Evolutionary Ecology: Insect Mothers Control Their Egg Colours

نویسنده

  • Martin Stevens
چکیده

Animal egg coloration has long provided a valuable testing ground for evolutionary ideas. A new study shows that female stink bugs can flexibly control the colour of their eggs depending on the prevailing conditions, including for protection from ultraviolet light.

Obligate symbiont involved in pest status of host insect.

The origin of specific insect genotypes that enable efficient use of agricultural plants is an important subject not only in applied fields like pest control and management but also in basic disciplines like evolutionary biology. Conventionally, it has been presupposed that such pest-related ecological traits are attributed to genes encoded in the insect genomes. Here, however, we report that p...

Prospects of herbivore egg‐killing plant defenses for sustainable crop protection

Due to a growing demand of food production worldwide, new strategies are suggested to allow for sustainable production of food with minimal effects on natural resources. A promising alternative to the application of chemical pesticides is the implementation of crops resistant to insect pests. Plants produce compounds that are harmful to a wide range of attackers, including insect pests; thus, e...

Effects of forced egg-retention in Aedes albopictus on adult survival and reproduction following application of DEET as an oviposition deterrent.

The insect repellent DEET (0.1% concentration), used as a mosquito oviposition deterrent in the laboratory, influenced the retention and maintenance of mature eggs by caged gravid female Aedes albopictus Skuse. This egg-retention mechanism could benefit survival because the gravid females were ultimately able to lay maintained eggs upon availability of water, but the length of forced egg-retent...

Influence of Electric Bulb Light Color and Type on the Attraction of Two Spotted Cricket (Gryllus bimaculatus De Geer)

Aside being a key nocturnal Agricultural pest, the two spotted cricket is an important source of protein for humans and livestock. While control is largely by synthetic pesticides, collection is majorly through hand picking and pouring of water into their burrows. In this study, we determined their phototactic response to LED and incandescent bulb light of different colours. An experiment was s...

A fecundity cost of (walking) mobility in an insect

Evolutionary theory predicts trade-offs between fecundity and mobility, but there is substantial lack of empirical evidence if and how basic mobility relates to fitness costs. In a field experiment, we investigated fecundity costs of mobility in a non-migratory, wing-monomorphic grasshopper, Stenobothrus lineatus, and at the same time tested for possible effects of reproductive state (egg-load)...
