Effects of abamectin and deltamethrin to the foragers honeybee workers of Apis mellifera jemenatica (Hymenoptera: Apidae) under laboratory conditions

Abstract

This study aimed at evaluating the toxicity of some insecticides (abamectin and deltamethrin) on the lethal time (LT) and midgut of foragers honeybee workers of were studied under laboratory conditions. The bees were provided with water, food, natural protein and sugar solution with insecticide (concentration: 2.50 ppm deltamethrin and 0.1 ppm abamectin). The control group was not treated with any kind of insecticides. The mortality was assessed at 1, 2, 4, 6, 12, 24, 48, and 72 hour (h) after insecticides treatment and period to calculate the value of lethal time (LT). But the samples the histology study of midgut collected after 24 h were conducted by Scanning Electron Microscope. The results showed the effects of insecticides on the current results show that abamectin has an adverse effect on honeybees, there is a clear impact on the lethal time (LT) was the abamectin faster in the death of honeybee workers compared to deltamethrin. Where have reached to abamectin (LT = 21.026) h, deltamethrin (LT = 72.011) h. However, abamectin also effects on cytotoxic midgut cells that may cause digestive disorders in the midgut, epithelial tissue is formed during morphological alterations when digestive cells die. The extends into the internal cavity, and at the top, there is epithelial cell striated border that has many holes and curves, abamectin seems to have crushed the layers of muscle. Through the current results can say abamectin most toxicity on honeybees colony health and vitality, especially foragers honeybee workers.

Transfer of plant protection products from raspberry crops of Laszka and Seedling varieties to beehives

“…It most likely acts on GABA receptors by activation and blocking of the postsynaptic potential (Fritz et al 1979 ) and glutamate-gated chloride channels (Clark et al 1995 ). In bees, abamectin also affects cytotoxic midgut cells that may cause digestive disorders in the midgut; epithelial tissue is formed during morphological alterations when digestive cells die and is particularly dangerous for the foraging workers (Aljedani 2017 ). Cypermethrin applied at both plantations (AI of Cyperkill Super 25 EC) belongs to pyrethroids.…”

The Effectiveness of Abamectin Insecticide in Suppressing the Population of Liriomyza spp (Diptera: Agromysidae) on Red Onions

“…Some other research results showed that Abamectin indeed was highly effective in suppressing the population of Liriomyza (Ramesh and Ukey, 2007;Saad et al, 2007). Abamectin insecticide has caused the malfunction of some cells in those insects' digestion, more especially in the midgut (Aljedani, 2017). Abamectin application had decreased Liriomyza larvae significantly lower population of adult Liriomyza, spp.…”

“…Type of insecticides that are commonly used by farmers contained Abamectin and Spinoteram active materials, working in contact, gastric and systemic that can cause cell malfunction in the insects' digestive tract, especially in the midgut (Aljedani, 2017;Srinivasa et al, 2014). Therefore, there is a need for pest management by applying broad-spectrum insecticide applications (Salvo and Valladares, 2007).…”

Pengaruh Frekuensi Dan Aplikasi Insektisida Abamectin Terhadap Kelimpahan Populasi Dan Persentase Serangan Lalat Pengorok Daun Liriomyza SPP (Diptera: Agromysidae)

“…Secara umum jenis insektisida yang banyak diterapkan oleh petani, berbahan aktif Dimohipo, Curacron, Abamectin dan Spinoteram Arfan et al, 2018). Salah satu jenis insektisida dalam mengendalikan hama lalat pengorok daun yaitu Abamectin yang bekerja secara kontak, lambung dan sistemik (Srinivasa et al, 2014) menyebabkan tidak berfungsinya beberapa sel-sel pada bagian pencernaan serangga khususnya pada midgut (Aljedani, 2017 (Herlinda et al, 2005;Shahabuddin, 2012 di pertanaman bawang merah, yaitu ditemukan spesies Liriomyza spp sejak tanaman berumur masih berumur muda 2 MST-4 MST. Kondisi demikian diduga tanaman memiliki kandungan nutrisi yang dibutuhkan oleh imago dan larva (Herlinda et al, 2005) sedangkan pada umur tanaman 5-8 MST diduga terjadi pengerasan pada jaringan tanaman sehingga stilet tidak mampu mendukung dalam melakukan aktivitas makan.…”

“…Kemampuan insektisida abamectin dalam menekan perkembangan larva Liriomyza, spp, hal ini mungkin disebabkan oleh cara kerja dari insektisida abamectin 18 EC bekerja secara kontak, lambung dan sistemik (Srinivasa et al, 2014). Penggunaan insektisida abamectin menyebabkan tidak berfungsinya beberapa sel-sel pada bagian pencernaan serangga khususnya pada midgut (Aljedani, 2017). dan juga bekerja dengan cara menghambat transmisi syaraf (Kola et al, 2015)…”
