Chemical insecticides are intensively used in agriculture which cause negative effects on environmental sustainability by increasing pest tolerance and continuous action on local fauna. In contrast to chemical insecticides, biological insecticides target specific pests, minimizing their impact on the surrounding environment. However, most of the natural insecticides available in the market are expensive for farmers in the Central Asian region. This study is the first evidence of the effectiveness of local entomopathogenic nematodes (EPN) from the arid zone of northern Kazakhstan that can be used as an alternative to export EPN products. The laboratory experiment is conducted with two local and two commercial Steinernema feltiae and Steinernema carpocapsae , which are applied to larvae of Tenebrionidae . The experiment design is randomized with four doses of EPN (100, 200, 300, and 400 IJ/cm 2 ) and a control (without EPN). According to the experiment results, one out of two local EPNs (AF29 at dose 100 IJ/cm 2 ) caused a high mortality rate (67%) among larvae. This finding confirms that local EPNs can compete with commercial EPNs and potentially be used as insecticidal agents.

The melon fly, Bactrocera cucurbitae is serious pest attacks fruits and vegetables. The manipulation of male mating behavior that displays acoustic signals is one of the steps in the behavior-based control strategy of B. cucurbitae . The first study period determines the courtship song characteristics, frequency, and occurrence time. The recording was carried out when B. cucurbitae was mated using recording devices at 04.00 –0 7.00 pm. The results show three sounds produced before copulation, namely, calling, courtship, and stimulating, with frequencies 274.30 ± 3.29 Hz, 284.65 ± 2.00 Hz, and 304.36 ± 1.82 Hz. B. cucurbitae courtship song began at 04.00 –0 6.26 pm. The second study was performed to determine the effect of experimental acoustic playback stimulus on the selection of mating pairs by females. The acoustic playback stimulus is made synthetically by playback of two channels, namely, calling and courtship sounds, with frequencies of 274 and 284 Hz at a sound pressure level (SPL) of 85 dB. The experimental results of acoustic playback stimulus show that the sexual behavior of female B. cucurbitae was disrupted and marked by the decreased number of copulations during SPL is high, resulting in the overlapping calling and courtship sounds frequencies that impair signal detection .
