Honey bees are constantly threatened due to the wide use of pesticides. This study presents the effects of deltamethrin on the mortality, olfactory learning, and memory formation of the native Saudi bee Apis mellifera jemenitica. Topical and oral application of realistic field and serial dilutions of deltamethrin (250, 125, 62.5, and 25 ppm) caused significant mortality at 4, 12, 24, and 48 h posttreatment. Bee mortality increased with the increasing concentration of insecticide at all tested posttreatment times. Highest mortality was observed at 24 h and 48 h after both exposure routes. Food consumption gradually decreased with increasing concentration of deltamethrin during oral exposure. The LC50 of deltamethrin was determined at 12, 24, and 48 h for topical (86.28 ppm, 36.16 ppm, and 29.19 ppm, respectively) and oral (35.77 ppm, 32.53 ppm, and 30.78 ppm, respectively) exposure. Oral exposure led to significantly higher bee mortality than topical exposure of deltamethrin at 4 h and 12 h, but both exposure routes were equally toxic to bees at 24 h and 48 h. The sublethal concentrations (LC10, LC20, and LC30) of deltamethrin significantly impaired the learning during conditioning trials, as well as the memory formation of bees at 2, 12, and 24 h after topical and oral exposure. Thus, deltamethrin inhibits learning, and bees were unable to memorize the learned task.

“…These compounds have sublethal, and lethal effects on honey bees depending upon the type of chemical, exposure dose, exposure route, simultaneous toxicity by other pollutants, honey bee lifecycle stage, type of bees, and the environmental conditions [45,76,77]. Anwar et al [78] investigated the 48-hour exposure toxicity of various insecticides on the Pakistani dwarf honey bee. They observed that emamectin benzoate exhibited the highest toxicity with an LD50 value of 1.02 µg/mL, followed by spinetoram (1.10 µg/mL), chlorantraniliprole (2.74 µg/mL), imidacloprid (3.09 µg/mL), flonicamid (3.94 µg/mL), and fipronil (6.00 µg/mL).…”

Biodiversity and Challenges of Honey Bee Population in Pakistan

Honey bees are important pollinators that support food security and nature’s biodiversity. They are also a source of various honey bee-derived products (api-products) used in the food, pharmaceutical, and cosmetic industries. However, various biological, chemical and physical factors threaten the population and biodiversity of feral and managed honey bees. These challenges have not been elaborated upon in the Pakistani context; therefore, this review aims to identify and describe the menaces to feral and domesticated populations of honey bees in Pakistan. Four honey bee species are reported in the country, with the Western honey bee (Apis mellifera) currently being the main domesticated species. Climate change and urbanization are altering the habitats of honey bees. Additionally, agrochemicals are extensively used to manage emerging pests, exacerbating environmental pollution. The air quality in the majority of urban areas is toxic for honey bees. Although remote forest areas can provide habitat and food for these insects, low forest cover and non-sustainable silviculture are still significant hurdles. Microplastics and antimicrobials are impacting the fitness of honey bees and also appear in their products, making it a One-Health issue. Electromagnetic signals also influence honey bee health and behavior. Overall, all these factors influence honey bee health and colony fitness, ultimately causing population declines in both managed and wild honey bees. The purpose of this information is to assist decision-makers, researchers, beekeepers and educators in comprehending the obstacles faced by the honey bee population within the context of Pakistan.

“…To evaluate the toxicity of AAEO against Apis mellifera, no-choice feeding bioassays were used [30] under laboratory conditions in a plastic container (0.5 L) by following the procedure described previously [31]. Briefly, the following concentrations of AAEO (24,36,48,60, and 72 mg/mL) were prepared in a 50% sugar solution.…”

Interest in developing novel crop protectants has increased in the recent decade due to the harmful effects of synthetic pesticides on humans and the environment. Diaphorina citri threatens the citrus industry worldwide and is the primary vector of phloem-limited bacterium (HLB). However, there is no available cure for HLB. Diaphorina citri management mainly depends on the use of synthetic insecticides, but their massive application leads to resistance in pest populations. Therefore, alternative pest management strategies are needed. Our results indicated that fewer D. citri adults settled on plants treated with AAEO than on control 48 h after release. The psyllids fed on citrus leaves treated with AAEO significantly reduced the honeydew production compared to the control. The AAEO showed potent ovicidal activity against the D. citri eggs with LC50 5.88 mg/mL. Furthermore, we also explored the fitness of D. citri on AAEO-treated and untreated Citrus sinensis by using two-sex life table tools. Our results revealed that the intrinsic rate of increase (r) was higher on untreated seedlings (0.10 d−1) than those treated with an LC20 concentration of AAEO (0.07 d−1). Similarly, the net reproductive rate (R0) was higher for untreated seedlings (14.21 offspring) than those treated (6.405 offspring). Furthermore, the AAEO were safer against Aphis mellifera, with LC50 35.05 mg/mL, which is relatively higher than the LC50 24.40 mg/mL values against D. citri. The results indicate that AAEO exhibits toxic and behavioral effects on D. citri, which can be a potential candidate for managing this pest.
