Abstract. Tarno H, Setiawan Y, Rahardjo BT, Wang J. 2021. Evaluation of the  ambrosia beetles traps on Pterocarpus indicus in Indonesia. Biodiversitas 22: 1332-1339. Angsana, Pterocarpus indicus Willd., is a native tree of Southeast Asia. This tree is commonly planted in large numbers as an ornamental or shade plant along the roads, in parks, and in residential areas in Malang and Batu Cities of Indonesia. Ambrosia beetles Euplatypus parallelus (F.) and Treptoplatypus micrurus (Schedl.) have been reported to attack P. indicus trees in Malang and Batu Cities. Therefore, effective traps are required for early detection and monitoring of the spread of ambrosia beetles. This research aimed to evaluate the effectiveness of different traps and to investigate the diversity of ambrosia beetles on P. indicus trees in Malang and Batu Cities. This research was conducted along the roads in Malang and Batu Cities using four types of traps: funnel trap, window flight trap, bottle trap, and yellow sticky trap. Eleven ambrosia beetle species were collected in this research. The most abundant species were E. parallelus and Cryphalus laticollis (Browne). The funnel trap was the most effective for capturing ambrosia beetles, whereas the bottle trap was the least effective trap. The funnel trap captured more E. parallelus and C. laticollis individuals than other traps. The ambrosia beetles captured using different traps were categorized as having low diversity. The ambrosia beetles collected from Malang and Batu Cities were categorized as having moderate diversity.

AbstractThe multiple funnel trap, an efficient, collapsible, non-sticky trap for scolytid beetles, consists of a series of vertically aligned funnels with a collecting jar at the bottom. The trap compared favorably with sticky traps and Scandinavian drainpipe traps for three species of ambrosia beetles and the mountain pine beetle. Minimum maintenance required for this trap allows for high efficiency in pheromone-based research, survey, and mass trapping of scolytid beetles.

Aulacaspis Tegalensis

By means of sticky traps and a suction trap, it was demonstrated on a plot of sugar-cane at Kawanda Research Station, Uganda, that large numbers of crawlers of Aulacaspis tegalensis (Zhnt.) become airborne (up to 10/m3). The numbers increase with wind speed up to about 2·0 m/s and then remain constant, but are depressed by increasing humidity. In laboratory experiments, crawler survival was reduced by high temperatures (30°C) and low humidities (30% r.h.), but some individuals should survive the extreme conditions sometimes experienced if airborne from morning until evening. On hatching, crawlers move upwards and towards the light, but downwards in the dark; movement is inhibited by high humidity. These behaviour responses indicate hat the presence of crawlers in the air is not accidental but a dispersal mechanism. At Arusha Chini, an isolated sugar estate in Tanzania, sticky-trap catches downwind of a windbreak confirmed that airborne dispersal of crawlers is a major source of infestation. It is shown that air currents could have carried crawlers to Arusha Chini from a source on the Kenya coast, 260 km to the east.

Abstract Honey bees are very valuable to human. These social insects contribute in the pollination of many crops. Also, the products from honey bee colonies have many nutritional and medicinal benefits. Thus, keeping honey bees are very valuable and can be considered as source of income to many families. There are many diseases and pests that attack honey bee colonies. The pests attack bee colonies include: hornets, wax moths, bee-eater birds, and beetles. Such challenges can impact the survival and productivity of honey bee colonies. In this study, some beetle species belong to Fam. Nitidulidae, Dermestidae and Mycetophagidae were detected in honey bee colonies in Egypt, during spring. Despite the presence of many beetle species in the agricultural environment, only few species preferred the invasion of the colonies for feeding. These beetles do not attack stages of honey bees. They only feed on stored pollen or bee bread, especially those fallen on the bottom of the beehives. This is an alarm to follow the feeding behavior and distribution of these beetles. These beetles’ species can be considered as potential pests to weak honey bee colonies, housed in old or damaged beehives. The presence of large numbers of these beetles in weak colonies may disturb the activities of the bees and may passively impact the survival of the colonies. Listing these beetles is very important to better understanding the interaction between honey bees and beetles. On the other side, small hive beetles were not detected in the colonies. These beetles are currently one of the major problems facing honey bees in different parts of the world. This study confirms the absence of small hive beetles from Egypt.

