ABSTRACTThe pre-oviposition period is critical in the development of reproductive organs in ladybirds, but there is little information about the main causes of this period. The pre-oviposition period in the ladybird Cryptolaemus montrouzieri was influenced by prey consumption, suggesting that there is a nutritional aspect from food intake that must affect ovary maturation after adult emergence. We also investigated whether feeding on non-prey food affects the maturation of ovaries. We have found that newly emerged females of C. montrouzieri have no developed ovary, and when feeding on adults of the mealybug Planococcus citri and in the absence of males, 5 days are required for full ovary development and egg maturation. Females feeding only on honey did not develop ovarioles even in 7 days. The ovarioles developed in each female on each side of the ovary is around 10 on a daily basis, with no significant difference between the left and the right side each day. On the fifth day, a great number of mature eggs were found, remaining constant on the following sixth day. Our results suggest that food quality, rather than just feeding, is a fundamental step to start the physiological chain that is responsible for the ovary development.KEYWORDS: Ladybugovariesdevelopmentovipositionallocation AcknowledgmentsWe thank Melyssa Gabriely Silva, Jorge de Oliveira Gomes Júnior and Helloyza Morais Rodrigues da Silva for their assistance in the complementary experiment and further data collection.Disclosure statementNo potential conflict of interest was reported by the authors.
摘要产卵前期是瓢虫生殖器官发育的关键时期，但关于产卵前期的主要原因却知之甚少。蒙氏隐瓢虫的产卵前期受猎物摄取量的影响，这表明食物摄取量在营养方面影响了成虫羽化后卵巢的成熟。我们还研究了进食非猎物食物是否会影响卵巢的成熟。我们发现新出的montrouzieri雌虫没有成熟的卵巢，在没有雄虫的情况下，以柑橘扁球菌成虫为食，卵巢完全发育和卵子成熟需要5天。仅以蜂蜜为食的雌性在7天内没有卵巢发育。每只雌性卵巢两侧每天发育的卵巢在10个左右，左右两侧每天无明显差异。在第五天，发现了大量成熟的卵，并在接下来的第六天保持不变。我们的研究结果表明，食物质量，而不仅仅是喂养，是启动负责卵巢发育的生理链条的一个基本步骤。我们感谢Melyssa Gabriely Silva、Jorge de Oliveira Gomes Júnior和Helloyza Morais Rodrigues da Silva在补充实验和进一步数据收集方面的帮助。披露声明作者未报告潜在的利益冲突。

ABSTRACTA population of the porcelain crab Pachycheles laevidactylus was evaluated based on sex ratio, sexual dimorphism, reproductive intensity, relative growth and sexual maturity. The porcelain crabs were identified, sexed and measured as follows: carapace (CL, length; CW, width), chelar propodus (PL, length; PH, height) and abdomen (AL, length; AW2 and AW5, the width of the 2nd and 5th abdominal somite, respectively). For the 1,109 specimens analyzed, the sex ratio was 1:1, but contrasted in some seasons. Females were significantly larger than males, and ovigerous females were recorded in all seasons, with greater intensity in autumn and winter. In males, the biometric ratios of the major chelar propodus (PHxCL and PLxCL) showed positive allometry regarding body size, with a reduction in the allometry rate after puberty. The same occurred with females for the biometric ratios of the abdomen (AW2xCL and AW5xCL). Males attain morphological sexual maturity at 3.48 mm CL, earlier than females, which occurred at 5.00 mm CL. In this study, P. laevidactylus matured with a larger size than reported for others analyzed in the temperate zone. It is the first study addressing aspects of the population biology of P. laevidactylus in a region with a subtropical climate.KEYWORDS: Allometrygrowthmorphologyreproductionsexual maturity Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingWe want to thank the National Council for Scientific and Technological Development - CNPq (Research Fellowship Grant to MAAP: # 305957/2019-8) and the São Paulo Research Foundation - FAPESP for the financial support provided to MAAP (# 1998/6055-0, # 2022/05614-2, # 2009/14725-1 and # 2014/50438-5) and the Master Fellowship Grant MCAJ (# 2019/16581-9).

ABSTRACT The leech Whitmania pigra is well known in traditional Chinese medicine for promoting human blood circulation and alleviating blood stasis. To evaluate its suitability as bait for this neonate leech, we investigate the reproductive efficiency of the snail Radix plicatula under laboratory conditions. Furthermore, the effects of the size of R. plicatula on the growth of newborn W. pigra were evaluated. Wild snails laid eggs in mid-March with body weight >0.223 g and peaked at the beginning of April to early May. The accumulated number of eggs was 1489.70 ± 895.98 and 2145.67 ± 694.47 separately for individual and paired snails (P = 0.083). The time elapsed up to the hatching of the first egg in the four collected egg masses ranged from 12 to 18 days, and the hatching percentage ranged from 97-% to 100-% . The predation rate of the newborn W. pigra was significantly higher when feeding on small snails than on medium and large snails (P < 0.01). Furthermore, increased snail size resulted in decreased leech growth and survival rates. The investigations demonstrated that the snail R. plicatula could serve as a suitable living bait in the rearing of W. pigra to help alleviate the scarcity of leech on the market.

ABSTRACT We investigated the relative growth and sexual maturity (gonadal and morphometric) of Libinia spinosa. Crabs were sampled at Ubatuba from January to December 2000, using trawls. Based on allometric growth, males were grouped into juveniles (MJ), adolescents (MAd) and adults (MA) based on the relationship CPL (major cheliped propod length) vs. CW (cephalothorax width), all with positive allometric growth. For females, the relationship AW (abdomen width) vs. CW allowed segregating juveniles (FJ) from adults (FA), with positive allometric growth for FJ but isometric growth for FA. The morphometric maturity evidenced for MAd varied from 33.7 mm to 34.5 mm and for MA and FA. The size at which 50% of individuals reach the morphometric sexual maturity was L50 = 50.1 mm for males and L50 = 37.3 mm for females. Gonad maturity was L50 = 33.7 mm for males and L50 = 36.9 mm for females. Through relative growth analyses, we identified an adolescent male group (prepuberal phase). These individuals presented mature gonads, enabling them to copulate with females. These adolescent males may reproduce while avoiding competition with adult males, as it happens in other species of Majoidea that present more than two morphotypes in the population.

ABSTRACT The main Spondylus limbatus population parameters were estimated based on the analysis of individual growth and reproductive aspects of specimens collected monthly (n = 30) from January to December 2009 in the fishing area of Agua Verde, Gulf of California. The size structure determined from shell measurements was 82–167 mm and the direct reading of shell sections indicated ages of 1–14 years. The data were adjusted to the von Bertalanffy, Gompertz, logistic, Richards and Schnute (Type 1) growth models. The von Bertalanffy model provided the best fit to describe individual growth in this species (SH∞ = 142.7 mm, k = 0.47, t0 = −0.20 years). The spawning season was determined through gonadal histology, and the size and age at sexual maturity through a logistic model. Reproductive activity occurred from March to September, with spawning peaks in July and August. The size and age at sexual maturity were 10.8 mm and 2.7 years, respectively. This information provides the necessary knowledge to implement management measures in the area. We recommend independent studies to establish management measures for each fishing area.
