Sustainable management approach for sucking pests control in betel leaf of Bangladesh

Abstract

Background: Betel leaf is the oldest and now highly paid farmer's crop, but the most vulnerable to insect pests, leading to massive yield drops in Bangladesh. For this reason, the experiment was carried out at the Spices Research Centre, Bangladesh, during the period of January 2018 to December 2018 and to assess the effectiveness of the different bio-rational approach against the betel leaf sucking pests. In this study, BARI Paan-3 was used as a test crop. Studies were important that sucking insect pests to include red mite population (black fly, white fly, red mite and mealy bug) has been found actively around the year in Bangladesh. Results: Studies have shown that sucking insect population (black fly, white fly, red mite and mealy bug) has been found actively year round, whereas the maximum (22.7, 17.2, 16.1, and 14 adult/vine) and minimum (3.2, 2.8, 2.6, and 1.5 adult/vine) were recorded during the month of October and January, respectively. The results explored that the significant variations and the R 2 value suggested that biotic factor contributes 57.9, 50.9, 51.3, and 53.7% variations in black fly, white fly, red spider mite, and mealy bug population. Among approaches, the highest mortality rate (80.56, 84.73, 82.44, and 90.96%) of black fly, white fly, red mite, and mealy bug over untreated control with maximum vine yield (18.61 t/ha) is recorded from sanitation + three alternate spraying of fizimite and antario. Conclusions: It had concluded that sanitation of betel leaf garden along with three alternate spraying of fizimite (sodium lauryl ether) at 1 ml/l and antario WP (Bt + abamectin 0.1%) at 0.5 g/l recommended for an effective management of the betel vine sucking pest complex.

Surveillance and Biorational Management of Rugose Spiraling Whitefly, Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) Infesting Coconut to Reduce the Invasion Threat in Bangladesh

“…D-Limonene, known for its strong aroma, is an active ingredient in several pesticide products that can repel RSW. Our ndings align with previous reports indicating that certain bio-pesticides like Fizimite® 10% (Sodium lauryl ether sulfate), Bio clean® 5% SL, Antario® 0.1% (Bacillus thuringiensis), Success® 2.5% SC (Spinosad), and others effectively combat sucking pests in different crops(Hossain et al, 2020;Rashid et al, 2022;Rahman et al, 2023). The incorporation of bio-pesticides signi cantly enhanced pest management programs and proved compatible with various biorational control methods.…”

“…Hossain et al, 2020;Rahman et al, 2023). Additionally, a multiple stepwise linear regression procedure was used to estimate the impact of bi-weekly mean values of meteorological factors (temperature, humidity & rainfall) on the number of ies per lea et in different bi-weeks and the form of this linear regression model is:…”

Integrated management of thrips-mite and borer complex attacking chilli

“…Up to date, a small number of reports have been available on biorational based management of chilli Thrips. Hossain et al [10] have reported that alternate application of Antario and Fizimite were found effective against betel leaf sucking insect pest. Celiz et al [11] have stated that Thrips were successfully controlled by bio-pesticide called Matrine.…”

“…Our results showed that the lowest mite population was recorded from the treatment spraying of Kmite, Soil recharge, HNPV and SNPV along with pheromone mass trapping which was statistically similar with the spraying of Fizimite and Biotrin along with the blue sticky trap and pheromone mass trapping (Table 2). Biopesticide such as Fizimite was found effective for managing sucking pest like red mite [10] . After fruit setting, borer insect pests such as Helicoverpa armigera and Spodoptera litura infest chilli fruits.…”

“…IPM technologies included bio-pesticides and other mechanical approaches can be the alternative of chemical pesticides for controlling insect pests. Bio-pesticides such as sodium lauryl ether sulphate and Bt + Abamectin suggested for a sustainable management option for controlling sucking insect pests of the betel vine [10] . However, bio-pesticides Matrine can effectively control Thrips and different Lepidopteran borer insect pests [11,13] .…”