Potato psyllids vector ‘Candidatus Liberibacter solanacearum’ (Lso), the putative causal agent of potato zebra chip (ZC). Currently, sticky traps are the primary psyllid monitoring tools used by growers for making management decisions. However, the reliability of sticky traps in predicting psyllid numbers in potato fields has always been questioned. In 2013 and 2014, experiments were conducted in covered field plots at the Texas A&M AgriLife Research Station at Bushland to investigate the relationships among initial psyllid numbers, psyllids captured on sticky traps and their Lso status, and zebra chip incidence. Three densities of Lso-positive psyllids (5, 15, or 30/cage) were released under 2-week-old potato canopies with four replications in plot sizes of 7.6 to 9 m by 5 rows. Psyllids were released under the first plant in the center row and monitored weekly with a yellow sticky trap from the opposite end. Number of plants with zebra chip symptoms also was counted weekly beginning one month after infestation with psyllids. The total number of psyllids captured on sticky traps and disease incidence levels generally corresponded to the levels of psyllid density treatments (5 < 15 < 30), but the differences became more apparent toward the end of the experiments. Psyllid numbers in the different density treatments fluctuated more or less in synchrony over time, which appeared to reflect periodic emergence of new generations of psyllids. Initially, all captured psyllids tested positive for Lso. However, the proportions of psyllids testing positive declined dramatically after a few weeks, which suggested that the new generations of psyllids were devoid of Lso. Over all, less than 50% of captured psyllids tested positive for the pathogen. The decline in proportions of psyllids testing positive for Lso following successive generations has significant relevance to field situations and may partly explain why there are generally low percentages of Lso-positive psyllids under field conditions.

Set Up

The sampling sites, including roadsides and residential areas, were set up to collect ambient air and determine the volatile organic species it contained. For the roadside air, the average VOCs (volatile organic compounds) abundant at rush hour periods was two times that at non-rush hour periods. In the residential area, the VOC concentrationswere106 and 129 ppb during rush hour periods. The VOC concentration ratios of roadside and residential areas were in the range of 1.08–1.75 and the traffic emissions were related to the VOCs abundant in air. The highest VOC concentration was 168 ppb at midnight at residential sites and the VOC abundance could be two times that of roadside sites. This level of concentration could be attributed to the application of solvents and to human activity in a nearby motorcycle/vehicle maintenance plant, laundry rooms, etc. High abundant species were similar in both the roadside and residential air samples. These highly abundant species included toluene, acetone, acetonitrile, m,p-xylene and n-pentane, all of which can be emitted from traffic exhaust. Benzene, acrolein, formaldehyde, vinyl chloride and 1,3-butadiene were the main species with health impacts collected at both sites. In the micro-scale environment, the residential ambient air was affected by traffic flow from morning to night. In the midnight period, some local activities (a motorcycle/vehicle maintenance shop and laundry shops) affected the concentrations of certain VOCs (acetonitrile, toluene, hexane, 2-methylpentane, methyl cyclopentane and 3-methylpentane). The traffic and motor vehicles’ effects were determined, which could be useful for air quality management and strategy development in an urban area.

