Sentences with phrase «bloodlike hemolymph»

Similarly, we show that the mite can also vector RNAi - triggers, which were acquired from hemolymph of bees that had consumed dsRNA.

This is an Anopheles gambiae mosquito being injected with hemolymph for a malaria research study.

«Varroa mites attach to honeybees and suck their hemolymph, which is similar to blood in humans.»

When hunger strikes, the adult queen and worker ants visit the colony's nursery and cut holes into their own larvae to feed on hemolymph, the equivalent of insect blood.

Once inside a victim, the fungus feasts on the doomed creature's bloodlike hemolymph, nimbly evading prey defenses with tricks, some unknown to science.

When the fungus is finished dining on hemolymph, usually after a few days, it simply eats its way out

Most well - characterized effector molecules in other insects are secreted into the hemolymph: in our study, 91.2 % of previously identified AMPs have bioinformatic evidence indicating presence of a signal peptide.

For an ILP2 western blot analysis, we extracted hemolymph from 24 h AL3E larvae.

Based on a number of studies, we postulate that to transmit nutritional information from the fat body to the insulin - producing cells, the fat - body — derived signal would need to have the following properties: (1) it should be produced in the fat body and secreted into the hemolymph, (2) its expression and / or secretion should be amino acid - and TOR - sensitive, (3) it should act downstream of TOR signaling to stimulate ILP secretion from the insulin - producing cells, and (4) its secretion should increase IIS activity in the entire body, resulting in increased body size.

In the homozygous null mutant, we could not detect circulating ILP2 although we detected it in the hemolymph of wild - type and heterozygous animals (Fig 5A and 5B).

To confirm whether ILP accumulation in the insulin - producing cells actually results in a decrease of ILP2 concentration in the circulating hemolymph, we collected hemolymph from wild - type, and gbp1, gbp2 ex67 heterozygous and homozygous mutant larvae at 24 h AL3E, and performed western blot analyses using an anti-ILP2 antibody.

First, both GBP1 and GBP2 are produced in the larval fat body [18] and secreted into the hemolymph [18,19].

Similarly, during retrograde heart contractions hemolymph is expelled from the dorsal vessel through an excurrent opening located in the 8th abdominal segment (Figure 1A)[3].

Observation of microsphere movement in the lateral and ventral portions of the abdomen revealed that flow in the abdominal cavity is variable due to the lack of distinct hemolymph vessels.

For the measurement of hemolymph flow speeds in the ventral abdomen, mosquitoes were restrained ventral - side up by placing pins: (1) against (not through) the anterior pronotal lobe, and (2) through non-vascular areas (e.g. cell R3) of each wing without creating horizontal or vertical tension (Figure 1C).

For the simultaneous visualization of hemolymph flow through the heart and ventral abdominal contractions, as well as the quantification of hemolymph flow speeds in the lateral abdomen, mosquitoes were restrained laterally by placing pins: (1) on either side of the cervical membrane such that they crossed dorsally and restrained the mosquito between the pins and the Sylgard; (2) through non-vascular portions of each wing after they had been teased away from the abdominal tergum; (3) between the wings and the anterior portion of the abdomen; (4) over the legs, entering the Sylgard posterior to the third leg pair; and (5) immediately dorsal of the longitudinal midline of the scutum (Figure 1B).

However, in general, the periodic discharge of hemolymph from the heart and into the posterior abdomen during periods of retrograde heart contractions results in net anterograde hemolymph flow in the extracardiac abdominal hemocoel (Videos S2 and S3).

We have previously shown that during anterograde heart contractions hemolymph is expelled from the dorsal vessel through an excurrent opening located near the head (Figure 1A)[3].

The strong, exclusive correlation between abdominal and anterograde heart contractions suggests that abdominal contractions play more than an accidental role in insect hemolymph propulsion and are essential for proper hemolymph circulation.

Specifically, the abdomen contracts in a retrograde peristaltic manner exclusively during anterograde heart contraction periods, resulting in increased extracardiac hemolymph propulsion in a dorsoretrograde direction.

In the tick vector ehrlichia exist and replicate in the gut epithelium and hemolymph of the infected tick.

Insect «blood» is called hemolymph.
