Determining the best ratio of females to males of an insect's natural enemy is important for maximising population increase and promoting population establishment of a natural enemy. In this study, copulation behaviour, fecundity, progeny fitness and rate of population increase for the flea beetle, Agasicles hygrophila Selman & Vogt (Coleoptera: Chrysomelidae), were compared at different female percentage treatments (i.e., 80%, 66.7%, 50%, 33.3% and 20% females). The results showed that the… Expand

TLDR
Interaction assays with one of the dominant local parasitoids, Diglyphus isaea (Walker; Hymenoptera: Eulophidae), using Liriomyza huidobrensis (Blanchard; Diptera: Agromyzidae) was assessed through sole, simultaneous and sequential releases. Expand

TLDR
A system-dynamic modelling approach for the biocontrol of the invasive plant species Alternanthera philoxeroides using its natural predator, Agasicles hygrophila, as a biocentrol agent, indicating that the control of this new invasive plant is possible, as long as several releases of the biOControl agent are made over time.

Alligator Weed Alternanthera philoxeroides (Mart.) Griseb.
TLDR
It is essential to integrate physical, chemical and biological means, intensify regional management and adopt time-and site-specific optimal measures for the control of alligator weed. Expand

Performance of Agasicles hygrophila (Coleoptera: Chrysomelidae), a biological control agent of invasive alligator weed, at low non-freezing temperatures
TLDR
The results indicated that A. hygrophila has the capacity to stand relatively low non-freezing temperatures for short durations, which would help it to overwinter and establish natural populations in some areas, especially in areas where protected cultivations are extensive and ambient temperatures are not as low as those in the open field.

Maternal adjustment of the sex ratio in broods of the broad-horned flour beetle, Gnathocerus cornutus.
TLDR
It is reported that females of the broad-horned flour beetle can plastically adjust the sex ratio in their broods in response to environmental quality and how plasticity can resolve a long-standing question about the conditions underlying the evolution of biased sex ratios is discussed. Expand
Sex ratio bias in the dung beetle Onthophagus taurus: adaptive allocation or sex-specific offspring mortality?
TLDR
It is demonstrated that offspring mortality is contingent on the amount of resources provisioned by females and that sons have greater nutritional demands than daughters during development, leading to higher mortality. Expand
The effect of temperature on the development and survival of Agasicles hygrophila Selman & Vogt (Coleoptera: Chrysomelidae), a biological control agent for alligator weed (Alternanthera philoxeroides)
TLDR
Agasicles hygrophila was introduced into New Zealand in 1982 and the number of eggs laid subsequently decreased as the time adults were exposed to chilling was increased, and with increased chilling time. Expand
Inbreeding and selection on sex ratio in the bark beetle Xylosandrus germanus
TLDR
The results confirm that caution is needed when inferring mating systems from sex ratio data, especially when a lack of biological detail means the use of overly simple forms of the model of interest. Expand
Female ambrosia beetles adjust their offspring sex ratio according to outbreeding opportunities for their sons
TLDR
It is demonstrated that males of a haplodiploid ambrosia beetle with LMC disperse to seek additional matings, and brood sex ratios increase with outbreeding opportunities in the field, the first study showing that male dispersal options may influence individual female sex allocation decisions in species with strong LMC.

Influence of temperature on adult longevity, oviposition and fertility of Agasicles hygrophila Selman & Vogt (Coleoptera: Chrysomelidae)
TLDR
Agasicles hygrophila, a leaf feeding Chrysomelid beetle, was introduced into New Zealand in 1982 for the biological control of alligator weed and laboratory studies showed that egg laying rate and viability were optimal at a constant temperature of 25°C. Expand
Massive rearing of the alligator weed flea beetle,Agasicles hygrophila(Coleoptera:Chrysomelidae),in the laboratory
TLDR
It is found that the periods from early 1st instar larva transferring to fresh plants (or leaves) and from fully developed 3rd instar larvae in transition to pupation were both the critical phases for successful high-density rearing. Expand
Intralocus sexual conflict and offspring sex ratio.
TLDR
Broad-horned flour beetles are able to adaptively bias sex ratio and recoup indirect fitness benefits of mate choice through biasing of offspring sex-ratio to reduce the production of the lower-fitness sex, so that for example, broods produced by high-f fitness females should contain fewer sons.

Cytogenetic effect of Alternanthera philoxeroides (alligator weed) on Agasicles hygrophila (Coleoptera: Chrysomelidae) in its native range
TLDR
Investigation of the effect of four A. philoxeroides populations with varying cytogenetical characteristics on plant–insect interaction with A. hygrophila found plant genetic characteristics could constrain insect development and reproduction, providing an alternative explanation for the restricted success of biological control of alligator weed.
