Abstract Considered native to India, B. cucurbitae, the melon fly, is now found in more than 40 countries. The potential risk of its introduction to a new area is facilitated by an increase in international tourism and trade, and is influenced by changes in climate and land use. After introduction, it can easily disperse due to its high reproductive potential, high biotic potential (short life cycle of 3-5 weeks, up to 10 generations of offspring per year), and a rapid dispersal ability. The economic impacts of this species result primarily from the loss of export markets and the costly requirement of quarantine restrictions and eradication measures. Furthermore, its establishment has a serious impact on the environment following the initiation of chemical and/or biological control programmes. B. cucurbitae is of quarantine significance to EPPO (European and Mediterranean Plant Protection Organization), APPPC (Asia and Pacific Plant Protection Commission), COSAV (Comité de Sanidad Vegetal del Cono Sur), CPPC (Caribbean Plant Protection Commission), and OIRSA (Organismo Internacional Regional de Sanidad Agropecuaria) countries.

Abstract Native to South and South-East Asia, B. zonata is now found in more than 20 countries. The potential risk of its introduction to a new area is facilitated by increasing international tourism and trade, and is influenced by changes in climate and land use. After introduction, it can easily adapt and spread as it is a polyphagous species and has a high reproductive potential (as many as 564 eggs in a lifetime), high biotic potential (several generations of progeny in a year), and a rapid dispersal ability. B. zonata is a strong flier and can be active throughout the year. Economic impacts may result primarily from the loss of export markets and the costly requirement of quarantine restrictions and eradication measures. Furthermore, its establishment may have a serious impact on the environment following the initiation of chemical and/or biological control programmes. B. zonata is of quarantine significance to EPPO (the European and Mediterranean Plant Protection Organization) countries. The pest is classified on the A1 List of Pests recommended for regulation as quarantine pests.

Abstract Bactrocera dorsalis is a highly invasive species. Native to Asia, Oriental fruit fly is now found in at least 65 countries, including parts of America and Oceania, and most of continental Africa (sub-Saharan countries). The potential risk of its introduction to a new area is facilitated by increasing international tourism and trade, and is influenced by changes in climate and land use. After introduction, it can easily disperse as it has a high reproductive potential, high biotic potential (short life cycle, up to 10 generations of offspring per year depending on temperature), a rapid dispersal ability and a broad host range. The economic impact would result primarily from the loss of the export markets and the costly requirement of quarantine restrictions and eradication measures. Furthermore, its establishment would have a serious impact on the environment, following the initiation of chemical and/or biological control programmes. Invasive B. dorsalis has been shown to be highly competitive with native fruit flies where it has established, quickly becoming the dominant fruit fly pest (Duyck et al., 2004; Vargas et al., 2007; Vayssières et al., 2015). Oriental fruit fly is of quarantine significance to EPPO (European Plant Protection Organization), APPPC (Asia and Pacific Plant Protection Commission), COSAV (Comité de Sanidad Vegetal del Cono Sur), CPPC (Caribbean Plant Protection Commission), IAPSC (Inter-African Phytosanitary Council) and OIRSA (Organismo Internacional Regional de Sanidad Agropecuaria) countries.

Dacus Ciliatus

Abstract D. ciliatus is a major pest of a wide range of Cucurbitaceae in Africa, Asia and the Middle East. Adult flight and fruit transport are major means of dispersal. It may cause indirect economic impact on exports and could become a serious pest if introduced in the USA. It is an EPPO A1 quarantine pest within the category 'non-European Trypetidae' and is also of quarantine significance to CPPC (Caribbean Plant Protection Commission). Demographics, the main component of competition for fly species, have only been studied for this species by Vayssières et al. (2008). Compared to Bactrocera cucurbitae, it has longer egg incubation and immature stages, both disadvantages when competing for the same habitat. Preference for certain hosts allows D. ciliatus to enhance its biotic potential and maintain low population levels when competing with the melon fly, especially at low altitudes. D. ciliatus could colonize low temperature areas, as has been the case in Mediterranean areas. D. ciliatus seems less wiling to exploit new hosts compared to B. cucurbitae.

