Intraspecific variability in number of larval instars in insects.
The number of larval instars varies widely across insect species. Although instar number is frequently considered to be invariable within species, intraspecific variability in the number of instars is not an exceptional phenomenon. However, the knowledge has remained fragmentary, and there are no recent attempts to synthesize the results of relevant studies. Based on published case studies, we ...
متن کاملSoldier production strategy in lower termites: from young instars or old instars?
We constructed a mathematical model to explain from which instars soldiers should be produced to maximize the growth rate of a termite colony. The model is based on the demography of the lower termite's colony: many of them feed inside the nest. The model predicts the following: (1) When the colony is young (it still has enough food and needs a high ratio of soldiers to workers) it will produce...
متن کاملComparative Morphology of the Early Larval Instars of Aech aegqpti and A. &tiai in Thailand
The chaetotaxy and structures of the head, thorax and abdominal segments VIII and X of the first 3 instars of A&U aegqpti (Linnaeus) and An hUthi Huang, are tabulated and illustrated. Characters are tabulated that will permit identification of the 4 larval stages within each species and differentiate the first 3 larval instars of aegqp;ti and beti& A serial acquisition of certain thoracic setae...
متن کاملMicrobial Gut Diversity of Africanized and European Honey Bee Larval Instars
The first step in understanding gut microbial ecology is determining the presence and potential niche breadth of associated microbes. While the core gut bacteria of adult honey bees is becoming increasingly apparent, there is very little and inconsistent information concerning symbiotic bacterial communities in honey bee larvae. The larval gut is the target of highly pathogenic bacteria and fun...
متن کاملLarval and pupal morphology of three species of the genus Psammoecus Latreille (Coleoptera: Silvanidae: Brontinae) in Japan with reference to the number of larval instars.
The last instar larva and the pupa of Psammoecus scitus Yoshida & Hirowatari, all instar larvae of P. simoni Grouvelle, and the last instar larva of P. hiranoi Yoshida & Hirowatari are described, and their morphologies are compared among species and instars. Larval association for P. simoni was confirmed by DNA barcoding. Apart from a brief description of the pupa of Cryptamorpha brevicornis (W...
