Abstract

Numerous fruit fly species pose enormous threats to fruit and vegetable production worldwide, resulting in both quantitative and qualitative losses. The experiment evaluated the effectiveness of five different traps in a pumpkin (Cucurbita pepo) field located in Mahalaxmi municipality-6, Lalitpur district, Nepal, from April to June 2024. Yellow sticky trap, plastic bottle trap, bucket trap, steiner trap and plastic glass trap were used as treatments, provided with a cotton wick soaked in 0.5 ml of cue lure (except yellow sticky trap) placed at 1 m height on a standing stick in the pumpkin field. Throughout the collection, Zeugodacus cucurbitae was the most abundant, with a total of 1300 flies, followed by Zeugodacus tau, Bactrocera dorsalis, and Bactrocera nigrotibialis, respectively. In total, the highest average capture was led by the steiner trap, followed by the bucket trap, while the yellow sticky trap was the least effective. Laboratory rearing of fruit flies resulted in the emergence of a single species, Zeugodacus cucurbitae. Average pupal size was 5.67 ± 0.052 mm length, 2.15 ± 0.041 mm breadth, and weighed 14.90 ± 0.31 mg. Female adults were larger than males, measuring 7.59 ± 0.18 mm body length and 14.76 ± 0.31 mm wingspan, compared to males (6.98 ± 0.12 mm length and 14.65 ± 0.24 mm wingspan), and the ovipositor measured 1.75 ± 0.056 mm. This indicates a single species oviposits in a single fruit.

Abstract

Understanding the temporal dynamics of pollinator activity is critical for conserving ecological interactions in Mediterranean ecosystems, where resource scarcity intensifies during winter. This study examines diurnal and seasonal variations in bee visitation to Moricandia arvensis (Brassicaceae), a key winter-flowering species, and assesses the environmental factors influencing pollinator behavior. Over seven weeks (October–December 2023), bee visits were recorded three times daily (9:00 am, 12:00 pm, 3:00 pm) in Qena, Egypt, alongside measurements of temperature, humidity, wind speed, and atmospheric pressure. Results revealed pronounced diurnal patterns, with peak visitation at midday (12:00 pm: 21.40 ± 2.51 visits), significantly exceeding morning and afternoon rates (F = 176.32, p < 0.001). Seasonal activity declined sharply, dropping from 18.13 ± 0.51 visits/week in late October to 4.73 ± 0.20 by late November. Visitation correlated strongly with atmospheric pressure (r ≈ 0.99) and wind speed (r = 0.98–1), while temperature (r = -0.85 to -0.88) and humidity (r = -0.62 to -0.88) exhibited negative associations. Species-specific responses emerged: Andrena sp. foraged predominantly in mornings (27.00 ± 2.16 visits at 9:00 am), whereas squash bees (Peponapis spp.) peaked later (6.20 ± 1.17 visits at 12:00 pm). Pest pressures from Spilostethus pandurus and Lampides boeticus reduced floral viability, exacerbating seasonal declines. These findings underscore M. arvensis as a critical autumn resource for pollinators, bridging floral scarcity until winter. However, its utility diminishes under colder, humid conditions, highlighting vulnerability to climate shifts. Conservation strategies prioritizing arid-adapted flora, such as M. arvensis, in conjunction with integrated pest management, could enhance pollinator resilience in Mediterranean agroecosystems.

Abstract

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the major fruit crop pests in Morocco and the world. The braconid Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) is a larval-pupal endoparasitoid that can be used as a native biological control agent against this pest. In this study, several rearing parameters were controlled to optimize a profitable rearing strategy. density and quality of host larvae, 2) exposure time to parasitoids, and 3) sex ratio of parasitoids. To investigate the effect of each parameter, we concluded that the third instar of C. capitata in a proportion of 2:1 larva: female, exposed for 24h to parasitoids with a proportion of 1:1 and 2:1 female: male. These parameters demonstrate good performance, influenced by parasitism at approximately 80%, high flight ability at 88%, low pupal mortality, and high female progeny production. A diet of pure honey and water for parasitoid adults gives a high longevity of almost 70 days. Other parameters did not differ much throughout the trials. The results in our study can be used to provide a suitable protocol and environment for mass rearing of D. longicaudata as a biological control against C. capitata.

Abstract

Thrips, insects of the order Thysanoptera, play key roles as crop pests, pollinators across diverse plant families, predators of other arthropods, and contributors to forest ecosystem dynamics. Despite the high diversity of thrips in tropical regions, these areas remain insufficiently studied. A survey of thrips was conducted during the Tama Abu Scientific. A total of 46 species belonging to three families were collected. The majority (50%, or 23 species) of the collected species belonged to the family Thripidae.  Aoratothrips tenuis Priesner (subfamily Panchaetothripinae) and Elaphrothrips sensitivus Priesner (subfamily Idolothripinae) had not been previously recorded from Malaysia. An annotated list of Thysanoptera collected is provided. This list is by no means exhaustive, as it is based on a limited collecting period; many further species can certainly be expected from the Tama Abu Range and its adjacent areas.

Abstract

Termites are one of the organisms that have the potential to reduce oil palm productivity, so it is necessary to identify the species and map their distribution to support more effective and sustainable management. This study was conducted to identify termite species and map their distribution in oil palm plantations in Timpeh District, Dharmasraya Regency, Indonesia. This study used a survey method with purposive sampling based on several criteria, including the presence of plant attack symptoms, air humidity ≥ 60%, the presence of rotten wood, the presence of termite nests, and the sampling location was selected in oil palm plantation areas located on the edge of local roads at a distance of about 0-15 meters. The termite samples obtained were identified morphologically using a microscope and identification keys. Termite distribution mapping was performed using ArcGIS 10.8 software, while the relationship between termite presence and environmental factors (temperature, light intensity, and humidity) was analyzed using Redundancy Analysis (RDA). The results showed that there were six termite species in Timpeh Subdistrict, namely Macrotermes gilvus, Coptotermes curvignathus, Pericapritermes mohri, Dicuspiditermes nemorosus, Nasutitermes longinasus, and Termes propinquus. The species M. gilvus has the widest distribution throughout the subdistrict and is not significantly influenced by environmental factors, but rather by its high adaptability. Meanwhile, the other species have a more limited distribution and tend to be influenced by factors such as humidity, light intensity, and the availability of organic material. The mapping results provide a crucial basis for determining priority areas for control and termite management strategies in oil palm plantations, enabling more effective and efficient approaches to be implemented.
