“…4). Similarly, Bruce et al (2021) also reported that the parasitoid directly alighted on mid-dorsal region of larvae, swiftly introducing an egg and quickly withdrawing the ovipositor. The time taken for drilling and oviposition was around one minute in both the species.…”

Host selection sequence of two parasitoids of under the genus Xanthopimpla Saussure viz., Xanthopimpla flavolineata (Xf) Cameron [Xf] and X. stemmator (Thunberg) (Xs) and suitability of various pupal stages of Sesamia inferens as a factitious host for rearing was investigated. There was no significant difference in egg laying between the single and repeated attempts by both Xf and Xs. The probing time of Xf and Xs in the rice stem with concealed host (2.26± 0.10 and 1.60± 0.13 min) and a hollow stem without a host was found to be 1.19± 0.14 and 0.59± 0.15 min, respectively. However, Xs did not parasitize the naked pupa. The number of ovipositor insertions was 1.50± 0.17 in concealed pupae and 0.92± 0.15 in hollow stem without host. Among the stages of S. inferens pupae tested for acceptance by Xf and Xs, the prepupa was preferred the most followed by one- and two-day-old pupa, while five- and six-day-old pupae were not preferred.

“…betina yang akan melakukan seleksi berdasarkan volume telur inang dan nutrisinya di mana semakin besar volume telur maka menjadi indikator tingginya kandungan nutrisi. Menurut Bruce et al (2021), Trichogramma betina akan melakukan seleksi terhadap calon telur inang dengan mendeteksi bahan kimia yang menjadi penanda apakah telur tersebut telah diparasitasi oleh parasitoid lain dengan menggunakan antenna yang mengandung banyak reseptor dan ovipositor yang memiliki struktur sensorik untuk menilai kualitas inang secara umum.…”

Trichogramma sp. merupakan salah satu jenis parasitoid telur yang mulai banyak dikembangkan sebagai agens pengendalian hayati yang dapat membantu mengatasi masalah hama pada pertanian. Perbanyakan dilakukan secara massal di laboratorium menggunakan telur pengganti yang mudah dikembangbiakkan seperti C. cephalonica yang merupakan salah satu hama gudang terpenting dalam penyimpanan beras dan tepung. Penelitian ini bertujuan untuk memanfaatkan limbah pertanian sebagai media pakan C. cephalonica sehingga dapat diketahui pengaruhnya terhadap pembentukan jumlah dan volume telur yang dihasilkan. Penelitian ini juga menguji lebih lanjut pengaruh media pakan terhadap telur yang dihasilkan terhadap tingkat parasitasi yang dilakukan oleh Trichogramma sp. Penelitian ini menggunakan dua rancangan percobaan yaitu untuk mengetahui pengaruh media pakan terhadap jumlah telur dan volume telur C. cephalonica dengan Rancangan Acak Lengkap dengan 5 perlakuan dan diulang sebanyak 4 kali. Sedangkan untuk pengaruh terhadap tingkat parasitasi Trichogramma sp. menggunakan rancangan acak lengkap dua faktorial 5x3 dan diulang sebanyak 3 kali. Faktor pertama adalah media pakan pada perbanyakan C. cephalonica. Faktor kedua adalah luas pias trichogramma. Hasil penelitian menunjukkan bahwa perlakuan kombinasi media pakan C. cephalonica lebih baik dibandingkan dengan perlakuan tunggal menir yang telah diuji. Perlakuan kombinasi terbaik adalah perlakuan media menir +dedak jagung kasar yang menghasilkan telur terbanyak dan volume telur terbesar. Parasitasi Trichogramma sp. dipengaruhi oleh volume telur, semakin besar volume telur maka semakin efisien tingkat parasitasinya.

“…As a group of generalist egg parasitoids, Trichogramma spp. exhibit the ability to suppress population density of lepidopteran maize pests including, S. frugiperda, Sesamia spp., O. nubilalis, C. partellus, as well as an extended list of lepidopteran pests infesting other crops (Bruce et al, 2021;Jin et al, 2021;Tonğa & Bayram, 2021;Wang & Ferro, 1998). Recent survey programs revealed the presence and natural parasitism capacity of the egg parasitoids of lepidopteran stemborers in the Mediterranean (labels suffixed with M) and Southeastern (labels suffixed with S) regions of Türkiye (Tonğa, 2021;Tonğa & Bayram, 2021).…”

A previous comprehensive survey in the Mediterranean and Southeastern regions of Türkiye investigating the natural egg parasitism of lepidopteran maize pests, Sesamia spp, (Lepidoptera: Noctuidae) Ostrinia nubilalis Hbn. and Chilo partellus (Swinhoe; Lepidoptera: Crambidae) by Trichogramma evanescens Westwood (Hymenoptera: Trichogrammatidae) yielded successful establishment of laboratory cultures of six strains molecularly clustering into two main groups. In this study, the functional response and adult longevity of the strains reared and tested on a factitious host, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) were investigated to provide insights into their potential as candidate biocontrol agents under constant laboratory conditions. The functional response modelling process consisted of two main sequential steps: model selection using polynomial logistic regression and parameter estimation using an iterative maximum likelihood estimation method. The functional response of two strains showed negative linear parameters (type II): HAP068M and HAP268S. Although their attack rate did not differ, the handling time of HAP268S was longer than that of HAP068M. In contrast, four strains had positive linear and negative quadratic parameters (type III) in their functional response: HAP044S, HAP070S, HAP210S, and HAP258M. The strains exhibiting type III functional response did not differ in their handling time, while HAP044S had a higher attack coefficient than HAP070S, HAP210S, and HAP258M. The longevity of both female and male adults significantly differed between strains. More importantly, the females belonging to strains exhibiting type II functional response presented a shorter longevity, compared to those with type III functional response. Males also showed a similar trend in their longevity. This paper discusses the differences in functional response types and estimated parameters of the strains in relation to their relevance for biological control programs and reveals a link between their functional response and longevity as potential reciprocal predictors.
