“…Similar patterns of vertical oviposition preference (e.g. Smith 1988; Grieshop et al 2014) or preferences between upper/lower parts of leaves (Gardner & Hoffmann 2020) are often observed in Trichogramma, but, again, the actual contributions of photo-or geo-orientation are usually left hypothetical. Explicit studies of these traits remain extremely scarce.…”

“…per hectare could reduce the population of sugarcane shoot borer while 250,000 eggs are required per hectare to control sugarcane stem borer (Cascone et al, 2014). In some countries, such as China, the Philippines, India, and Taiwan, T. chilonis is used as a biological control agent in sugarcane plantations (Grieshop et al, 2014). In Indonesia, T. chilonis was first developed to address the problem of stem borer in several sugar cane plantations in Java which was later introduced to Lampung after similar problems arose.…”

This community services activity was conducted together with a partner that is Benong II Farmers Group, in the Kalibuaya Village, Telaga Sari, Karawang. The problem that faced by partners is a lack of understanding of plant pest organisms (OPT), especially plant pests and diseases, as well as a lack of knowledge about the natural enemies. Knowledge and skills of the Benong II Farmers Group in the Kalibuaya Village, Telaga Sari, Karawang regarding the management and control of rice stem borer that environmentally friendly, especially biological control using parasitoid Trichogramma sp. needs to be improved. The evaluation results show that counselling and training on the breeding of natural enemies Trichogramma sp. resulting in the development and progress of the behavior, attitudes, and skills of farmers. There are four main results of the research. The results are (1) farmer more understand of the use of biological agents for IPM-based rice pest and disease control; (2) want to implement the control of rice stem borer Scirpophaga sp. by using Trichogramma sp.; (3) more skilled in monitoring the presence or absence of pests in rice plantations in the field; and (4) more active in finding out to community service teams, farmer group leaders, and POPT / field extension officers about how to mass culture theTrichogramma sp. and it's release techniques in the field.

“…The first was conducted at a smaller scale and examined the impact of microhabitat complexity on single females (Grieshop et al 2008), while the second was conducted at a much larger scale and examined the foraging efficacy of mass-released parasitoids on retail shelving units (Grieshop et al 2007). The failure of T. deion to outperform the other two species in this experiment may be due to either: 1) the difference in spatial scale among the present and previously published experiments, or 2) the homogeneous nature of the arenas used in this trial.…”

“…Because the presence of a single P. interpunctella larva, pupa, or adult can result in the total economic loss of the product (Subramanyam et al 2001), location of individual host eggs is of critical importance for Trichogramma used in retail stores or warehouses. Other studies comparing the three species' performance at either a finer spatial scale in response to microhabitat complexity or at a broader spatial scale examining the ability of mass-released Trichogramma to locate eggs on shelving units found that T. deion parasitized/killed significantly more P. interpunctella eggs than the other two species (Grieshop et al 2007, Grieshop et al 2008). …”

Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley — as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to forage in Plexiglas arenas with four different spatial arrangements of host eggs, nine single-egg patches), nine four-egg patches, 36 single-egg patches, and 36 four-egg patches. No significant differences were found among species in the number of patches parasitized. As expected, all three species parasitized the most eggs in the 36 four-egg patch treatment and the least in the nine single-egg patch treatment. T. deion parasitized significantly more eggs than T. pretiosum on the nine four-egg patches. T. ostriniae parasitized significantly more patches when intrapatch density was greater, regardless of interpatch density. In contrast, T. deion only parasitized more patches at the greater intrapatch density when the interpatch density was low. Patch density had no effect on T. pretiosum. The spatial pattern of parasitism was more aggregated for T. deion and T. ostriniae in the 36 four-egg patches treatment compared to the 36 single-egg patches treatment. Therefore, intrapatch density was more important than interpatch density for T. ostriniae, and potentially for T. deion, but not for T. pretiosum. T. deion may be the best candidate for augmentative biological control because it parasitized either slightly or significantly more eggs than the other two species in all four treatments. Furthermore, the pattern of parasitism by T. deion in the 36 four-egg patches treatment was the most aggregated among the three species, suggesting a more thorough searching pattern. In contrast, T. pretiosum had the least aggregated pattern of parasitism and therefore may have used a more random foraging pattern.
