“…Sabhat et al (2011) evaluated that the larval growth rate, weight and survival rate were greatly affected by ecological factors, quality of leaf and rate of food consumption. However, Zulfiqar et al (2022) recorded better growth in the Bulgarian race as compared to Chinese and Korean races reared in the local climatic conditions of Gujrat Pakistan. They performed their study in the spring season on newly sprouting mulberry leaves whereas our study was conducted in the autumn season on comparatively matured and less succulent leaves.…”

“…According, to our results Chinese race has the potential to perform well when fed with the local mulberry variety (M. alba) in local climatic conditions of Lahore and shows better performance almost in all biological and economic parameters as compared to the other two races. On the other hand, Zulfiqar et al (2022) reported that in the spring season bivoltine Bulgarian race showed better results as compared to Chinese and Korean races for biological and commercial parameters when fed with local mulberry leaves in local climatic conditions of Gujrat Pakistan, while they did not mention the type of local mulberry.…”

“…In our study, among three silkworm races Chinese silkworm race (Haukaned 2 strain) showed better hatchability at high temperatures than the Bulgarian race (KK × Hesa 1 × Vesletz 2 × Gergana 2). Zulfiqar et al (2022) observed that the Bulgarian race showed better tolerance against high temperatures than the Chinese and Korean silkworm races respectively. While they did not mention the silkworm strain they used in experiments.…”

| Sericulture is a labor intensive cottage industry that has great potential for poverty alleviation. In Pakistan, the farming community so far has not identified the specific race suitable for the specific climatic zones of Pakistan in terms of yield, performance and adaptability. The current study was conducted to find out the optimum hatching and rearing conditions of three silkworm races (Chinese, Bulgarian and Pakistani) and to compare their biological and economic traits at optimum conditions. The silkworm eggs were hatched at a range of temperatures (21-30°C) and humidity levels of 75-80-% and 80-85% respectively. The silkworms hatched at optimal conditions were provided variable meals and the leaves consumption rate was calculated. In a separate experiment, the 5 th instar silkworm larvae were assessed for biological and economic traits. The results of this study exhibited that Chinese silkworm eggs showed better hatchability at high temperatures. The larvae of the Chinese race also showed an increased leaf consumption rate with an increase in the number of meals (6) per day. Moreover, a significant increase in biological traits including average larval weight (0.979±0.038) and ratio silk gland to body weight (27.386 % ±0.843) was also observed in this group as compared to other groups. The economic traits including cocoon length and width as well as fibroin content of larvae of the Chinese race were significantly higher as compared to Pakistani and Bulgarian races. It is concluded that the Chinese silkworm showed better adaptation and produced a high yield in the local climatic conditions of Pakistan.Novelty Statement | Sericulture is a declining cottage industry. One of the major limitation faced by the farmers is the availability of most appropriate silk seed that suits the local environmental conditions. This research study suggests that the silkworms of Chinese race are better adapted and produce more yield in local climatic conditions of Punjab, Pakistan.

“…The silkworm ( B. mori ) eggs of Bulgaria Race (Hybrid) were obtained from the Sericulture Wing; Forestry, Wildlife and Fisheries Department, Lahore. Silkworm eggs were incubated under standard light (12 h light: 12 h dark), optimum temperature (25–28 °C) and humidity (70–75 %) for 8 days in the Research Laboratory of Sericulture Wing; Forestry, Wildlife and Fisheries Department, Lahore (31° 36′ 28″ N, 74° 18′ 11″ E) [ [ [28] , [29] , [30] , [31] , [32] ]].

“…For the Cocoon weight, ten cocoons were picked randomly from pupated cocoons as described by Zulfiqar et al (2022) [28] , in each of the three replications and each cocoon was weighed in grams using high precision weighing balance described above. The weighed cocoons were then cut longitudinally on the side so that the pupa could be removed and weighed, with a lot of care not to harm the pupa.…”

The domesticated silkworm Bombyx mori and Eri worm (Samia cynthia ricini) are bivoltine and multivoltine, feeding exclusively on mulberry and castor leaves, respectively. The domestication of silkworms has made them highly sensitive to fluctuations in temperature and relative humidity. The research determined the performance of silkworm reared inside pre-constructed structures with equal dimensions (4 m x 4 m x 3 m height), with iron roof; timber walled (L1) and mud walled (L2). Greenhouses with four flaps open (L3), three sides open (L4), two sides open (L5), one side open (L6) and completely enclosed (L7), and concrete walled (L0) were used. The survival percentage, larval duration and cocoon quality and quantity were tested and compared. The temperature and relative humidity were recorded. The mean temperature of structures during rearing ranged between 22.73 °C±1.86 (L0) and 31.63 °C±0.81 (L7) during the wet season with a similar trend in the dry season, the mean relative humidity of 33.26%±7.29 (L1) and 43.18%±9.53 (L0) during the wet season and 33.11%±7.27 (L1) and 42.16%±7.38 (L7). Larval duration was longest in L2 for both B. mori and Eri during the wet season. Larval survival was highest in L2 (76.73±4.20%) and L0 (78.70%) during the wet and dry season respectively. A similar trend obtained in L2 (77.00%) and L0 (80.10%) for Eri in wet and dry season respectively. The cocoon weight was highest in structure L2 (0.86±0.03) during the dry season, L5 (2.78±4.30) during the wet season. Eri cocoon weight was highest in L0 (2.35±0.49) during the wet season and highest in L3 (2.44±0.34) in the dry season. The longest significantly different Filament length for B. mori was in L2 (1377.80±150.17 m). During the dry season L3 (1382.80±117.23m) was the longest. For the Eri the longest filament length was from L2 (437.6±32.26). The seasons did not influence average survival, filament length and weights from the tested structures.
