The moth, Hieroxestis subcervinella, Wlk., has recently become a pest of economic importance to the banana cultivators in the Canary Islands.Notes on the genus Hieroxestis and on the synonymy and distribution of the moth are included, and descriptions of the various stages of the insect are given. Details regarding the external morphology and chaetotaxy of the full-grown larva are enumerated, and setal maps showing the distribution of the setae have been added.The pupa is described in detail, and sex characters are noted.The economic importance of the pest is considered in its relation to its host-plants, while its method of attack and resulting injuries caused are discussed.The insect is considered as apodemic in the Canary Islands, and no parasitic natural enemies were encountered.

Iran is situated at the junctions of the Palaearctic and Oriental zoogeographical regions, and the Caspian, Baluchi and Irano-Tiranian floral zones, so it has a very diverse scale insect fauna. Scale insects (Hemiptera: Coccomorpha) are economically important in forestry, agriculture and horticulture. This taxonomic account of the armoured scales (Diaspididae) of Iran is the first of three works planned to cover all the scale insects in the country. It provides a resource for accurate laboratory identification of all the species known to occur in Iran or that are likely to be found there. Keys to the families of scale insects found in Iran, and to the 49 genera and 144 species of Diaspididae found there, are provided. Detailed line drawings of all the species known to occur in Iran are provided to facilitate identification. These are accompanied by detailed descriptions, distribution data, information on natural enemies, economic importance and host-plants recorded in Iran. The main purpose of the work is to provide agricultural entomologists concerned with pest control and quarantine inspection worldwide with a reliable means of species identification.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]

<p class="5abstrak"><em>Papilio</em><em> blumei</em> is an endemic butterfly of Sulawesi and especially in Bantimurung Bulusaraung National Park. This research was to observed of the behaviour and natural enemies of <em>P. blumei</em> in Bantimurung Bulusaraung National Park. The behaviour of the insect were mating, foraging, competiting, ovipositing and mud-puddling. Life table was used for analysis of mortality factors, therefore the number of mortality was analyzed by key-factors formulation. The result indicated that mating strategies is patrolling. Foraging activity of the sixth instar was the highest compared to the other instars and the lowest one activity of the prapupa stadium of <em>P. blumei</em>. Nectar host plants for the imago of butterfly were <em>Sarcosephalum latifolius</em> and <em>Eugenia sp</em>. There was <em>Scudderia sp</em>. as an interspesific competitor for larval <em>P. blumei</em>. The intraspesific competitor of the imago stage was male of <em>P. blumei</em>. Female <em>P. blumei</em> laid eggs on abaxial leaf <em>E.hupehensis</em> and the eggs hatched after six days. The larva of  <em>P. blumei</em> has a overheating behaviour and the adults has a mud puddling. The natural enemies of <em>P.blumei </em>is <em>Trichogramma</em> sp., with k value = 0.381, <em>Pteromalus </em>sp., with k value = 0.125 and <em>Formica </em>sp., with k value = 0.096.</p>

Preliminary Study

The cottony-cushion scale, Icerya purchasii Maskell, is one of the soft scales that attack a large variety of plants and trees in our Island. A series of host plants are listed and the insect is briefly described. Its distribution and natural enemies are also listed. Two insecticides, namely Parathion and Malathion, were tested for the control of the cottony-cushion scale in Australian pine, Casuarina equisetifolia Forst. Total control was obtained for all adult scales and crawlers with both insecticides, while in the checks both stages continued alive. It was found that the insecticides were not effective in the control of the eggs.

First Time

Life stages of Henosepilachna implicata (Mulsant), an economically important species of Epilachnini in India, are documented and illustrated. Mitochondrial DNA sequence data is provided for the first time for H. implicata with additional details on its host plants, distribution, and natural enemies. Its similarities and differences with other common pestiferous Henosepilachna spp. in India such as H. vigintioctopunctata (F.), H. septima (Dieke) and H. pusillanima (Mulsant) are discussed. Epilachna circularis Korschefsky, 1933 is found to be conspecific with H. implicata and is reduced to a junior synonym of the latter (new synonym). Notes are given on the distribution and natural enemies of some other species of Epilachnini of the Indian region.

Natural enemies of the gall maker Eugeniamyia dispar (Diptera: Cecidomyiidae) were studied on the urban area of Porto Alegre, RS, Brazil from October 1993 to March 1996. Galls and associated arthropods were followed weekly in the field on individual host plants (Eugenia uniflora, Myrtaceae) and also in the laboratory. Three species of ants attacked the galls, the most common being Pseudomyrmex sp. A proportion of galls was parasitised by Rileya sp. (Eurytomidae). The adults of this solitary ectoparasitoid were also attacked by the ants and fell prey to spider webs.
