleoptera: Scarabaeidae), Hamaxia incongrua Walk. in imago Gametis jucunda (Fald.) and Anomala luculenta Er. (Coleoptera: Scarabaeidae), Mikia tepens Walk. in caterpillars Lymantria dispar L. (Lepidoptera: Lymantriidae). The study of the fauna of Tachinidae and trophic relations in the larval stage is of great scientifi c and practical importance in the fi ght against insect pests of agriculture and forestry.

The value of woodpeckers in insect control has been recognized by entomologists for many years. Woodpeckers seek out and destroy many of the hidden insect pests of forest, shade and fruit trees and in the stalks or stems of agricultural crops. In forest trees, these birds have been reported destroying buprestid larvae and prepupae (1, 4, 16), cerambycid larvae and pupae (9, 10), and scolytid beetles (11-15, 18).

“BugMap” is a citizen science mobile application that provides a platform for amateur and expert scientists to report sightings of two invasive insect pests, the tiger mosquito Aedes albopictus Skuse (Diptera: Culicidae) and the brown marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae). The latter is a notorious pest of fruit trees, vegetables, ornamentals, and row crops, inflicting severe agricultural and ecological disturbances in invaded areas. Our approach consists of coupling traditional monitoring with citizen science to uncover H. halys invasion in Trentino. The project was initiated in 2016 and the first results were reported in 2018. Here, we revisit our initiative four years after its adoption and unravel new information related to the invader dispersal and overwintering capacity. We found that our previous model predicted the current distribution of H. halys in Trentino with an accuracy of 72.5%. A new MaxEnt model was generated by pooling all reports received so far, providing a clearer perspective on areas at risk of stink bug establishment in this north Italian region. The information herein presented is of immediate importance for enhancing monitoring strategies of this pest and for refining its integrated management tactics.

Phytophagous stink bugs (Hemiptera, Pentatomidae) are economically important insect pests of fruit, vegetable, nut and field crops. This study was carried out during the season of 2013 in orchards within Erbil city, to follow the stink bug Mustha spinulosa (Lefebvre, 1831) seasonal fluctuation on some fruit trees: olive, plum, apricot, pear, apple and almond. The stink bug reaches its maximum abundance throughout the second week of August (38.2/tree) coinciding with mean temperature and relative humidity of 33.40°C and 28.14% respectively, and the highest total mean of the number of the insect was recorded on the olive trees (181.8/tree). The study reveals that the stink bug attacked 22 trees (fruit and forest) while it has not attack any herbal plant.

The cupuassu (Theobroma grandiflorum (Willd ex Sprengel) K. Schum.) is a native tree from the tropical rainforest and one of the most important fruit trees in the Amazon region. Its pulp and seeds are widely used in the alimentary industry, as well as food by the people of northern Brazil. Among the factors that can compromise the production of cupuassu are the attack of diseases and insect pests. The aim of this work is to report the attack of a wood-borer lepidopteran in commercial cupuassu plantation located in the district of Nova Califórnia, Rondônia State, Brazil. In April 2019 an infestation of a wood-borer insect was observed causing the death of branches. Branches containing caterpillars in their inside were collected and taken to the Entomology Laboratory of the Embrapa Acre, where they were placed in a screened cage. After about 60 days, an adult insect emerged, which was identified as Magulacra nigripennata, a lepidopteran associated with cocoa and cupuassu plantations in that country. A random survey of 100 plants in the plantation area detected an infestation level of 36%, indicating the harmful potential of this pest to the cupuassu crops in the Amazon region.

The following paper deals with insect pests of various minor crops and fruit trees in the Colony of Mauritius. The damage caused by most of the pests dealt with is often not very apparent, as many of these crops are not grown extensively, and have not been the object of any special investigation up to the present. If extensive cultivation of any of these should be undertaken, it is clear that there might be created a new environment favourable to increase of the insects, and that the pest problem would then have to be dealt with seriously. Our knowledge of these pests is very deficient, as their life-history and habits have never been studied in detail locally. It is also quite probable that extended cultivation may bring to light many potential pests which at present escape our attention.