AbstractOne flowering specimen of Ophrys bertolonii (s. str.) — a plant with a Circum-Adriatic distribution and hitherto unknown in other regions — was found on 7th May 2010 in the vicinity of Kunadacs (Central Hungary; N 47°00′ E 19°17′). The nearest known populations of this Mediterranean plant inhabit the Adriatic coast (ca. 450 km away) in Croatia, therefore this new occurrence represents a significant long distance dispersal event. The circumstances of the occurrence argue against introduction, but we can not decide now whether this new appearance is temporary or permanent. The permanent establishment of this strictly entomophilous plant requires the presence of its specific pollinator in the close neighbourhood of the habitat. However, no pollination was observed on the three flowers of the plant until 9th May, and one day later the stem had disappeared most likely due to grazing. Whatever the long-term fate of the plant is, this discovery represents a significant long distance (jump) dispersal event, and testifies to the dispersal ability of Ophrys species. Additionally, the appearance of a mature Adriatic plant in Central Europe fits well into the currently observed, climate change driven northward expansion of European orchids, therefore this finding most likely reflects a growing Mediterranean-like climatic influence in the region.

Abstract Signed in 2009, the plant protection Commission Regulation EC No 1107/2009 created a new category of active substances, the low-risk substances, with specific status defined in Article 22. The initial and specific criteria, not suitable for microorganisms and natural substances, were modified in 2018, and the first low-risk substance, allocating Part D of Regulation EC No 540/2011, was granted in the same year. Since then, thirty-three low-risk substances have been granted with this specific status through approvals and renewals, while a larger list of potential low-risk substances from already-approved active substances was published. This list is only exploited during renewals, and this process would take another five years to complete. After four years of the implementation of this status, the number of such substances is still low, but is intended to increase slowly. Two more low-risk substances are already pending in 2021, which will bring the number of low-risk substances to thirty-five, while the initial list of potential low-risk substances (only renewals) included fifty-seven substances.

For Plant Protection and Quarantine (PPQ) and our partners, 2016 was a year of remarkable successes. Not only did we eradicate 10 fruit fly outbreaks, but we also achieved 4 years with zero detections of pink bollworm, moving us one step closer to eradicating this pest from all commercial cotton-growing areas of the continental United States. And when the U.S. corn industry faced the first-ever detection of bacterial leaf streak (Xanthomonas vasicular pv vasculorum), we devised a practical and scientific approach to manage the disease and protect valuable export markets. Our most significant domestic accomplishment this year, however, was achieving one of our agency’s top 10 goals: eliminating the European grapevine moth (EGVM) from the United States. On the world stage, PPQ helped U.S. agriculture thrive in the global market-place. We worked closely with our international trading partners to develop and promote science-based standards, helping to create a safe, fair, and predictable agricultural trade system that minimizes the spread of invasive plant pests and diseases. We reached critical plant health agreements and resolved plant health barriers to trade, which sustained and expanded U.S. export markets valued at more than $4 billion. And, we helped U.S. producers meet foreign market access requirements and certified the health of more than 650,000 exports, securing economic opportunities for U.S. products abroad. These successes underscore how PPQ is working every day to keep U.S. agriculture healthy and profitable.

The flight activity and flight muscle of the melon fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae) were observed. The Tethered technique was used to observe the flight activity in this study. The flight activity, and wing and flight muscles were compared between male and female melon flies. The results indicate that the female was relatively better and strong flier than the male. The mean duration of the flight activity of the females was 13.90 min/hour and of the males was 7.12 min./hour. The mean length, width, volume of wings of the males were 6.07 mm, 2.67 mm and 10.99 mm³, respectively. On the other hand, the mean length, width and volume of the wings of females were 7.07 mm, 2.87 mm and 15.60 mm³, respectively. In case of wing muscles, the mean volume of dorsal longitudinal muscle (DLM) in male and female was found 5.20 mm³ and 5.67 mm³, respectively. The mean length of flight wing muscle of male and female was 2.22 and 2.23 mm, respectively and the mean breadth of male and female was 1.65 and 1.77 mm, respectively. Dhaka Univ. J. Biol.
