“…A reduction of female life span in multiple mating is due to the cost of mating itself, such as physical damage by repeated copulation and aging, and the cost of an increased egg production (Chapman et al 1998;Arnqvist and Nilsson 2000;Yanagi and Miyatake 2003;Campbell 2005). The number of matings is usually, but not always, correlated with egg production in many insect and mite (Kawagoe et al 2001;Orsetti and Rutowski 2003;Campbell 2005;Pappas et al 2007). …”

Females of some insects and mites that mate repeatedly (multiple-mated females) or that have limited food supply have a shortened life span, compared to females that are allowed to mate only once (single-mated females) or that have ample food. The present study focused on the relationship between mating frequency and various reproduction-related parameters in a commercial strain (Spical) of the phytoseiid mite Neoseiulus californicus (McGregor) (Acari: Phytoseiidae). The impetus for this study came from the previous finding that single-mated females displayed an extremely long postoviposition period (ca. 60 days), accounting for more than 75% of the total adult longevity. In the present study it was found that the postoviposition period in the multiple-mated females was shorter than in the single-mated females and that longevity was gradually shortened with increasing mating frequency. Total egg production in females that mated twice or more was higher than in single-mated females, but egg production did not increase further with more than two matings. Single- and multiple-mated females ceased oviposition on the 24th and 34th day of adult life, respectively; multiple-mated females produced only male progeny on and after the 30th day. The postoviposition period of multiple-mated females was 40% shorter than that of single-mated females. Yet, the postoviposition period of the multiple-mated females is still more than 30 days, suggesting that other factors besides mating frequency have an influence on the prolonged postoviposition period. The reproductive ability of the Spical strain females gradually decreased with increasing virgin period (i.e. with increasing age), but they did not lose their reproductive potential--not even when mating was delayed for more than 2 months (i.e. females remained virgin for 70 days).

“…In this treatment the survival of females that had access to males was significantly lower than those without males (Figure 4.2). This has been previously reported in Sitophilus oryzae where continuous exposure of female S. oryzae to one or more males decreased the survival rate significantly as opposed to females that had no access to males (Campbell, 2005). Presumably these females were, somehow, stimulated to deposit all their potential eggs and died soon after.…”

“…This indicates that females mate readily irrespective of their age and that they might be stimulated to lay all their eggs before death. The phenomenon of reduced survival after exposure to one or more males has been observed in Sitophilus oryzae (Campbell, 2005).…”

Characterisation of variables associated with the flight behaviour of the rust-red flour beetle (Tribolium castaneum)

Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) causes significant losses to stored grain products. This problem is aggravated by the development and spread of resistance to various grain protectants, especially the fumigant phosphine. Studying the dispersal behaviour of T. castaneum will help in understanding the spread of resistance. Active dispersal in T. castaneum occurs by both walking and flight. Flight enables dispersal across a wider geographical area and increases the probability of spreading resistance genes geographically. Dispersal of pests also has implications for understanding the ecology of resident populations and thus also for improving food security effectively. Therefore, a good understanding of T. castaneum dispersal by flight is critical to managing this pest and its resistance to phosphine.The research reported here was designed to study factors that influence the flight of these long-lived beetles. Various techniques were employed, in both the laboratory and field, to investigate a broad range of factors that may influence T. castaneum flight behaviour. I also explored the use of nanoparticles as novel external markers for small insects, with an emphasis on their use in markrecapture studies of T. castaneum. The ability to gauge the dispersal distance of these insects accurately would aid considerably in understanding the spatiotemporal dynamics (and gene flow) of this species across landscapes.Chapter 2 investigated the flight propensity of T. castaneum at two different ages at the same time (old (~12 weeks) and young (~2 weeks post-emergence)). First generation laboratory cultures of field-collected beetles were used to avoid the known effects of protracted laboratory culturing.Flying beetles were captured individually using a customized trap, and their age, sex, weight, size, fat content, fecundity, polyandry and lipofuscin intensity (as an estimate of age) were determined.Beetles were also collected from the culture medium and considered to be resident (non-flyers). The assays indicated that flight propensity declined significantly with age as more young beetles took to flight than old ones. Flight was not affected by sex, body size or weight but lipofuscin intensity of old beetles was similar to young beetles in culture, so it is not an indicator of age. Since, its levels were only significantly higher in young flying females than young resident females it may be related to the individual's metabolic status. Fecundity assessments indicate that the total fecundity was not related to age or flight as no significant differences were found between resident and flying beetles across and between all age groups.Microsatellite markers were used to assess parentage of offspring. They confirmed that females of iv this species are polyandrous in the field (as expected from their polyandry in laboratory cultures).The number of males inseminating females in the field ranged from one to four, and this held too for first generation laboratory cultures (which is reported in Chapter 3 ...

“…Progeny size, however, was reduced. Campbell (2005) also found that exposure of one female to five males significantly decreased the number and size of progeny produced. Cay et al (2009) reported that females of Callosobruchus maculatus (F.) (Coleóptera; Bruchidae) kept continuously with males have reduced lifetime egg production compared with females mated once and then isolated from males.…”

“…An additional cause may be the effect of multiple matings of males with females. Research by Campbell (2005) on the rice weevil, Siiophilus oryzae L. (Coleóptera: Curculionidae), found that continuous exposure to one male increased tbe lifetime fecundity of females by increasing the period of time that eggs were produced, compared with mating with one male for a specific mating interval. Progeny size, however, was reduced.…”

Eucryptorrhynchus hrandti (Harold) (Coleóptera; Curculionidae) was identified in China and studied in quarantine in tbe United States as a potential biological control agent for the invasive weed, tree of heaven, Ailanthus altissima (Mill.) Swingle (Sapindales: Simaroubaceae). Studies on its general biology and development, and the most efficacious rearing method were conducted. E. brandti is univoltine. The metathoracic sternite and first abdominal segment are convex in females and concave or flat in males. Females are larger than males. Female and male sagittal measurements averaged 11.50 ± 0.14 (± SEM) and 10.35 ± 0.09 mm, respectively. Transversal measurements averaged 4.22 ± 0.06 and 3.73 ± 0.05 mm for females and males, respectively. Mean weight of females and males were 0.10 ± 0.003 and 0.07 ± 0.002 g, respectively. Females lived longer than males, averaging 66.3 ± 6.8 d and 46.5 ± 7.3 d, respectively. The egg stage averaged 5.0 ± 0.9 d, and the larval stage had six stadia and developed in 110 ± 15.0 d; the pupal stage was 16 ± 7.0 d at 25°C. A method for rearing E. brandti on cut A. altissima billets under quarantine conditions was developed. The most efficient egg-to-adult rearing method involved caging 12 males and 12 females or 24 males and 24 females for 7 d on 23-92-cm-long biUets. Duration up to 3 wk after cutting did not affect adult emergence. This information will facilitate laboratory rearing and conducting host specificity tests to determine agent impact on nontarget species.