Many bark and ambrosia beetle species (Coleoptera: Scolytinae and Platypodinae) are known to have spread worldwide in relation to international trade. Concerns have been expressed within the European and Mediterranean Plant Protection Organization (EPPO) about recent introductions of non-indigenous species of these groups. Regulation of the non-coniferous wood trade into many EPPO member countries is currently not sufficient to cover such risks. In 2018–2019, an EPPO study on the risk of bark and ambrosia beetles associated with imported non-coniferous wood was carried out, and the key characteristics contributing to the pest risk from introduced species were determined using expert consensus. This paper summarizes the key findings of the study, which are available in full detail on the EPPO website. The study identified biological and other risk factors and illustrated them with examples from 26 beetle species or groups of species known to be invasive or posing a threat to plant health. These representative species were classified into three categories based on known damage and level of uncertainty. In the present article, factorial discriminant analyses were used to identify features of bark and ambrosia beetle biology associated with damage caused and invasiveness. Based on the information assembled and consideration of the risk factors, it was recommended that in order to prevent the introduction of new bark and ambrosia beetles via non-coniferous wood commodities, horizontal phytosanitary measures should be adopted, irrespective of the host plant species and the origin (i.e., for all genera of non-coniferous woody plants and from all origins). Phytosanitary measures are presented here for various wood commodities.

Nitidulid Beetles

Beetles in the family Nitidulidae can transmit the oak wilt fungus, Ceratocystis fagacearum, to fresh wounds on healthy oak trees, leading to infection and disease development. Historically, nitidulid beetles have not been considered important vectors of the pathogen in Missouri. Studies were conducted in the spring of 2005 and 2006 to determine frequencies of nitidulid beetle species contaminated with C. fagacearum visiting fresh wounds on red oak trees in central Missouri. Colopterus truncatus, C. niger, and C. semitectus were the most abundant species collected from fresh wounds and the only species found to be contaminated with Ceratocystis fagacearum. Of 230 beetles assayed for C. fagacearum, 23 yielded the fungus. Contamination frequencies were higher for beetles collected in April than May; no beetles collected in June were contaminated. We hypothesize that Colopterus truncatus, C. niger, and C. semitectus are principal nitidulid beetle vector species in Missouri during spring. The risk for pathogen transmission by these beetles appears to be greatest in April and least in June.

Pheromone-baited traps are frequently used for research or in monitoring populations of bark beetles such as the southern pine beetle, Dendroctonus frontalis Zimmermann, and Ips spp. which are important pests of southern pines. We compared the effectiveness of two commercially available trap designs, the multiple-funnel trap and the slot trap, for collection of D. frontalis, three species of Ips, and two of their common predators. Slot traps captured greater numbers of bark beetles while multiple-funnel traps captured more predators. Multiple-funnel traps were judged to be easier to transport and check in the field. This study indicates that slot traps are preferable for monitoring southern bark beetles with the least disruption to natural enemy populations, while multiple-funnel traps are better for monitoring bark beetle/predator ratios. Due to ease of checking and handling, multiple-funnel traps are preferable for uses that involve large numbers of traps, long-distance manual hauling, or frequent relocation of traps.

AbstractParasitoids of Aonidiella aurantii (Maskell) on citrus in South Africa were monitored using two types of yellow sticky trap. One of these traps was highly efficient, being fluorescent with peak reflectance at about 530 nm. Aphytis spp. populations were low before February and high thereafter. Citrus surrounded by natural bush was an isolated reservoir of high host and parasitoid population levels. Aphytis spatial distribution within the orchard was extremely patchy, with over 100-fold differences in population levels over a distance of a few metres. This patchiness mirrored that of its host. This contagious spatial pattern was maintained despite 1000-fold seasonal changes in population levels. These temporal changes were characteristic and general throughout an orchard, and independent of patchiness. Initial Aphytis population levels did not dictate the final population level at the end of the season. Comperiella bifasciata Howard and its hyperparasitoid Marietta javensis (Howard) also showed clear seasonal population trends, but not of the same magnitude as those of Aphytis. There was no statistically significant correlation between the spatial distribution of one parasitoid with that of another, even between C. bifasciata and M. javensis. The patchiness of these two species was not correlated with overall host density. Aphytis and C. bifasciata were partially mutually exclusive. Aphytis was by far the most economically important of the parasitoids. Pest management practices, therefore, should aim at conserving the pool of Aphytis within the orchard as far as practicable.
